Abstract
Nowadays the consideration of human temperature and comfort sensation represents an important field in the industrial application of indoor ventilation design. In some cases it is not sufficient to express the state of the human body in terms of thermal comfort by a single index for the body as a whole, as given by the model of P.O. Fanger, for example. For instance, in the interior cabin of a car, effects of solar radiation, air conditioning and seat contact have to be regarded at the same time. The resultant skin temperatures have to be computed for these locally diverging conditions in order to predict the human comfort in more detail.
As part of the major project COMFSIM, the objective of this thesis is to develop a coupling between the thermoregulation model of Fiala with an interactive simulation concept by implementing a software interface supporting a model-adaptive point of view. The Fiala model is provided by P+Z Engineering in form of their THESEUS-FE solver. The human manikin geometry is defined by a parametric model which has been developed by Yue in a master thesis at TUM in advance.
The implemented transient model is demonstrated by the interactive simulation of a simple scene (human body in a rectangular cavity). For this purpose, a virtual climate chamber has been developed using fixed heat transfer coefficients and predefined view factors. All other boundary conditions are given and can be modified during the simulation while results are updated online.
