Coupling of human thermoregulation and URANS computation for investigation of local heat transfer and flow structures in a generic car cabin
要約
Complex numerical URANS computations using direct coupling to human thermo-regulation mechanisms have been performed to analyze flow structures and heat transfer in a generic car cabin. Different flow regimes, e.g. defrost-, panel- and foot-mode, are compared regarding heat transfer, flow structures and local comfort in dependence of the inlet direction, temperature levels and position of the driver. To consider realistic boundary conditions, the heat emission of the driver is introduced using active and passive thermoregulation with application of the well-known Fiala model. Even more the heat transfer through the seat is calculated using CHT method by coupling human - seat - environment and introduction of contact boundary conditions. Computations in combination with large computational resources give a detailed overview of local flow structures and skin temperatures on the human body.
