Approach for simulation and optimisation of film cooling system in gas turbine blades

In the present paper, the system of film cooling of gas turbine blades is modelled analogous to the flow of a coolant through a rectangular slot inclined at some specific angle with the plane adiabatic surface. A Numerical Analysis Technique has been utilized for computing cooling effectiveness and the fluid properties at higher temperatures. The non-linear optimization problem is formulated and solved using the interior penalty function method with a variable metric unconstrained minimization technique.
