Prediction of separation and transition on a low-pressure turbine blade using a RANS grid
Rajesh Ranjan, S. M. Deshpande, Roddam Narasimha
Flow past a high-lift low-pressure turbine (LPT) blade in a cascade could be quite complex as phenomena like separation and transition are often involved. For a highly loadedT106A…

A Robust Approach for Stability Analysis of Complex Flows Using Navier-Stokes Solvers
Rajesh Ranjan, S. Unnikrishnan, Datta Gaitonde
Direct methods to obtain global stability modes are restricted by the daunting sizes and complexity of Jacobians encountered in general three-dimensional flows. Jacobian-free itera…

An assessment of the two-layer quasi-laminar theory of relaminarization through recent high-Re accelerated TBL experiments
Rajesh Ranjan, Roddam Narasimha
The phenomenon of relaminarization is observed in many flow situations, including that of an initially turbulent boundary layer subjected to strong favourable pressure gradients. A…
