Abstract:
The many parts required for aircraft and automotive development are developed by functional or sectional design groups for efficiency. Interferences and gaps can be found when the parts and subassemblies from those design groups are to be assembled. When rainwater enters the spaces between parts and there is not sufficient drainage, the rainwater within the structure can backflow to gaps or unexpected outlets, which may cause severe problems of part corrosion and electric shock. We have developed a method and a program to simulate backflow of rainwater within spaces between automotive parts; the method can find unexpected outlets and gaps. The developed program can simulate not only simple liquid flows, but also division and joining of flows with multiple channels. The developed method can also be applied to aircraft and ship design.
