Flow in a radial inflow turbine rotor cascade with a blade tip gap
Dvořák, Rudolf ; Červenka, Bystrik
Using numerical simulation (software NUMECA) flow in a radial inflow turbine rotor cascade with a 10% tip gap has been solved. Effects of secondary flows and flow through the tip gap on the flow structure has been investigated at 4 boundary layer thicknesses in the oncoming stream (0, 10%, 30%, 50% of the blade length). Greater boundary layer thickness decreases the aerodynamic load as well as effect of the tip gap, and secondary flows of the 2nd kind.
