The Simulation of Wraparound Fins’ Aerodynamic Characteristics
Authors: , ,
Abstract: To study the aerodynamic characteristics of the wraparound fins, the TTCP standard wraparound fins (WAF) model was simulated using the computational fluid dynamics (CFD) method based on the shear transport (SST) k-? turbulent model. First, the grid independence verification was considered by using three mesh systems of different densities to calculate the model’s aerodynamic coefficients. The maximum difference is within 2%. Then, the aerodynamic coefficients of the wing-wrapped vehicle model at different Mach numbers were calculated. The simulated results were compared with the experimental data, and the error could be acceptable. Finally, the WAF model’s aerodynamic characteristics as a function of Mach number and angle of attack are analyzed.
