Resumen
LAFFITA LEYVA, Alexander et al. Methodology to determine the drag force in agricultural products under computer fluid dynamic tools (CFD). Rev Cie Téc Agr [online]. 2014, vol.23, n.4, pp. 64-68. ISSN 2071-0054.
The objective of the work consists on obtaining a methodology for the determination, with the support of the Dynamics of Flowing Computational (CFD) tools, of the haulage force in agricultural products or another solid type subjected to a draft. Knowing the distribution of pressures in the surface and the coordinates of the nodes position of the finite elements´ generated mesh, a mathematical methodology is elaborated, on the base of the analytic and vectorial geometry that allows determining the haulage force that acts on the digitized pattern.
