Abstract:
The heat transfer and pressure drop characteristics of latticework coolant blade passages have been investigated experimentally under conditions of rotation. Stationary studies with the latticework configuration have shown potential advantages including spatially-uniform streamwise distributions of the heat transfer coefficient, greater blade strength, and enhancement levels comparable to conventional rib turbulators. In the present study, a latticework coolant passage, with orthogonal-ribs, is studied in a rotating heat transfer test-rig for a range of Reynolds numbers (Res), Rotation numbers

Abstract:
Increases in power density and thermal efficiency of a highly efficient gas turbine engine motivate an ever-mounting turbine entry temperature. The combined metallurgical and cooling advancements ensure the structural integrity of a gas turbine rotor blade that spins at high rotor speeds in a gas stream with temperatures above the melting point of the blade material. The cooling performances promoted by a variety of heat transfer enhancement methods typical of the coolant channels of the leading edge, the mid-chord region, and the trailing edge of a gas turbine rotor blade are reviewed.

Abstract:
Using the numerical simulation of the Reynolds-averaged Navier–Stokes method, the effects of two new baffle structures on the heat transfer performance of a composite cooling structure based on latticework in the leading-edge region and the mid-chord region of the turbine blade were studied. Further, the heat transfer performance of the composite cooling structure caused by the difference between the rectangular channel and the wedge channel is compared. The application potential of the new baffle is comprehensively evaluated, which provides design experience for the application of the baffle

Abstract:
Modern gas turbine blades and vanes are operated at temperatures above their material’s melting point. Active external and internal cooling are therefore necessary to reach acceptable lifetimes. One possible internal cooling method is called matrix cooling, where a matrix of intersecting cooling air channels is integrated into a blade or vane. To further increase the efficiency of gas turbines, the amount of cooling air must be reduced. Therefore it is necessary that heat transfer inside a cooling matrix is well understood. In the first part of the thesis, a methodology for estimating heat tra

This paper describes 3D numerical simulations of a turbine rotor blade with complex internal cooling structure. Conjugate heat transfer method is used to get an accurate blade temperature distribution. The cooling structure consists of a rib roughened serpentine channel near the leading edge, latticework cooling channels in the middle part and slots at the trailing edge. Both the rib roughened channel and the latticework cooling channels can enhance the heat transfer. Furthermore, the latticework cooling channels can enhance the blade strength.

Abstract Previous researches on latticework were focused on the convective heat transfer performance on pressure and suction sides of a blade model. Besides, it has an effect on leading edge by impingement. Thus, the present study provides heat transfer enhancement and pressure loss of jet impingement of a latticework on side wall in a wide channel (AR = 4). Two latticework configurations with impingement effects are employed in this study. Three kinds of sub-channel models are used in this experiment, which is according to different cooling designs.

Gas turbine engines have been widely used in modern industry especially in the aviation, marine and energy fields. The efficiency of gas turbines directly affects the economy and emissions. It’s acknowledged that the higher turbine inlet temperatures contribute to the overall gas turbine engine efficiency. Since the components are subject to the heat load, the internal cooling technology of turbine blades is of vital importance to ensure the safe and normal operation.
