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…
Numerical Study of Bifurcating Flow through Sudden Expansions: Effect of divergence and geometric asymmetry
Jithin M, Alok Mishra, Ashoke De +1
A numerical study of laminar flow through symmetric and slightly asymmetric sudden expansion, of expansion ratio 1:3, in channels with increasing cross section, is carried out usin…
An Experimental and Computational Study of a Swirl-Stabilized Premixed Flame
Ashoke De, Shengrong Zhu, Sumanta Acharya
An unconfined strongly swirled flow is investigated for different Reynolds numbers using particle image velocimetry (PIV) and Large Eddy Simulation (LES) with a Thickened Flame (TF…
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…
Simulation of Coupled Heat and Mass Transport With Reaction in PEM Fuel Cell Cathode using Lattice Boltzmann Method
M. Jithin, Saurabh Siddharth, Malay K. Das +1
Fluid, heat and species transport and oxygen reduction in the cathode of a PEM fuel cell are simulated using multi relaxation lattice Boltzmann method. Heat generation due to oxyge…
