FLUID SPRAY SIMULATION METHOD, COMPUTER PROGRAM, OBJECT TO BE SPRAYED, BATH, BATH MANUFACTURING SYSTEM, AND SPRAY NOZZLE

摘要

There is provided a fluid spray simulation method for verifying the sprayed state of an object to be sprayed by a spray nozzle so as to reflect a physical orbit of the fluid sprayed from the spray nozzle. [MEANS FOR SOLVING PROBLEMS] A bath model is created by TIN data and each of the apexes of the bath model are moved downward according to the mathematical expressions of the distance from the spray nozzle and the gravitation orbit. Ray tracing calculation is performed to specify the portion shaded by the light from the light source arranged at the arrangement position of the spray nozzle. After this, the apexes of the bath which have been moved downward are returned to their previous positions and visualized, thereby enabling fluid spray simulation reflecting the physical orbit considering the affect of gravitation of the cleaning fluid sprayed from the spray nozzle.
