摘　　要：本文根据轴向超音来流风扇流动特点，给出其流场数值模拟的边界条件，并依据出口流动状况对计算域提出相应要求，对两种轴向超音来流风扇转于内流动进行了数值模拟。Based on the characteristics of flow-field in axial-supersonic incoming flow fan,a modified N-S solver has been developed. Nurnerical simulations about two type of axial-supersonic incoming fiow fan rotors, i.e. ITSF and SRSF, were proceeded. Rational resultswere obtained, and shown that it could not succeed for the two rotor designs, especially forSRSF, without full consideration about three-dimensionality of such highly loaded fan rotors.
