A twodimensional model for boiling in an active particle bed: BOIL
Abstract
In order to model twodimensional boiling in an active particle bed, a two dimensional, steady state, isothermal model was assembled, starting from the mass, momentum, and energy conservation laws. The momentum balance includes capillary and gravity effects and two phase flow pressure losses. This physical description is translated into a mathematical model and implemented as a numerical code, BOIL, using an optimized numerical solving process. One and twodimensional test cases are run to emphasize the effects of boundary conditions; heat source distribution; relative permeability laws; and Leverett function coefficient. Results allow a good level of confidence in BOIL. Twodimensional effects of capillary forces are discussed.
