average human body heat in a room

alessandro.zomparelli · June 13, 2011, 10:40

Hi to all! I'm new in CFD simulation and I'm intrested in simulating natural ventilation in architectural environments. For a better evaluation of fluxes I need to consider human body heat transfer. Whereas human body heat is more or less 100W per person, how can I consider this in my simulation? I tried separating volumes of different rooms and introducing a "source energy term". The problem is the following: I can't set an absolute value for whole room in [w], but only a value relative to the volume of the room [w/m^3]. There is a way for setting it without evaluating the volume for every room?

Any suggestions? Do you know literature or articles about to house heat emission? (bathroom, kitchen, living, bedroom ecc...)

thank you very much!

hi alexandro,
have you solve your problem.i had come across similar problem.I considered human as a cylinder with wall heat flux of 100W.
