Channiwala 2 Department of Mechanical Engineering, SVNIT, Surat, Gujarat, India Department of Mechanical Engineering, RCPIT, Shirpur, Maharashtra, India Optimization of airfoil shape using evolutionary algorithms is becoming a trend in design of blades for turbomachines and aircraft. Evolutionary algorithms work with parameterization of airfoil shape, i.e. representation of airfoil with the help of some parameters which control its shape. Thus, one of the challenges in this field is to describe the airfoil with suitable parameters and explicit or implicit mathematical functions. This paper discusses various parameterization techniques being used to parameterize the airfoil. http://pubs.sciepub.com/ajme/2/4/1/ajme-2-4-1.pdf airfoil optimization parameterization of airfoil blade optimization cascade optimization profile optimization
