摘要
结合气动系统运动的实际情况 ,提出一种考虑管路特性及摩擦和传热的气动系统一维非定常可压缩流场计算方法 ,并在气动系统的流场计算中引入等压模型和压力回复模型来处理边界条件 ,通过计算结果和实验结果的对比 。
Based on the specific conditions of a pneumatic system the authors have come up with a method for calculating its one dimensional nonsteady compressible flow field with the pipe channel feature as well as the friction and heat transfer being taken into account. In addition, introduced into the calculation of the pneumatic system flow field was a constant pressure model and a pressure recovery one to treat the relevant boundary conditions. A comparison of the calculated results and the test ones has validated the precision of the proposed method.
