Phase change problems with free convection: fixed grid numerical simulation

Study of Free Convection in binary systems with Phase Change

A numerical method for phase-change problems

A highly accurate and efficient finite-difference method for phase-change problems with multiple moving boundaries of irregular shape is developed by employing a coordinate transformation that immobilizes moving boundaries and preserves the conservative forms of the original governing equations. The numerical method is first presented for one-dimensional phase-change problems (involving large d...

Numerical simulation of the free convection flow in porous medium

The scope of this paper is to present, both from a theoretical and a practical viewpoint, the problem of the thermal boundary-layer approximation for free convection flow in a porous medium bounded by a vertical flat plate (wall). The influence of the wall temperature and heat flux on the problem solution is discussed. We present numerical results for the problem of steady free convection using...

Numerical simulation of Laminar Free Convection Heat Transfer around Isothermal Concave and Convex Body Shapes

In the present research, free convection heat transfer from isothermal concave and convex body shapes is studied numerically. The body shapes investigated here, are bi-sphere, cylinder, prolate and cylinder with hemispherical ends; besides, they have the same height over width (H/D = 2). A Numerical simulation is implemented to obtain heat transfer and fluid flow from all of the geometries in a...
