Tip Cascade Aerodynamics of Turbine Rotor Blade 1220 mm
Rudas, B. ; Synáč, J. ; Šťastný, M. ; Luxa, Martin ; Šimurda, David ; Šafařík, Pavel
The paper is focused on aerodynamic characteristics of the tip section of a steam turbine last stage rotor blade with an active span 1220 mm. The tip cascade is aerodynamically highly loaded with supersonic outlet flow at design of Ma = 1,6. CFD simulations with a Navier-Stokes code were used to design the flow structure. The results of calculations are discussed and compared with measured flow structures.
CFD simulace hydrodynamiky airlift reaktoru s vnější cirkulací kapaliny
Šimčík, Miroslav ; Růžička, Marek ; Havlica, Jaromír ; Drahoš, Jiří ; Teixeira, J.
This contribution is aimed at CFD simulation of hydrodynamics of gas-liquid external loop rectangular airlift reactor using Euler-Euler model. Commercial code Fluent 6.3 is used to solve model equations. The goal of the work was to compare simulation results with experimental data available in literature. Simulated horizontal profiles of liquid and bubble velocity and gas holdup were compared with data from literature.
