Physico-chemical and cooking characteristics of Azad basmati
No full textThe experiment was conducted to study grain quality characteristics of Azad Basmati and to compare with other prominent Basmati rice varieties. The result of an experiment on various milling characteristics of Basmati rice varieties, among which Azad basmati exhibited high hulling (73.53%), milling (65.77%) and the highest head rice out-turn, having long-slender, translucent, creamy white kernels. Kernel dimensions of Azad Basmati were satisfactory in respect of breadth (1.60 mm) and Length/Breath (L/B) ratio (3.93) but kernel length (6.28 mm) fell marginally short than the desired minimum kernel length for Basmati rice (6.6 mm). On cooking Azad Basmati exhibited highest kernel elongation ratio (KER) and volume expansion ratio (VER) 2.20 and 4.00, respectively. Azad Basmati turned-out to be the best in respect of hulling rice recovery (HRR) (62.67%) as compared with all the check varieties (43 to 50%). Kernel breadth and L/B ratio of Azad Basmati were comparable to most check varieties, however, fell marginally short in respect of grain length than the desired minimum acceptable standard of 6.6mm. All the check varieties except Basmati-370 were comparable to Azad Basmati in respect of volume expansion ratio (VER). All check varieties in respect of VER, KEaC and KER were not found to be significantly better than Azad Basmati excepting Basmati-370 and Pusa Basmati-1 in respect of VER and KEaC, respectively. Azad Basmati variety was high (22.8%) in amylose content (AC) as compared to evolved basmati varieties Basmati-370, Pusa Basmati-1 and Basumathi but found lower than Type-3 and Improve Pusa Basmati-1 and, Azad Basmati was found intermediate except Basumathi
Recent trends and challenges of algal biofuel conversion technologies
No full textAzad, M ORCiD: 0000-0001-8258-6057The rapid growth in global energy demands has triggered the scientific community to explore new stepwise biofuel conversion approaches. Biofuels are considered as one of the most promising renewable alternatives to meet the global energy crisis and environmental concerns. Microalgae biomass has proven the potentiality for the production of biofuels, chemicals, and bio-based products leading to the transition from petroleum-based economy to a bio-based economy. Algal biofuel offers a number of advantages, for example, higher growth rate with no competition with food and minimal or no environmental impacts. Biofuel produced from microalgae has low viscosity and low density with high caloric value compared to cellulosic biofuel, which makes algal biofuel more suitable for the application. This chapter outlines the progress on the biofuels production from algal biomass. The process description of possible algal biofuel routes underlining the challenges associated with large-scale production have been detailed in this chapter
Investigation of diesel engine in cylinder flow phenomena using CFD cold flow simulation
No full textAzad, M ORCiD: 0000-0001-8258-6057This chapter investigates the computational fluid dynamic (CFD) simulation of diesel engine cold flow behavior at the speed of 2400 rpm. In this investigation, a three-dimensional (3D) combustion chamber model with an inlet and exhaust port was developed using the numerical tool. The dynamic meshing was done for different piston positions, inlet, and outlet valves operation for the entire range of the engine cycle (0°–720° crank angle (CA)). The standard k-ε turbulence model was used for CFD analysis to observe velocity, pressure, and temperature distribution. The entire process is highly complex, which requires more computational time with the powerful machine. The numerical simulation was carried out using a high-performance computing (HPC) system with 16 parallel cores and a 100 GB memory machine. The result shows the outstanding in-cylinder flow behavior, velocity, temperature, pressure, and turbulent kinetic energy for the diesel engines. The outcome of this study will be helpful to the engine designers for designing a fuel-efficient engine combustion chamber with minimum emission

Numerical Modeling of Flow and Aeration System of the AZAD Dam’s Spillway Using ANSYS FLUENT Model
No full textIntroduction:
Cavitation is one of the most important problems that may occur due to high flow velocity in dam spillways. In order to predict of dam spillway structure during operation, Azad dam spillway hydraulic model has been modeled in Tehran Water Research Institute.
Materials and Methods:In this study, using computational fluid dynamics in the form of a finite volume method used in ANSYS FLUENT software, flow modeling in these channels, and a fluid volume model (VOF) in a three-dimensional state, including two-phase flow of water and air, used for Considering current turbulence, k-ε model has been used. In order to confirm the results of the model, a comparison was made with the results of a hydraulic model implemented without the aero-damping system of Azad spillway.
Findings:Then, in order to confirm the location and number of aeration systems, two scenarios (two and three aeration systems) including step ramp (RAMP) on the floor and the wall of the duct with a suitable slope and the installation of the aeration slot in the wall have been used, which sends air near the floor And the walls will be.
Conclusion:Then, by checking flow parameters such as speed, pressure and cavitation index, overflow with two aeration systems was confirmed as the best option
Investigation on the effect of butanol isomers with gasoline on spark ignition engine characteristics
No full textAzad, M ORCiD: 0000-0001-8258-6057This chapter aims to explore the performance and emission characteristics of butanol isomers in order to suggest technical improvisations for their adoption as a commercial fuel in spark ignition engines. The limited availability of research works using butanol isomer blends motivates the current work involving an extensive investigation of the alternative fuels as a comparative study. Through extensive evaluation of the prevailing research works, it is found that by substituting pure gasoline fuel with butanol-gasoline blends, an increase in the carbon monoxide and hydrocarbon emissions due to the lower calorific value and higher latent heat of vaporization of butanol fuel can be obtained. However, oxides of nitrogen emissions are found to decrease with reference to that of pure gasoline fuel. The current study is extended to validate the results obtained from a review study by conducting an experimental investigation on an SI engine fueled with n-butanol-gasoline blend and isobutanol-gasoline blend. The concentrations of butanol isomers in the blends are varied from 10% to 30%, and the obtained performance and emission characteristics are compared to that of pure gasoline fuel. It is observed that the experimentally obtained characteristics are in accordance with the results obtained through comparative evaluation
