Simulación numérica del comportamiento térmico de un macro túnel utilizado para la producción de hongos comestibles bajo condiciones de clima tropical

Abstract

The study of the thermic behavior of protected agriculture structures passive type stablished \non tropical weather conditions still being relevant when adequate micro climate conditions are \nguaranteed for growth and development of the plants. In Colombia that behavior and the natural \nventilation phenomenon has not been studied for warm weather conditions. The goal of this \nstudy is to determine the thermic behavior and the macro tunnel structure renovation for edible \nfungus index, which was determined through numeric models CFD 3D. The results obtained \ngave an adequate thermic behavior on the macro tunnel for the predominant meteorological \nconditions on site. The obtained renovation index oscillates between 22.5 and 45.6 renovations/ \nhour for simulated cases. The CFD model was validated registering the temperature values in \nthe structure built at full scale, the results obtained shown an adequate adjustment between \nsimulated data and registered data.
