Author:Klein, Peter; Roos, TH; Sheer, JDate:Aug 2014Ceramic heat regenerators are suited to providing thermal storage for concentrating solar power stations based on a recuperated gas turbine cycle. Randomly packed beds of spheres and saddles; honeycombs and checker bricks were identified as ...Read more
Author:Dunn, Dwain I; Snedden, Glen C; Roos, T; Hildebrandt, TDate:Sep 2011The design of internally-cooled gas turbine blades requires accurate predictions of distributions of blade temperature values and temperature gradients. This requires accurate predictions of heat transfer distributions from the hot gas (on ...Read more
Author:Scheepers, G; Morris, RM; Visser, JA; Roos, TH; Snedden, Glen CDate:Jan 2006This paper describes an experimental and numerical study of the heat transfer augmentation near the entrance to a gas turbine film cooling hole at different engine representative suction ratios (Vhole/V). For the experimental component the ...Read more
Author:Grobler, Carla; Sharifpur, M; Ghodsinezhad, H; Capitani, R; Meyer, JPDate:Jul 2015Natural convection is convection where the fluid motion is driven by buoyancy forces. Porous media and nanofluids have an impact on the heat transfer capabilities of thermal systems. The present experimental study is part of ongoing research ...Read more
Author:Snedden, Glen CDate:Sep 2003A comprehensive computational fluid dynamics (CFD) model of an actual disc cavity, complete with rotation and conjugate heat transfer, is presented. The model uses a commercially available code with geometrical accuracy including a labyrinth ...Read more
