摘要(Abstract):

本文针对由圆筒机壳和内锥芯体组成的环形扩压器进行了理论计算和大量的试验研究,深入探讨了旋绕对其内部流场和性能影响的规律。结果表明,在环形扩压器入口给予适当旋绕能够显著改善扩压器的流场和性能,从而为此类扩压器的设计和研究提供了一种有效的手段。
The internal flow and performance of an annular diffuser composed of a cylindrical casing and a conical hub were investigated theoretically and experimentally. It was resulted that by giving an adequate whirl flow component at the inlet can acquire the best pressure recovery and that can be used as an useful means of examination of annular diffuser.
