Three-Dimensional Unsteady Thermal Stress Problems in a Finite Circular Composite Cylinder under Periodic Heating

Thermal Field Around a Circular Cylinder with Periodic Vortex Shedding

A numerical study is carried out to investigate the laminar forced convection heat transfer from a circular cylinder. The fluid is assumed to be incompressible, the Reynolds number ranged from 0.1 to 1000, and the Prandtl number was equal to 0.7. The range of study includes heat transfer in creeping flow (Re40). The equations were discretized by a control-volume-based finite difference techniqu...

Three-Dimensional Instabilities in the Wake of a Circular Cylinder

Mark Thompson Kerry Hourigan John Sheridan Department of Mechanical Engineering, Monash University, Clayton, Australia • The twoand three-dimensional wake structure behind a circular cylinder has been computed using a high-order spectral element technique. For the two-dimensional computations the predictions are compared with accurate experimental results and agree to within experimental uncert...

Steady-Periodic Heating of a Cylinder

Unsteady Axisymmetric Stagnation Flow on a Circular Cylinder

Unsteady, axisymmetric stagnation flow about a circular cylinder is examined when the far-field flow is a periodic function of time with a fixed time average and an oscillatory part of prescribed amplitude and frequency. Solutions are computed for arbitrary values of the Reynolds number, quantifying the effects of surface curvature, and a frequency parameter based on the period of the far-field...

Simulation of Unsteady Laminar Flow around a Circular Cylinder

Abstract In this paper, unsteady laminar flow around a circular cylinder has been studied. Navier-stokes equations solved by Simple C algorithm exerted to specified structured and unstructured grids. Equations solved by staggered method and discretization of those done by upwind method. The mean drag coefficient, lift coefficient and strouhal number are compared from current work at three diffe...
