...S. M. Ananth; Massimiliano Nardini; Melissa Kozul; Nagabhushana Rao Vadlamani; Richard D. Sandberg Recent research has demonstrated the effectiveness of riblets (streamwise aligned grooves) in reducing the profile loss of low-pressure turbine (LPT) blades under high-lift (HL) loading...

... of employing surface roughness in the transitional regime to minimize the separation bubble-related losses and flush-mounted riblets downstream to further mitigate the skin-friction drag and boundary layer losses due to an increase in the TWA. Several high-fidelity scale-resolving simulations are performed...
