Experimentální aerodynamický výzkum jako podpora při návrhu turbostrojů
Šafařík, Pavel ; Luxa, Martin ; Šimurda, David
The paper describes a role of experimental aerodynamic research oriented to the support of the design and computauion of turbomachines. The research techniques are briefly introduced. They are namely optical measurements of flow fields and pneumatic measurements by means of traversing. Results of the high-speed aerodynamic modelling of the flow past a blade cascade cascade representing a section in the balding of the last stage of a large output steam turbine are presented.
Experimentální výzkum transsonického proudění v 2-D modelu těsnící mezery
Luxa, Martin ; Dvořák, Rudolf ; Šimurda, David ; Vimmr, J.
The paper deals with experimental modelling of the flow through the 2-D model of the male rotor sprocket - housing gap in a screw compressor. The optical schlieren method was used as well as the pneumatic measurement methods.

Numerické řešení transsonického turbulentního proudění v turbínové mříži
Kozel, K. ; Louda, P. ; Příhoda, Jaromír
The transonic flow through a two-dimensional turbine blade cascade was numerically simulated. The mathematical model of the transonic flow is based on the implicit AUSM finite volume method and a two-equation SST turbulence model. Results were compared with experimental data
