Model of Heat and Mass Transfer with Moving Boundary during Roasting of Meat in Convection-Oven

چکیده
A 2D mathematical model of coupled heat and mass transfer describing oven roasting of meat was formulated from first principles. The current formulation of model equations incorporates the effect of shrinkage phenomena and water holding capacity. The model equations are based on conservation of mass and energy. The pressure driven transport of water in meat is expressed using Darcy’s equation. The arbitrary Lagrangian–Eulerian (ALE) method was implemented to capture the moving boundary (product-air interface) during the roasting process. The model equations were solved using the Finite Element Method (Multiphysics version 3.5). The state variables (temperature and water content) were predicted. The effect shrinkage on both predictions was evaluated.

The present study considers the numerical examination of an unsteady thermo-solutal mixed convection when the extra mass and heat diffusions, called as Soret and Dufour effects, were not neglected. The numerical simulations were performed in a lid-driven cavity, where the horizontal walls were kept in constant temperatures and concentrations. The vertical walls were well insulated. A finite vol...
