Experimental and Numerical Investigation on Flowfield of Film Cooling from Multiple Holes
This paper presents the experimental and numerical investigation on flowfield of multiple film cooling hole focuses on shallow hole angle at 20°. An in-line hole configuration consist of 20 cooling holes have been considered in the present study. Investigation have been carried out at ReD=6,200 and BR=1.0 with the experimental investigation involves 3D-LDV device to capture the experimental velocity flowfield. The numerical investigation was carried out through RANS analyses with the employment of shear stress transport turbulent model. The results highlights the benefit of shallow hole angle configuration with good agreements have been achieved between the experimental and the numerical results.
