The Application of the Human Model in the Thermal Comfort Assessment of Fighter Plane's Cockpit

摘要

Thermal comfort is an important content concerned by aircraft designing and using department. Computational Fluid Dynamics (CFD) is a main numerical simulation method used in this field. A human model of a pilot is built according to its geometrical and thermal features in order to simulate the air flow and heat transfer in a fighter plane's cockpit. The velocity and temperature fields are obtained by using a numerical simulation flat involving the human model above. Meanwhile, an experiment was carried out to prove the effectiveness of numerical simulation. The comparison between calculation results and experiment results shows that the calculation error of velocity and temperature is 15% and 6% respectively, which proves that the human model can be used for numerical simulation and satisfy the requirement of simulation precision. Furthermore, some thermal comfort assessment criteria such as the mean skin temperature and the core temperature of the body are obtained by putting calculation result above into the Human Thermal Regulation System (HTRS) model.
