Nonlinear Finite Element Model for Transient Heat Transfer Under Soil with Plastic Mulch in Agriculture Applications

Authors: Carlos Armando De Castro, Orlando Porras Rey

In this paper, transient heat transfer under soil with plastic mulch is modeled using quadratic finite elements in the Galerkin approach. The model is nonlinear because of the radiative heat exchange between the soil surface, the plastic mulch and the atmosphere. Model validation was done experimentally by measuring the temperature of the soil surface in a terrain in the Savanna of Bogotá in Colombia, giving good approximation of the model to the measured data. Keywords: heat equation, finite element method, nonlinear boundary conditions, plastic mulch, atmospheric radiation
