  A modification has been done in the normal injection hole of 35 degree, by
injecting the cold fluid at different angles(compound angle) in lateral
direction, providing a significant change in the shape of holes which later we
found in our numerical investigation giving good quality of effectiveness in
cooling. Different L/D ratios are also studied for each compound angle. The
numerical simulation is performed based on Reynolds Averaged
Navier-Stokes(RANS) equations with k-epsilon turbulence model by using
Fluent(Commercial Software). Adiabatic Film Cooling Effectiveness has been
studied for compound angles of (0, 30, 45 and 60 degrees) and L/D ratios of (1,
2, 3 and 4) on a hole of 6mm diameter with blowing ratio 0.5. The findings are
obtained from the results, concludes that the trend of laterally averaged
adiabatic effectiveness is the function of L/D ratio and compound angle.
