Abstract
Blade-fluid heat transfer effects in turbomachinery can have influence on its performance. With high rotational speeds, the dynamic parameters need to be considered, because they cause significant gradients of velocity, pressure and as a result – temperature. Three-dimensional numerical analysis of two radial compressor blades was conducted. Calculations were done for various rotational speeds. Air, treated as compressible ideal gas, was chosen as the working fluid. Results showed only a small change in heat absorbed by the blade due to an increase in rotational speed. Its value did not affected the efficiency and pressure ratio significantly. The main cause of this change was connected with turbulent eddies, occurring due to flow separation, as the result of second blade’s design drawbacks.
