Aerodynamic Optimization Under a Range of Operating Conditions

Aerodynamic Optimization Under a Range of Operating Conditions

In aerodynamic design, good performance is generally required under a range of operating conditions, including off-design conditions. This can be achieved throughmultipoint optimization. The desired performance objective and operating conditions must be specified, and the resulting optimization problemmust be solved in such amanner that the desired performance is achieved. Issues involved in fo...

Thermodynamic Optimization of Tube-Fin Evaporators Operating under Frosting Conditions

In this study, the method of entropy generation minimization (i.e., design aimed at facilitating both heat, mass and fluid flows) is used to improve the evaporator geometry (aspect ratio and fin density) considering the irreversibilities produced by the heat and mass transfer, and viscous flow processes. A fully algebraic semi-empirical model was put forward to simulate the thermal-hydraulic be...

Performance of Photovoltaics Under Actual Operating Conditions

Aerodynamic optimization of a 5 Megawatt wind turbine blade

Wind power has been widely considered in recent years as an available and a clean renewable energy source. The cost of wind energy production is currently the main issue, and increasing the size of wind turbines can reduce wind energy production costs. Hence, megawatt wind turbines are being rapidly developed in recent years. In this paper, an aerodynamic analysis of the NREL 5MW turbine is...
