Abstract
At high speeds, transonic and supersonic, the wave drag coefficient is a significant part of drag coefficients and it depends on the front surface shape and flow velocity. Drag, wave drag, drag coefficient, and wave drag coefficient for four bodies with the same width, height and length, and different shapes are estimated by CFD (ANSYS Fluent). For different front surface curvatures, at high flow velocity, pressure distribution on the front surface of the body, and flow field as a contour of Mach number are analyzed. The influence of front surface curvature on detached shock wave distance is determined.
