Benchmark of COMSOL multiphysics via in-depth floor slab test - Transient cases

Abstract

The main purpose of this article is an advanced thermal benchmark of COMSOL Multiphysics simulation tool. The program is validated by analytical and comparative verification tests provided by the International Energy Agency in Task 34 called "In-Depth Diagnostic Cases for Ground Coupled Heart Transfer Related to Slab-on-Grade Construction". Building energy simulation test cases for evaluating simulation software are created, simulated and evaluated in software COMSOL Multiphysics. Essential goal of this article is evaluating of new simulation environment for building simulations. There are compared numerically calculated thermal flow results of transient heat conduction as well as boundary convection process in COMSOL Multiphysics with analytical and numerical model outputs presented in Task 34. © 2011 Published by Elsevier Ltd.
