| Abstract: | A simple new method to solve the initial value problem of viscous flow around bod ies of revolution is given.And by using the method, the flow around the ellipsoid has been calculated and analysed.The effects of attack angles and body shape on the flow have been discussed.Meanwhile, particular attention has been given to the determination of separation and circumferential reversed flow (CRF).The calculation results agree with experimental data. |
