Numerická simulace aerodynamické interakce křídla a trupu
Šimurda, David ; Popelka, Lukáš ; Zelený, L. ; Matějka, Milan
In order to investigate and understand extent of the wing-body interaction effects taking place during operation of a particular self-launching sailplane, commercial code Fluent 6.3 was used for numerical simulation of flow past a simplified model of TST-10a. Several methods were used to identify vortex structures originating due to interference effects in this part of the aircraft. 3D effects and distortions of pressure and velocity distributions taking place in the junction of the body and the fuselage were observed.
HIGH-SPEED AERODYNAMIC RESEARCH ON BLADE CASCADE REPRESENTING MIDDLE SECTION OF ROTOR BLADING OF LAST STAGE OF STEAM TURBINE OF LARGE OUTPUT
Luxa, Martin ; Synáč, J. ; Šafařík, Pavel ; Šimurda, David ; Šťastný, M.
The paper is concerned with results of an aerodynamic research on the midsection of the last stage rotor blade of a large output steam turbine. Data from optical and pneumatic measurements were obtained in a wide range of isentropic exit Mach numbers and angles of incidence. Velocity, loss coefficient and exit flow angle characteristics are analysed and discussed. Structure of flow fields are described using interferograms and schlieren pictures
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.
Numerický a experimentální výzkum transsonického proudění 2-D modelem mezery šroubového kompresoru
Vimmr, J. ; Bublík, O. ; Luxa, Martin ; Dvořák, Rudolf ; Šimurda, David
The main objective of the study presented here is to compare the results obtained from numerical simulations and experimental measurements of the transonic flow through the 2-D model of the male rotor-housing gap in a dry screw compressor for several clearance throat dimensions and pressure ratios.
Modelling and Measurement of a Shock Wave - Boundary Layer Interaction
Šafařík, Pavel ; Šimurda, David
Partial findings of the shock wave boundary layer interaction are summarized. Some results of measurements of the shock wave boundary layer interaction are presented.
Vysokorychlostní aerodynamický výzkum patní lopatkové mříže
Luxa, Martin ; Synáč, J. ; Šafařík, Pavel ; Šimurda, David
