Abstract

Aerodynamic heating has an important role on hypersonic flying bodies. The ANSYS Fluent 17.0 has been used in this study to investigate the aerodynamic heating and temperature predicted in an ogive and conical noses of a fly body. The results were compared for two noses of similar dimension, material and properties.Dynamic mesh mustbe used to simulate motion of the body nose at different attack angle and User Defined Function (UDF) is applied in the study to control the mesh deformation and to define its motion of body nose. The results presented herein are found that the magnitude of the internal heat distribution of temperature over the body nose is directly proportional with Mach numberand attack angle. Moreover, as the attack angle increases, the heat distribution of temperatureon the lower surface be much greater than it's on the upper surface. Finally, the heat distribution of temperature for a conical nose is higher than for an ogive nose about 3%. The obtained results in the present work are compared with analytical results to show the validation.
