  1. It adopts reynolds time - average n - s equation and k - ? turbulence model to calculate the inner 3 - d viscid turbulence flow of centrifugal pump. in the unstructured grid, the governing equations are discretized with finite volume method based on finite element method. then the pressure correction method is used to carry out numerical calculation

    而後採用基於雷諾時均n - s方程與標準-湍流模型來求解離心泵葉輪內三維粘性紊流，在非結構化網格中，採用基於有限元的有限體積法對方程進行離散，用壓力校正法進行數值求解。
  2. Secondly, the relation between nusselt number and the local time - averaged velocity and temperature fields of turbulent convection was theoretically induced, which expands the field - coordinated enhancement principle to turbulent convective heat transfer

    然後，在理論上導出了紊流對流換熱的整體換熱性能與局域時均速度場和時均溫度場的一般關系式，將對流換熱的場協同強化原則擴展至湍流換熱。
  3. At the same time, contour stream line, vortex, kinetic energy which are computed are important to investigate complex flow and turbulent flow

    同時得到其它的參數如渦量場、等流函數線、紊動能等，這些參數對復雜流動和湍流有重要的研究意義。
  4. The results show that rsm can accurately simulate the movement of the turbulent buoyant flow in reservoir and the anisotropic turbulence due to the thermal stratification. however, rsm is difficult in convergence, bad stability and more time consuming. rsm is suitable when the high accuracy is concerned and geometry boundary is simple

    結果顯示， rsm模型能精確模擬水庫中湍浮力流運動規律和由於溫度分層引起的紊動量的各向異性的特徵，但其收斂性、穩定性及經濟性較差，適用於計算精度要求較高且流域邊界較為簡單的流動。
