摘要: 从平板射出的垂直射流和与平板平行的低速来流(横流)相干涉,会产生复杂的流动现象。射流被横流折转,速度很快衰减,来流受到射流的阻塞和引射(图1)。射流和来流相互作用,使射流下方发展出两条对称的涡核。

Abstract: A three-dimensional computation of a jet in a crossflow has been performed on a microcomputer. The SIMPLE method is adopted with some modifications. A special computer code is developed in conformity with the limited memories of the microcomputer. Velocity and presure distributions are given and compared with the available experimental data satisfactorily.
