Role of corner flow separation in unsteady dynamics of hypersonic flow over a double wedge geometry
Gaurav Kumar, Ashoke De
This study investigates the origin and sustenance of self induced oscillations of shock structures in a hypersonic flow over a double wedge configuration. Previously, various resea…
Effect of Passive flow Control of Bifurcation Phenomenon in Sudden Expansion channel
A. Mishra, M. Jithin, A. De +1
In this article we describe, a numerical simulation has been performed for a channel flow with sudden expansion. Different geometric expansion ratios are considered in the current…
Investigation of NOx in piloted stabilized methane-air diffusion flames using Finite-rate and Infinitely-fast chemistry based combustion models
Rohit Saini, Swetha Prakash, Ashoke De +1
The present work reports on the numerical investigation of NOx in three turbulent piloted diffusion flames of different levels of extinction. The study involves two-dimensional axi…
Assessment of Soot Formation Models in Lifted Ethylene/Air Turbulent Diffusion Flame
Rohit Saini, Ashoke De
In the present study, soot formation in the turbulent lifted diffusion flame, consisting of ethylene-air is numerically investigated using three different soot modeling approaches…
Large Eddy Simulation of Premixed Combustion with a Thickened Flame Approach
Ashoke De, Sumanta Acharya
A Thickened Flame (TF) modeling approach is combined with a Large Eddy Simulation (LES) methodology to model premixed combustion and the accuracy of these model predictions is eval…
Effect of Leading Edge Tubercles on Compressor Cascade Performance
M. C. Keerthi, M. S. Rajeshwaran, Abhijit Kushari +1
Tubercles are modifications to the leading edge of an airfoil in the form of blunt wave-like serrations. Several studies on the effect of tubercles on isolated airfoils have shown…
