... of film coverage patterns from a baseline design, allowing film injection to overcome the crossflow and to cover more areas of the endwall with a given amount of coolant. Experimental conjugate heat transfer validation of the newly designed cooling geometry was conducted in a linear vane cascade...

... within these passages and thus greatly affect their flow loss and thermal performance. In this study, internal swirl cooling and jet impingement cooling subjected to particulate deposition were evaluated and compared using a conjugate heat transfer method, with an emphasis on the thermal effects...

... conjugate analysis. The experimental study was conducted by using a conjugate heat transfer test rig with a plenum, where cooling flow is introduced. Measurements made include velocity and temperature profiles upstream and downstream of the film-cooling holes as well as the temperature at several locations...

... one-dimensional network code for the internal passages and ANSYS CFX software for conduction and external flow. Fig. 1 Conjugate heat transfer algorithm The conjugate heat transfer involves three different physical aspects: flow and heat transfer in the external domain and internal...

... and the heat transfer are investigated numerically with ANSYS CFX , utilizing the SST turbulence model. Two sets of calculations are carried out: one under the same conditions as the experiments and another according to realistic hot gas conditions with conjugate heat transfer. The aim is to identify flow...

... is solved by a Gauss-Seidel scheme. As in Ref. 9 , this paper outlines mainly numerical results. Therefore, only a brief synthesis of the conjugate heat transfer and fluid flow solver and of the implemented multiscale technique is given here. After describing the geometric configurations...
