Tutorial 02 : Heat Transfer analysis of earth air tunnel heat exchanger (EATHE) using OPEN-FOAM Figure 2.1 (a) Temperature Contour of EATHE domain with BCs Figure 2.1 (b) Meshed domain of EATHE section Problem Identification In this problem investigation of EATHE using OPENFOAM is proposed for heat transfer modeling, in which air is flow in EATHE section from one inlet condition, which is assumed at surface of soil structure (See the following figure). Air properties are selected from literature available in digital medium. Outlet is at top of the room which is selected for cooling effect of EATHE system. Some assumptions are applied in this problem like soil temperature is assumed at constant value for this problem. Air properties are also assumed constant for this problem. “ buoyantBoussinesqPimpleFoam ” is selected as solver for this problem. Open Foam software is installed on Win 7, provided by FSD blueCAPE Lda: http://bluecfd.com / Note : This tutoria...
