Different boattail angles and lengths were tested. Numerical results showed close to experimental observation for the similar configuration. Drag was shown minimum value at boattail angle around 14° at low-speed conditions. Effect of boattail angle, boattail length on drag of the model, pressure distribution and flow behavior on boattail surface was analyzed and discussed in details Keyphrases: Drag reduction, RANS, Skin friction, boattail model
