Near-Wall Flow in Turbomachinery Cascades—Results of a German Collaborative Project
نویسندگان
چکیده
This article provides a summarizing account of the results obtained in current collaborative work four research institutes concerning near-wall flow turbomachinery. Specific questions regarding influences boundary layer development on blades and endwalls as well loss mechanisms due to secondary are investigated. These address skewness, periodical distortion, wake interaction heat transfer, among others. Several test rigs with modifiable configurations used for experimental investigations including an axial low speed compressor, high-speed wind tunnel, low-speed turbine. Approved stationary time resolving measurements techniques applied combination custom hot-film sensor-arrays. The experiments complemented by URANS simulations, one group focusses turbulence-resolving simulations elucidate specific impact rotation. Juxtaposing interlacing their groups provide broad picture underlying phenomena, ranging from compressors turbines, isothermal non-adiabatic, incompressible compressible flows.
