Wing Optimisation for a tractor propeller driven Micro Aerial Vehicle
Arjun Sharma, Roddam Narasimha
This paper describes an investigation of the possible benefits from wing optimisation in improving the performance of Micro Air Vehicles (MAVs). As an example we study the Avion (3…
The role of the `monopole' instability in the evolution of 2D turbulent free shear layers
Saikishan Suryanarayanan, Garry Brown, Roddam Narasimha
The role of instability in the growth of a 2D, temporally evolving, `turbulent' free shear layer is analyzed using vortex-gas simulations that condense all dynamics into the kinema…
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…
Non-Precipitating Shallow Cumulus Clouds: Theory and Direct Numerical Simulation
S. Ravichandran, Roddam Narasimha
We model cumulus clouds as transient diabatic plumes, and present a single-fluid formulation for the study of the dynamics of developing shallow cumulus clouds. The fluid, air, car…
Turbulent Jet: A DNS Study
Sachin Y. Shinde, Prasanth Prabhakaran, Roddam Narasimha
The entrainment of ambient fluid into a turbulent shear flow has been a topic of wide interest for several decades. To estimate the entrainment of ambient fluid into turbulent jet,…
Laboratory Investigations of the Dynamics of Anomalous Entrainment in Cumulus-cloud flows
Sourabh S. Diwan, Roddam Narasimha, G. S. Bhat +1
Anomalous entrainment in cumulus clouds has been a topic of investigation over many decades in the past. Its importance stems from the fact that entrainment rate is one of the majo…
