| Abstract: | A new turbine blade's cooling technique, which was based on the theory of thermally driven, was studied further. Two kinds of experimental models with internal cooling tunnels were designed. One of which was a new coohng technique model based on the thermally driven theory and the other was a model with rib-roughed surfaces. In centrifugal field the experiments were carried out to discuss influence factors, heat transfer characteristics and to compare the heat transfer efficiency of the two kinds of experimental models. Experimental results have shown that this new turbine blade's cooling technique has a better heat transfer efficiency than that for rib-roughed surface cooling technology. |
