Análisis 2D y 3D de intercambiador de calor enterrado vertical

Abstract

El objetivo de este trabajo es modelar el funcionamiento de un intercambiador geotermico de calor vertical (GHE) para una configuraciOn determinada mediante tecnicas computacionales. Para ello, se introduce a una geometría mallada los datos experimentales de entrada de un ensayo TRT, obtertiendose como resultado la temperatura del flujo de salida a lo largo del tiempo. El ajuste de Ia salida del modelo con dichos datos indicara si los coeficientes característicos (conductividad, capacidad calorífica y densidad del terreno y relleno, resistencia térmica del relleno) son adecuados o no. Para la ejecución de este trabajo es fundamental el maIlado de la geometría y Ia imposición de las condiciones de contorno.

The aim purpose of this assignment is to create an operational model of a Geothermal Heat Exchanger (GHE) to work with different aspects of computational techniques. For that reason, it is introduced a meshed geometry with experimental inlet data from a TRT test, obtaining the outlet temperature of the flow along the time as a result. The outlet fitting of the model with this data show if the characteristic coefficients (conductivity, calorific capacity and land and filler density, land thermal resistance) are suitable or not. To elaborate this project, it is elemental meshing geometries and the imposition of boundary conditions.
