Journal ArticleDOI
Locked-on vortex shedding modes from a rotationally oscillating circular cylinder
TL;DR: In this article, numerical simulations of two-dimensional flow around a rotationally oscillating circular cylinder, placed in a uniform cross flow of a constant property Newtonian fluid, are performed at a fixed Reynolds number of 200.
Journal ArticleDOI
A numerical study of forced convection from an isothermal cylinder performing rotational oscillations in a uniform stream
TL;DR: In this paper, a heated rotationally oscillating circular cylinder placed in a uniform cross flow of constant properties fluid is investigated and the two-dimensional governing equations of flow motion and energy are solved numerically on non-uniform polar grids using a higher order compact (HOC) formulation.
Journal ArticleDOI
A numerical study of initial flow past an impulsively started rotationally oscillating circular cylinder using a transformation-free HOC scheme
TL;DR: In this article, the initial development of viscous, incompressible flow induced by an impulsively started circular cylinder which performs time dependent sinusoidal rotational oscillations about its axis is investigated numerically.
Journal ArticleDOI
A class of finite difference schemes for interface problems with an HOC approach
TL;DR: In this article, the authors proposed a new methodology for numerically solving elliptic and parabolic equations with discontinuous coefficients and singular source terms, obtained by clubbing a recently developed Higher Order Compact (HOC) methodology with special interface treatment for the points just next to the points of discontinuity.
