Abstract
Does estimated that between 10% to 25% of the loss of the grain crop occurs post-harvest. Drying grains is one of the most critical steps in grain processing for its proper conservation after harvest. Considering that grain mass is an amount of solid and empty spaces (holes) through which a fluid can pass, grain drying can be assumed to be a coupled open-porous medium problem. In this paper is proposed a mathematical and computer simulation model. It describes convection in a free flow with a porous obstacle applied to grain drying. A computational fluid dynamics scheme was implemented in FORTRAN using Finite Volume to simulate and compute the numerical solutions. The code is parallel implemented using OpenMP programming interface. There was a significant reduction in processing time. The total simulation time was eight times less for a multicore architecture (16 physical cores).
