計算受迫振蕩圓柱體的升力系數、阻力系數隨時間的演化曲線和圓柱體的尾渦分佈，以及圓柱體的受迫振蕩激發兩層流體內界面的擾動，並與均勻流體的情況進行了比較分析。The relationship between the non - dimensional drag coefficient of sma plate face and time is presented, and the pressure distribution on and around the sma plate surface as well as the karman vortex configuration in the wake at a certain time are given
給出了形狀記憶合金薄板表面的流體無量綱阻力系數隨時間的變化關系，同時給出了某一時刻薄板表面及其周邊的壓力分佈和薄板尾跡中的卡門渦街形態。A kind of grid generation method based on two - dimension poisson equtions is devlop - ed into the grid generation method based on three - dimension poisson equtions in this dessertation. use this method, this paper generals the grids of glide bullet to increase range that is at three states, that is with no control rudder and no tail wing, only with tail wing and with control rudder and tail wing. this paper has calculated the aerodynamic coefficients of glide bullet to increase range that is at three states. beside this the paper has given the results and analysised the differences of the three states, and the effects of control rudder and tail wing to the lift and drag. this can give us some information about the ability of the control ruder and tail wing for increasing the range
本文在二維泊松方程網格生成方法的基礎上推導出了一種三維泊松方程網格生成方法。並利用該方法生成了繞彈體、尾翼彈、滑翔增程彈三種不同彈形的流場網格。計算了超音速來流下彈體、尾翼彈，滑翔增程彈三種不同彈形的空氣動力學系數，分析了三種不同彈形計算結果的差別；分析了控制舵和尾翼對升力和阻力的影響。
