Simplified Representation of Indoor Heat Sources in CFD Simulations
Original language description
The paper deals with simplified modeling of heat sources in the indoor environment based on the replacement of heat source by simple boundary conditions. The aim of this approach is to capture the influence of a real heat plume on overall air flow pattern in the room using a model which is easy to set up and can quickly produce simulation results. The replacement boundary conditions can be determined from a detailed CFD simulation (or from a measurement) of convective flow above a comprehensive model ofthe heat source. A sitting thermal manikin in enclosed room is used as an example to demonstrate the influence of different computational model aspects on the simulation results. This includes position of the replacement boundary conditions, type of turbulence model and air temperature in the room. Study elaborated in this paper is based on the results of CFD simulations both with detailed and simplified models, which are mutually compared.
