运动条件下的热工水力问题通常需要在非惯性系中进行研究,从而引出重力的坐标变换和运动附加力计算的问题。本文基于严格的数学推导,得出三维转动的坐标过渡矩阵,给出流体质量力的通用展开式,并对几种典型海洋条件下流体所受质量力进行讨论,可供运动条件下流体动力学或热工水力研究参考。
Thermal-hydraulic problems under exercise conditions usually need to be studied in non-inertial systems, leading to problems of coordinate transformation of gravity and calculation of additional kinematics. Based on rigorous mathematical derivation, the coordinate transition matrix of three-dimensional rotation is obtained, and the universal expansions of fluid mass forces are given. The mass forces of fluid under several typical ocean conditions are discussed, and the fluid dynamics under fluid conditions Or thermal hydraulic research reference.
