Influence of different film cooling arrangements on endwall cooling

International Journal of Heat and Mass Transfer, 2016
Abstract The complex large scale coherent vortex systems which originate and develop through the endwall passage have strong interaction with the film cooling flows near the endwall. Two full coverage film cooling arrangements on a typical flat vane endwall were investigated experimentally. The influence of coolant mass flow rate and density ratio on

Investigations of improved cooling effectiveness for ramp film cooling with compound angle film cooling jets

Aircraft Engineering and Aerospace Technology, 2021
Purpose This paper aims to investigate the film cooling effectiveness (FCE) and mixing flow characteristics of the flat surface ramp model integrated with a compound angled film cooling jet. Design/methodology/approach Three-dimensional numerical simulation is performed on a flat surface ramp model with Reynolds Averaged Navier-Stokes approach using

Predictions of Adiabatic Film Cooling Effectiveness for Effusion Film Cooling

Volume 4: Turbo Expo 2007, Parts A and B, 2007
This paper presents computational predictions of adiabatic film cooling effectiveness for effusion cooling systems with 90° and 30° holes. Predictions are performed for a range of coolant injection mass flow rates per unit surface area, G, of 0.1kg/sm2 - 1.6 kg/sm2 for 90° holes with constant pitch-to-diameter ratio of X/D = 11 and 10 rows of holes and

Research on the flow field and film cooling effectiveness of the endwall with swirling film cooling

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 2022
In order to obtain the effect of endwall secondary flow on the swirling film cooling, a geometric model of cascade is established to research the endwall swirling film cooling and swirling flow induced by prismatic jet impingement configurations. Numerical simulation is applied to investigate three jet flow configurations on the endwall film cooling ...

Effects of Curvature on the Film Cooling Effectiveness of Double-Jet Film Cooling

Volume 5B: Heat Transfer, 2014
The effect of curvature on the film cooling characteristics of Double-Jet Film Cooling (DJFC) was numerically investigated using three-dimensional Reynolds-Averaged Navier-Stokes (RANS). The low-Reynolds number shear stress transport (SST) model was employed as the turbulence closure model.
