Torsion of a Circular Shaft with a Square Cavity

Mechanics of Structures and Machines, 1987
ABSTRACT The principle of minimum total potential energy is used to calculate an approximate solution for the warping function for a hollow shaft with a circular outer and a square inner boundary. A complex polynomial series is used to generate coordinate functions that satisfy the stress-free boundary condition on the circular boundary and meet ...

Conjugate natural convection in a square porous cavity

Heat and Mass Transfer, 2001
Steady-state conjugate natural convection in a square cavity filled with a porous medium is studied numerically in this paper. The enclosure consists of two horizontal conductive walls of finite thickness and two vertical walls at different uniform temperatures.

Transition and Transition Control in a Square Cavity

2008
We study instabilities and the transition to turbulence in a square cavity. This is a generically complex yet sufficiently simple geometry that helps in the development and testing of numerical and algorithmic methods for the analysis and control of flow instabilities.

Oscillatory flow with heat transfer in a square cavity

28th Aerospace Sciences Meeting, 1989
A computational study is presented for the flow inside an oscillatory cavity. The numerical scheme employs a semi-implicit, time-splitting method to integrate the two-dimensional full Navier–Stokes equations satisfying continuity to machine accuracy. The efficient use of direct solvers for the uncoupled momentum and pressure equations is demonstrated ...

Sequential Transitions of the Thermal Convection in a Square Cavity

Journal of the Physical Society of Japan, 1997
Sequential transitions of the thermal convection in a square cavity heated from below are investigated up to the time periodic state by numerical simulation. The flow field is assumed to be two-dimensional and all the boundaries are assumed to be rigid and perfectly thermal conducting as a mathematical model. The Prandtl number is fixed as P =7.

Natural convection in a square cavity: A comparison exercise

International Journal for Numerical Methods in Fluids, 1983
AbstractA number of contributed solutions to the problem of laminar natural convection in a square cavity have been compared with what is regarded as a solution of high accuracy. The purposes of this exercise have been to confirm the accuracy of the bench mark solution and to provide a basis for the assessment of the various methods and computer codes ...

Instabilities in viscoelastic flow past a square cavity

Journal of Non-Newtonian Fluid Mechanics, 2000
Abstract Elastic flow transitions in viscoelastic flow past a square cavity adjacent to a channel are reported. The critical conditions for the onset of flow transitions and the qualitative and quantitative characterization of the secondary flows generated by the instability have been examined using streakline photography and instantaneous pressure ...

Mixed convection in a square cavity by a perturbation technique

Computational Materials Science, 2008
This paper describes a numerical solution procedure to study unsteady two-dimensional laminar mixed convection in a porous medium. It is assumed in this study that, the convecting fluid and the porous medium are everywhere in local thermodynamic equilibrium. The cavity is square and the flow is driven by a forcing flow across the top boundary. A stable
