diagonal-flow
解釋
對角流-
In the thesis, the design method of the diagonal flow fan impeller has detailedly researched different from the previous means borrowing and extending design methods for axial flow or centrifugal type, a complete design method has presented on the basis of quasi - three dimensional design idea. the course is mainly composed of such steps as meridional surface design, inverse problem computation in meridional surface, blade shaping on stream surface, and verifying through three dimensional computation, until the design requirement is met at last
不同於以往的軸流式或離心式延長設計方法或經驗方法，本文按照準三元設計的思路給出了一套完整的設計方法，即子午面設計?子午面反問題計算?斜流流面上葉片造型?三維計算驗證優化，直至符合設計目標。 -
The diagonal flow fan has both the advantages of axial flow type and that of centrifugal type, the former of which is large coefficient of mass flow, high efficiency, and the latter is large pressure coefficient, wide span of work condition. consequently the diagonal flow type is a perfect selection for the performance zone which both the axial flow type and the centrifugal type ca n ' t reach, ant it has great value for engineering application
斜流式風機不僅兼有軸流式風機大流量系數、高效率的優點和離心式風機高壓力系數、工作范圍寬廣的優點，因而在軸流式和離心式均不能覆蓋的性能區，斜流式風機是一種理想的選擇，有著較強的實用價值。
