Periodically fully developed convective heat transfer characteristics in a two-dimensional wavy channel are investigated numerically with a constant wall temperature.

A fully developed convective heat transfer inside a two-dimensional periodically wavy channel is investigated numerically with pulsating flows under a constant wall temperature.

By using a numerical method an investigation was conducted of the fully developed laminar flow and heat transfer characteristics of fluids in two kinds of wavy channel, namely, a sine type and a triangle type.

With the flow analysis of near surge condition,tip injection and bleeding are utilized to interact on tip leakage vortex and passage shock and the corresponding influences are investigated.

The numerical simulation of the performance of axial flow transonic compressor shows that compared to the baseline, the passage shock in the negatively curved rotor moves downstream near the tip, which improves the surge margin of the compressor while moving upstream near the midspan, increasing the energy loss there, so the compressor stage with negatively curved rotor has the lowest efficiency.

Results of calculation indicates that this program can admirably simulate rotor rows flow in axial compressors and distinguish passage shock, leakage vortex pat.
