Acoustic characteristics of supersonic planar impinging jets
Nitish Arya, Ashoke De
The present work aims to study the tonal and broadband noise associated with a supersonic planar jet impinging on a flat plate. Five different cases are considered corresponding to…
Suppression of vortex shedding using a slit through the circular cylinder at low Reynolds number
Alok Mishra, Ashoke De
The present article aims to study the suppression of vortex shedding using a passive flow control technique (slit through a circular cylinder) in the laminar regime (Re=100-500). T…
Effect of vortex and entropy sources in sound generation for compressible cavity flow
Nitish Arya, Ashoke De
The present study reports the effect of different source terms on the near and far-field acoustic characteristics of compressible flow over a rectangular cavity using hybrid comput…
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…
