【摘要】 本文在时间推进法与风扇气动设计相结合方面进行了探索,初步形成时间推进通流气动设计方法及相应设计程序。该方法根本上克服了流线曲率法不能解决混合型方程组的困难,能适用于超音来流风扇的气动设计。采用该方法对高负荷亚音来流风扇、超音通流风扇和超音来流风扇进行气动设计,证实了该方法相对流线曲率法具有很大的优越性。更多还原

【Abstract】 As a new aerodynamic design method, the time marching through-flow has overcame the difficulty countered by the streamline curvature method. Meanwhile this new method has been proven having more advantages than the traditional streamline curvature methods during the design process for fans. The validity and advantage of this new method can be seen from this paper.更多还原
