A Project Report on Study of Velocity Profiles over Parabolic Surfaces

Abstract

An extensive experimental study of velocity profile on parabolic surfaces has been carried out. The study has been carried out using different parabolic surfaces (four numbers) and under four different values of free stream velocities inside the wind tunnel. This analysis has been carried out to understand the changes in velocity profile by changing the characteristic of parabola. In daily life we can see there are a lot of bodies around us which have parabolic shapes. Many High speed trains have parabolic leading head. The headlight of vehicles, aircraft nose etc. is also of parabolic shapes. Keeping in mind the aerodynamic significance of parabola, an attempt has been made to understand the variation of velocity profiles with the parabolic parameter and also along the longitudinal direction under different free stream velocities. For this purpose, four arbitrary parabolic surfaces of different characteristic and made up of wood have been chosen. Velocity profile along the normal direction is strong function of free stream velocity.
