Abstrakt

The topic of this study is to adapt the Computational Fluid Dynamics (CFD) approach used for the thermal analysis of a parametric multi-segmented human manikin model in aircraft cabins. Considering the local thermodynamics in a non uniform environment is a very important aspect while predicting the thermal comfort of passengers in aircraft cabins. The purpose of this study is to develop and demonstrate a parametric multi-segmented human manikin model that predicts the response of the human body to varying environmental conditions, as this is relevant for the analysis of thermal comfort aspects in the aircraft cabins. The objective of this research is to obtain convective heat transfer coefficients for various environmental conditions, where the interface modelling of the seat climate and the manikin is of critical importance. In this regard a parametric thermal manikin model with 48 body segments has been developed based on the settings of a thermo-physiological model. Additionally transforming body parts according to an ergonomic model which relates topological dependencies is also allowed. For linking computational codes and engineering models, a developed middleware framework has been applied as well as a parametric geometric cabin model.
