Sonic boom is one of critical problems should be solved in the development of future supersonic transports. Boom strength is commonly estimated based on near-field pressure signature, thus it is required to predict near-field pressure signature accurately. In this study, Shock Function is adopted for mesh refinement index since shock region can be effectively detected even at coarse mesh. Adaptive Mesh Refinement coupled with shock function is applied to an axisymmetric model for validation. It is proved that this approach is useful to improve pressure signature prediction in near field.
