Jet Diameter Effect on Impingement Jet Cooling on the Leading Edge of a Turbine Blade
by Haider, Syed Abbas, M.S., Southern Illinois University at Edwardsville, 2015, 65; 10009324
Abstract (Summary)

The effect of jet diameter on the local heat transfer from an impingement jet cooling on a concave surface simulating the leading edge of a turbine blade internal cooling surface was analyzed numerically. The study examined the flow pattern and local heat transfer distribution along the concave surface at the leading edge with jet diameter, D, of 10, 5,2.5,1.2 ,0.6 and 0.4 (mm) at a fixed Reynolds number of 8,450. The results show that as the jet diameter decreases, the internal flow pattern changes from a large single swirl vortex to multiple vortices and Nusselt number decreases as jet diameter decreases.
