A study on RANS computation for aerooptical effects

A RANS method for aerooptical effects has been developed. An evaluation of compressible flow RANS model has been conducted and a model had been chosen to predict main flow density distribution better. A convect equation had been used to model the refractive index fluctuation. The aerooptical effects over a aerooptical turret is evaluated and analyzed using the method developed in this paper.
