Analysis of Greenhouse Solar Dryer Performance for Different Designs using CFD
No full textOver the decades, solar energy has been used to support various agricultural products in different regions of the world. From the existing literature it appears that open dehydration is most commonly used for the desired application and its effectiveness is limited to some extent. To overcome the limitations, solar dehydration is proposed and carried out by various researchers. The greenhouse dryer has proven to be the most suitable technique for storing various types of fruit, vegetables and cereal products. Much research has been conducted in recent years to improve the performance of the chosen method. Traditionally it is limited to the empirical form and is then extended to CFD analysis in order to obtain efficient results through simulations. The importance of a solar dryer and the classification of solar dryers is presented in this paper
A Comprehensive in Depth Study of Domestic Refrigerating Systems
No full textRefrigeration systems are essential in everyday life, especially when it comes to food storage and preparation, as well as safety and convenience. The primary function of a home refrigerator is to preserve the quality of perishable goods. The efficiency of the refrigerator, which is largely determined by temperature distribution and air flow in the compartments, is critical to this quality. Thus, in this paper, we are attempting to shed light on the work of investigators by experimenting on various geometries of the refrigerating system in order to improve their efficiency. In addition, we have attempted to provide an overview of the DAR cycle as well as the components of the refrigeration system, which will aid scholars in understanding the fundamental operation of cooling systems
SFCL and Applications Study for Implementation in Electrical Power System
No full textThe increase in demand and consumption of electricity has led to an increase in system errors. Superconducting Residual Current Limiters (SFCLs) provide ideal performance in the power grid. The concept of superconducting fault current limiters (SFCLs) suggests two types of superconducting materials. First of all Resistive-SFCL (which is inserted directly in series with the circuit to be protected). Second, the inductive SFCL (a transformer shorted by a superconducting tube). We also explore some uses of the proposed SFCLs to limit the fault current that appears in the electrical network. The fault current level has become a major problem in the operation of transmission and distribution systems. Applying the superconducting residual current limiter (SFCL) would not only reduce the load on the equipment in the network, but can also provide a link to improve the reliability of the power system. They also make the electricity grid more efficient and more integrated
Controlling Techniques Study for UPQC in Grid
No full textPower quality has become an important factor in electrical systems. The main causes of poor power quality are harmonic currents, low power factor, fluctuations in the supply voltage, etc. For the UPQC to function properly, the UPQC power filters must be checked. This paper has covered Unified Power Conditioner (UPQC) in depth. In this article, the mathematical modeling, basic configuration and control scheme of UPQC have been discussed in detail. The different backup storage devices used in UPQC are explained with device-specific control algorithms
A Review on AI Chip Design
No full textIn recent years, artificial intelligence (AI) technologies have been widely used in many business areas. With the attention and investment of scientific researchers and research companies around the world, artificial intelligence technologies have proven their irreplaceable value in traditional speech recognition, image recognition, search/recommendation engines, and other areas. At the same time, however, the computational effort for artificial intelligence technologies is increasing dramatically, posing a huge challenge to the computing power of hardware devices. First, in this paper, we describe the direction of AI chip technology development, including the technical shortcomings of existing AI chips. So, we present the directions of AI chip development in recent years
A Review on Effect of Geometrical Variation in IC Engine Cylinder
No full textWhen fuel is burned in an engine, heat is generated. Additional heat is also created by the friction between the moving parts. The engine cylinder is one of the most important automotive components which is exposed to temperature fluctuations and high thermal loads. To cool the cylinder, fins are provided on the surface of the cylinder to increase the rate of heat transfer. When performing a thermal analysis of the engine cylinder fins, it is helpful to know the heat dissipation within the cylinder. We know that by increasing the area, we can increase the rate of heat dissipation, so designing such a large and complex motor is very difficult. The main objective is to analyze the thermal properties by varying the geometry, material and thickness of the cylinder fins using a CAD software
Comparison of Warming efficiency of Greenhouse Solar Dryer with Four Distinct Design Implementations
No full textDrying is a technique for transferring warmth from a source to a product while also removing moisture from the product in a limited space. When using sun drying, the heat required for drying is primarily provided by solar energy. In this paper we have discussed about the fundamentals of different types of green house solar dryer, and to develop new design of solar dryer that would maximize warming efficiency. The main goal of this research is to run a computational fluid dynamics analysis on a previous model to analyze the influence of the highest warming within the greenhouse solar drye

Comparison & Simulative Analysis of Low Voltage Distribution System (LVDS) with High Voltage Distribution System (HVDS) Towards Performance Enhancement
No full textAn electric power distribution system is the last stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers. Distribution substations connect to the transmission system and step down the transmission voltage to medium voltage. The work is focused on bringing about the comparative analysis on the outcomes at the load points in the low voltage distribution system and the high voltage distribution system. The results concluded enhancement in the quality issues associated with the low voltage distribution system while designing of the High voltage distribution system. The losses in the voltage and current profile were reduced to bring about enhancement in the power availability in the loading points by 3 %. To further analyze the performance of HV distribution system with renewable energy resources the hybrid system of solar and wind generation systems were developed and then were integrated with the LV system first and then with the HV system. The study again concluded improvement in the power by 2.7% reducing the losses in the voltage and current profiles. The HV system loading was also identified to reduce the effects on the 11KV high voltage distribution line. Thus it can be inferred from the study that Implementation of high voltage distribution system (HVDS) for consumers will result in reduction in losses, increase in energy saving and improve voltage profile. The adoption of HVDS makes the system more reliable and thus, reduces the number of outages. The chances of unauthorized connections and theft of energy are reduced.The restructuring of existing low voltage distribution system (LVDS) as HVDS presents one of the best technically feasible and financially viable method for providing reliable and quality supply to consumers
