Flow Characteristics of Elastically Mounted Slit Cylinder at Sub-critical Reynolds Number
Mayank Verma, Alok Mishra, Ashoke De
The present work numerically investigates vortex-induced vibrations (VIV) of a two-dimensional circular cylinder with an axisymmetric slit at Reynolds number 500. The study examine…
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…
Investigation of passive flow control over an airfoil using leading edge tubercles
Alok Mishra, Ashoke De
The present paper numerically investigates flow control over NACA0021 (National Advisory Committee for Aeronautics) airfoil by applying a leading-edge tubercle as a passive flow co…
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…
Prediction of Separation Induced Transition on Thick Airfoil Using Nonlinear URANS Based Turbulence Model
Alok Mishra, Gaurav Kumar, Ashoke De
Most of the turbulence models in practice are based on the assumption of a linear relation between Reynolds stresses and mean flow strain rates which generally provides a good appr…
Passive control of the onset of vortex shedding in flow past a circular cylinder using Slit
Alok Mishra, Mohd. Hanzla, Ashoke De
The present study investigates the passive flow control phenomena over a two-dimensional circular cylinder using numerical simulations in the laminar regime. The aim is to explore…
