Visualization of Thermal Flows in an Automotive Cabin with Volume Rendering Method
A predictive system of thermal flow with quick turnaround time in a passenger compartment has been developed. An efficient method based on the Cartesian mesh system was used to reduce the period of analysis. The computed temperature in an automotive cabin was visualized by volume rendering techniques using an RVS LIB software library developed by NEC. Consecutive images of the flow were converted into MPEG1 movies, which gave us an overall understanding of the flow. The visualization results indicate that the present system is capable to sufficiently predict the thermal environment in a vehicle cabin at early stage of vehicle development.
