هدف این پروژه بررسی پایداری خودرو در اثر افزایش نیروهای آئرودینامیکی وارد بر خودرو در سرعت های بالا بوده است. به این منظور پس از بررسی پیشینه موضوع و کارهای انجام شده بر روی این موضوع در فصل اول ، در فصل دوم به بررسی روش های بدست آوردن اثرات آئرودینامیکی بر روی خودروی مدل طراحی شده، پرداخته شده است. همانطور که می دانیم تونل باد مهمترین ابزار برای بدست آوردن اثرات آئرودینامیکی است. برای این منظو...
In this work, optimisation of a brushless direct current (BLDC) generator design was undertaken by carrying out an electromagnetic and computational fluid dynamic study. The studies were carried out for different loadingoverloading conditions and angular speeds, keeping in consideration the required electrical and thermal parameters, firstly for the initial design and then for optimised designs...
Synthetic jets have been an area of interest in the recent years with constantly increasing industrial demand. Application areas are widespread and a strong focus is put on boundary layer control as well as on mixing enhancement. A synthetic jet has been studied using physical experiments involving high-speed camera footage and smoke visualisation. Additionally, threedimensional transient numer...
Thermal performance of a solar water heater mainly depends on the thermal stratification. Thermal stratification in solar water tanks is essential for a better performance of energy storage systems where these tanks are integrated. In this research work, the performance of a solar water heater with a mantle heat exchanger is investigated experimentally. The heat exchanger is assessed for a rang...
Background: An economical and integrated high-throughput primary screening strategy was developed for high-aerobic microbe Monascus purpureus cultivation. A novel and effective mixture culture method was proposed and used to realize the whole mutant library being high-throughput screened after mutagenesis. Results: The good correlation of fermentation results between differing-scale cultivation...
Numerical simulations of magnetohydrodynamic (MHD) hypersonic flow over a cylinder are presented for axial- and transverse-oriented dipoles with different strengths. ANSYS CFX is used to carry out calculations for steady, laminar flows at a Mach number of 6.1, with a model for electrical conductivity as a function of temperature and pressure. The low magnetic Reynolds number (<<1) calculated ba...
Pressure distributions over a 20° conical forebody are computed by the commercial CFD software ANSYS CFX. Free stream velocity is 30 m/s, Reynolds number based on the forebody base diameter is 0.3×10 6 , and the angle of attack ranges from 10° to 35°. The C-O structural grids are used to compute the entire flow field. The governing equations are steady Reynolds-Averaged Navier-Stokes Equations ...
The high-speed dental air-turbine handpieces are widely used in the dentistry as a tool for cutting and drilling a tooth. The advanced existing high-speed dental air-turbine handpieces were investigated to design the high performance dental air-turbine handpiece. The coupler and air-turbine of the dental air-turbine handpiece was designed using computational analysis. The computational domain o...
Our numerical modelling of the Czochralski growth of single crystalline β-Ga2O3 crystals (monoclinic symmetry) starts at the 2D heat transport analysis within the crystal growth furnace, proceeds with the 3D heat transport and fluid flow analysis in the crystal-melt-crucible arrangement and targets the 3D thermal stress analysis within the β-Ga2O3 crystal. In order to perform the stress analysi...
Thermal sprayed surface coatings are extensively used for a wide range of industrial applications. In the plasma spray process used in thermal spraying, the temperature of substrate and conduction of heat along the thickness of ceramic oxide coatings (TCOC) play an important role in the bond strength and microstructure of the coatings, which decides its performance and quality. In this study, u...
