Turbine Blade Cascade Heat Transfer Analysis Using CFD –A Review

Heat transfer analysis on a turbine blade cascade using CFD is reviewed in this paper based upon the literature available. The flow conditions across turbine blades are complex because of three dimensional configuration of the blade. Axial flow turbine blade design is hectic because understanding of control flows, prediction and analysis is a tedious task. The flow behaviour in a turbine blade cascade can be understood to some extent by analyzing pressure, velocity, temperature and streamline plots. The fluid flow simulation coupled with heat transfer analysis is a common practice in CFD, to study how behaviour influences heat transfer. By optimizing design variables more efficient systems can be designed. A 3-D Navier-Stokes flow solver was applied to characterize flow which supports the flow phenomenon.
