The model of fpsa ( inter - phase slip algorithm ) provided in phofvmcs, the software used in computational fluid dynamics, which solves the navier - stokes equations of each phase with the interphase interactions between two phase of water and air, including the interphase drag forces, interphase lift forces, interphase pressure and virtual mass forces, is employed with the difference scheme of upwind and the orthonormal grid
計算採用由phoenics （計算流體力學軟體）的ipsa （相間滑移演算法）模型，應用upwind （迎風）格式和直角坐標網格。 ipsa模型對每一相求解n - s方程，並考慮水-氣體兩相間的相間互互作用，包括相間阻力、相間升力、相間壓力和虛質量力。 -
First, according to the orthonormal quality and the rational choice of working point of the sonar array three shafts frame, the structure of the models is predigested preliminarily ; secondly, according to the quality indexes and the coupling quality between frames, relatively small quantum is neglected. so the complex non - linear coupling models of the sonar array are predigested farther ; lastly, considering the characteristic of the model coefficient matrix, the methods of the low rank polynomial approach and the error simulation are introduced. so the models are predigested again
首先從聲納基陣框架結構的正交性和工作點的合理選擇出發，使模型的結構得以簡化；其次根據系統性能指標及框架間耦合性強弱，忽略相對小量，對聲納基陣復雜的非線性耦合模型進一步簡化；最後考慮模型系數矩陣的特點，運用低階多項式逼近和誤差模擬的方法，實現了對模型的再次降階簡化處理。
