Numerical analysis of aerodynamic heating effects on temperature distribution inside the ultrasonic bird cabin

In this paper, the effect of aerodynamic heating on temperature distribution inside supersonic bird cabin in different insulation conditions, the existence of gravity force and different flight height has been investigate using a computational fluid dynamics method with the finite volume approach. The coupling boundary condition in the shell wall use to simultaneously to solve the equations in solid and fluid. The air assumed as an ideal gas and the Boussinesq approximation used to changes density with temperature. In - cabin temperature distribution changes in terms of the free Convection heat transfer is simulated transiently up to a flying time of 70 seconds. The results are presented as temperature contour in the middle section of the model, temperature - time and temperature - location diagrams for different times. In this research, experimental and numerical method s are validated the temperature distribution inside and outside the model, which shows good accuracy.
