摘　　要：阐述了在侧向喷流的直接模拟和间接模拟中开展喷流形状模拟的必要性 ,认为喷流形状相似是正确模拟干扰力的保证。分析了在直接模拟中同时模拟喷流形状 (也即干扰力 )和喷流力的相容情况 ,并给出了相应的相容条件。只要满足相容条件 。The necessity of geometric shape simulation in the direct, as well as the indirect, lateral jet simulations in wind tunnel testing is presented. It is considered that the analogy of the jet shape is a guarantee of validly simulating interference forces due to the interaction between the jet and the crossflow. The compatibility associated with simultaneous simulations of the jet shape and thrusting in the direct simulations of lateral jets is analysed and discussed, and the relevant compatibility conditions are proposed. It is indicated that the simultaneous simulations in lateral jet wind tunnel testing can be realized, in principle, as long as the corresponding compatibility conditions are satisfied.
