Facility Thermal Balance and Transport
Get PDFThis Final Design Review (FDR) report outlines the senior design project completed by a team of five mechanical engineering students at California Polytechnic State University, San Luis Obispo for Senior Industrial Engineer, Mr. Tom Bass, of Entegris, Inc. The team developed an innovative system to address the issue of ice accumulation on cryogenic vaporizers at the Entegris facility. Ice buildup, caused by the extremely low temperatures of the cryogenic fluid, reduces the efficiency of vaporizers and places additional stress on the system. To combat this, the team designed and constructed a prototype that utilizes a thermal transport loop to transfer waste heat from other processes within the plant to melt the ice. The system helps to minimize additional energy consumption of the plant and avoids disrupting normal plant operations.
Testing demonstrated the system\u27s capability to capture and transfer significant amounts of heat, although it did not meet the target heat transfer rate of 150,000 BTU/hr. The prototype managed to capture up to 49,390 BTU/hr from the exhaust and transfer 31,918 BTU/hr to the enclosure. Despite falling short of the target, the system showed a high effective energy transfer rate of 288% and provided substantial cooling potential, indicating a return on investment of 188%, with the potential for the system to pay for itself in 2.4 years. Additionally, the system effectively handled increased load while maintaining manageable ice levels.
This project is of high significance because it offers a sustainable and efficient solution to improve the performance of cryogenic vaporizers and reduce operational costs at the Entegris facility. The findings and recommendations for future improvements provide a strong foundation for scaling the system to the larger vaporizers on site, enhancing overall plant efficiency and sustainability. The results of this project are widely applicable to various industries that use cryogenic ambient air vaporizers because ice buildup is a common problem that occurs with them. The results of this project are especially applicable to those that aim to improve plant efficiency and sustainability by concentrating their sources of heating and cooling to thermally balance their operations
3D Printed Plastic Aero Fluid Coupling
Get PDFThe Final Design Review (FDR) document outlines the senior design project carried out by a team four mechanical engineering students at California Polytechnic State University, San Luis Obispo. The project sponsor is the Parker Hannifin Corporation, specifically the Parker Aerospace Fluid Systems Division with oversight from Sr. Project Engineer Michael Yankauskas. The project involves designing and manufacturing the male ferrule component of an aero-fluid coupling assembly using additively manufactured high temperature engineered plastics (AM HTEP). The objective is to create a 3D printed plastic ferrule that interfaces with a preexisting SAE international standardized coupling assembly while retaining the strength, fatigue life, wear resistance, corrosion resistance, and electrostatic discharge (ESD) capabilities of the current aluminum part. The decisions behind the final design, the manufacturing process, and the testing requirements are included in this document. Furthermore, the entire project is reflected upon with next steps and recommendations listed
Moment Monument
Get PDFWe designed our project, dubbed the Moment Monument, in part to live out our dream of applying engineering and design skills towards creating a lasting impression on Cal Poly’s campus, as well as to develop a visual aid for future engineering students in steel design classes. The Moment Monument is in the Experimental Structures Laboratory, which is a space in the university’s ‘Poly Canyon’ that is reserved for students to build and test different applications of architecture, structural engineering, and construction. In recent years, it has been diffi cult to receive approval to build in the canyon due to high restrictions in place to receive a permit. However, we worked diligently for over a year and are proud that we were able to contribute to the legacy of the Poly Canyon Experimental Structures Laboratory.
The Moment Monument consists of a circular concrete slab split down the middle and shifted to create a pinwheel shape, with each of the slab’s tails ramping up to the top. This shape is representative of the right-hand rule used when summing moments in a statics class. The slab is supported by circular stem walls into foundations that are embedded below grade. The slab itself rises 12” above grade to become a raised podium for observers to walk around on and provides comfortable seating along the edge.
Rising 9’-6” from the top of the slab are six steel moment frames, three along each ramp. Each frame showcases different prequalifi ed seismic moment connections per AISC 358-16. We were exposed to the Reduced Beam Section (RBS) connection during our steel design class, and our curiosity for other types of prequalifi ed connections led us down a path of creating a visual aid for students to come to our structure and see a direct application of these connections from the AISC Seismic Design Manual. The beam to column connections are clearly visible for observation, as are the column to foundation connections. The entire Moment Monument was designed with students in mind, with the intent of maximizing the amount of applicable knowledge that can be portrayed through moment frame construction
Design, Modeling, and Testing of a Novel Inductor for Electric Vehicles: Iron Nitride Soft Magnetic Composites
No full textThe purpose of this study is to develop a processing method to reduce the porosity of toroidal inductors, whose cores are composed of soft magnetic composites (SMCs) with 65 vol.%, 75 vol.%, and 85 vol.% iron nitride (γ′-Fe4N) and to validate the results with a COMSOLTM model. Using hot-pressing as the main process of manufacture, fourteen samples were fabricated and eight were wound with Litz wire. Four samples of 75 vol.% and four samples of 85 vol.% were fabricated by mixing the Fe4N powder and epoxy at 150oC and initially pressing at 5 tons and 175oC. In a second step, the samples were pressed overnight at 5 tons and 193oC. The optimized processing method increased the density of each toroidal inductor sample by about 7%, increased mixing time, and produced markedly improved surface uniformity. Finally, the COMSOLTM model of the inductors requires further adjustments to better reflect the measured inductance due to wire gauge and construction. By the completion of this project we fabricated a sample which achieved an inductance of 368.8 μH and a density of 5.15 g/cm3
Barriers To And Solutions For Fuel Treatments In The Central California Coast Ranges
Get PDFIn recent years, the Western United States has experienced an increase in fire activity due to multiple factors, including anthropogenic climate change, historical forest management focused on suppression, and the expanding wildland urban interface (WUI). In response, California is working to accelerate the pace and scale of forest management and fire hazard reduction efforts. Although fuel treatment projects are being implemented, they often encounter various barriers. While existing literature highlights these barriers, it tends to overlook the solutions being applied in practice to overcome them. Using an ethnographic approach that includes key informant interviews and participant observation in four sites within California’s Coast Ranges, we identify both the barriers and the solutions being used ‘on the ground.’ Our findings reveal that many of the previously identified barriers elsewhere also exist in the Central California Coast Ranges. Trust emerges as a critical factor for the successful implementation of fuel treatments, yet it is not just about recognizing its importance. Our research builds on existing literature by documenting specific strategies used to overcome these barriers, showing not only that relationships and trust are valuable, but also how they can be actively developed. By addressing the interconnected variables underlying fuel treatment barriers through the intentional development of personal and professional relationships, practitioners can more effectively implement fuel treatment projects in California

Construction Management Study Abroad Program Database
Get PDFIn the Construction Management department, there are programs available for students to study abroad. The problem is that there isn’t much acknowledgement of these programs. That is because the students don’t know where to look. To help students learn more about the opportunities that await them, a database compiling all the programs was put together. Along with it, fliers will be put up to help advertise and encourage students to study abroad. It will give them the specifics of each program including cost, location, dates, advisor and more. The purpose is to provide easy access to the abroad programs so students know what is available to them and it allows validation for funding requests to the CM department which allows a more sustainable funding source for CM international travel. The Cal Poly International Center had information on each abroad program available for all students, but I focused on Construction Management related programs which there were very few of. To combat that, research was done on supplemental courses that CM students could take. In the end, a complete database was created and wasn’t limited to Construction Management major courses allowing more chances for students to study abroad and explore the world
