WebApr 1, 1999 · Cooling channels, roughened with repeated ribs, are commonly employed as a means of cooling turbine blades. The increased level of mixing induced by these ribs enhances the convective heat transfer in the blade cooling cavities. Many previous investigations have focused on the heat transfer coefficient on the surfaces between … WebJun 1, 2024 · Among the blade internal cooling methods, micro perturbation elements show the potential of high heat transfer with low pressure drop but the mechanisms remain unclear. This paper investigated the influence of micro-ribs on turbulent momentum and heat transport in the near-wall region of a micro-ribbed channel flow by Large Eddy Simulation.
