Aero-thermal optimization on multi-rows of film cooling over a flat plate has been performed to optimize the inclination angles. Hence three cylindrical holes with injection angles ?, and ? have considered. The hole 3 mm diameter an inclined angle between 25-35?. Numerical simulations were at fixed density ratio 1.25 blowing 0.5. control-volume method SIMPLEC algorithm used solve steady-state R...

Thermal stability and Surface hardness of the super-finished surface is a very important aspect to preserve texture workpiece in MAF process. In this present study, multi-objective optimization EN-31 finished through “Increase Temperature” Hardness” are considered for diminish their impact on EN-31. work Desirability function analysis (DFA) has been used optimize desired responses Experiments w...
