This paper illustrates the theory behind computational fluid dynamics (CFD) of flow though a gas turbine engine low pressure compressor. The goal of study is to develop a tool to perform shape optimization of low speed airfoils. Mathematical model and computational tool are developed using programming software. Analytical solution is developed to create airfoil geometry. The NACA 4 digits library is used with design parameters that control camber and the thickness of the airfoil. Solver is capable of providing derivatives of the objective function and limiting constraints with the solution for each set of parameters.
