The wide range of applications for radial inflow turbines is the reason for an increasing interest in this type of machines in the recent years. An appropriate method to achieve good efficiencies under different operating conditions is the use of variable nozzle vanes. Because of the limited knowledge of the flow phenomena involved, simple models are used for aero-thermodynamical machine design. A research program was initiated to experimentally study the flow field in a transonic radial nozzle cascade. An air test rig with variable nozzle vanes, derived from an industrial radial inflow turbine, was used for the tests. In this rig no rotor was installed in order to study the flow in the nozzles without any influence of this element. Static pressure distributions have been measured on the vane suction and pressure surfaces and on the shroud endwall within the blading and downstream of the nozzles. Results are presented for different pressure ratios and nozzle setting angles. The experimental results are compared with numerical calculations for inviscid flow based on the two-dimensional Euler equations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
