Abstract
In this paper a coupled simulation of radiation and convection is developed to investigate the convective and radiant heat transfer characteristics between a standing human body and the surrounding environment. The convective simulation, i.e. airflow simulation, is carried out using a low-Reynolds-number type κ-ε turbulence model. The radiant heat transfer is conducted by means of Gebhart's absorption factor method, and the view factors are obtained by the Monte Carlo method. The generalized curvilinear coordinate system (Boundary Fitted Coordinates) is used to represent the complicated shape of the human body. Fanger's model is adopted to investigate the internal heat transfer inside the body surface. The obtained results agree well with the experiments.
