4.Using mass balance equation, energy balance equation, heat and mass transfer equation, a mathematical model of heat and mass transfer during the granular materials drying has been presented. The finite element method and Matlab is used. Both the variation of material' temperature and moisture content can be predicted.
By solving the proposed model, the velocity distribution of liquid phase and concentration profiles of vapor and liquid phases can be calculated simultaneously. Complete mixing and partial mixing of vapor phase is investigated in simulating the details of mass transfer process. The result reveals that the tray efficiency calculated in the assumption of complete mixing of vapor phase is greater than the real value.
In this paper, a new method of boundary reduction is proposed, which reduces the steady-state heat transfer equation with radiation.
The seventh section consists of remarks with respect to approximations of the transfer equation.
Solution of the heat-transfer equation for equilibrium turbulent boundary layers when the temperature distribution of the stream
We give an approximate solution of the heat-transfer equation for equilibrium turbulent boundary layers for which the velocity distribution and the coefficient of turbulent viscosity can be described by functions of two parameters.
The behavior of a photon gas near a surface can be predicted on the basis of the complete radiative transfer equation.
