... and the profile of diffuser were adopted to reduce the exit Mach number, thus improving the total-static efficiency. Different from general gas turbines, microgas turbines are operated in low Reynolds numbers ( 10 4 – 10 5 ) , which has significant effect on flow separation, heat transfer, and laminar...

... conditions provided by the upstream OGV blade. These results confirmed that the secondary flow field generated at the OGV exit is significant in controlling endwall boundary layer growth and delaying flow separation in the diffuser. This implies that a flow control approach to OGV/prediffuser design could...
