[ 1 ] - محاسبه فشاربهینه بازگرمایش و خنککنمیانی در نیروگاه گازی
در این مقاله فشاربهینه بازگرمایش و فشاربهینه در خنککنمیانی در نیروگاه گاز (چرخه برایتون واقعی) شامل دو توربین، دو کمپرسور، محفظه احتراق، خنککنمیانی، بازگرمایش و بازیاب محاسبه شده است. منظور از فشاربهینه، فشاری است که در آن بازده چرخه برایتون حداکثر شود. با شبیه سازی حالتهای مختلف چرخه برایتون واقعی با نرمافزارEES و بهدست آوردن نمودار تغییرات بازده چرخه نسبت به فشار خنککنمیانی، در هر ...
[ 2 ] - A Characteristic-based Solution of Forced and Free Convection in Closed Domains with Emphasis on Various Fluids
In this paper, forced and free convection in the cavity is simulated numerically with complex boundary conditions. Temperature changes sinusoidally at the upper and right walls and the temperature of the other walls is kept at zero. The effects of Prandtl and Grashof numbers variations on flow patterns are surveyed. A wide range of materials, e.g. molten metals, gases, water, and coolant liquid...
[ 3 ] - A Characteristic-based Numerical Simulation of Water-titanium Dioxide Nano-fluid in Closed Domains
A new characteristic-based method is developed and used for solving the mixed and forced convection problems. The nano-fluid flow with heat transfer is simulated with a novel characteristic-based scheme in closed domains with different aspect ratios. For this purpose, a FORTRAN code has been written and developed. Water as a pure fluid and water-titanium dioxide as a nano-fluid were considered....
[ 4 ] - Performance study of a renewable fuel-fed micro humid air turbine
Biogas is a proven and valuable energy source today for combined production of heat and electricity (CHP). In this paper, a novel CHP system installation based on a 500 kW micro humid air turbine (mHAT) in a wastewater treatment plant (WWTP) is presented and discussed. Furthermore, some considerations regarding an appropriate biogas treatment system and heat recovery module is discussed. The re...
