Thermal Fluid Analysis By a Mesh Free Simulation - Part 2 Analysis of the Indoor Climate in a Vehicle Cabin Based on the 3D-CAD Model 2011-28-0136

The thermal fluid field in a vehicle cabin model is analyzed by the mesh free method as well as mentioned in the Part 1. This paper focuses on the steady state indoor climate in the vehicle cabin including the effect of the buoyancy, the heat generation of the driver and heat conduction through the vehicle body surface under the maximum air-cooling condition soaked in a climate chamber in the summer condition for the demonstration of the mesh free method without not only the deformation of the 3D-CAD model but mesh generation. The solar radiation distribution and heat generation through the exhaust pipe from the engine room are simply included in the analysis. Simulated results are compared with experiments in the conditions of both moving and idling states. As a result, no significant difference in air temperature between simulation and experiments can be obtained in both conditions. It is found the conducted method is recognized as a powerful tool which can analyze the indoor climate in the vehicle cabin based on the 3D-CAD model directly.
