For instance, one type of tunnel is required for fundamental tests of the cascades; a second is required for high altitude engine performance tests. Experimental models for these tests consist of real engine components or of close replicas. Certain effects may not be adequately addressed in wind tunnel tests, for example, the effects of high speed revolution, flow properties in unmeasurable regions, realistic boundary conditions. The twofold object of computational fluid dynamics (CFD) for internal flows is to predict the performance of models before expensive wind tunnel tests are done and to provide information of the internal flow that is inaccessible to experiment measurement. CFD is already useful for improving designs or making new ones. As computers and CFD technology advance, CFD can expand from the role of prediction and design to that of a numerical wind tunnel. This paper shows how features of numerical wind tunnels parallel those of experimental wind tunnels The paper also assesses future trends for the use of numerical wind tunnels., 資料番号: NALSP0016053, レポート番号: NAL SP-16}, title = {IHI航空エンジンにおける風洞実験とCFD}, year = {1991} }
