Heat transfer enhancement in stagnation region of aero-engine inlet vanes due to ejection slot and anisotropic heat conduction 2019-01-2040
In this work, an anisotropic heat conductivity for composite solids which can take account of the curvature of the material has been developed and implemented into ANSYS Fluent. This model was then used to study the effects of anisotropic heat conductivity on the stagnation point temperature in aero-engine inlet struts. The results of this study were that anisotropic heat conductivity plays a big role in engine struts with low ejection angles for the hot gas. With a rising ejection angle the effect gets smaller as the thermal conductivity of the composite material is very low and the path for the heat is too long.
