<p><P>PROBLEM TO BE SOLVED: To more precisely analyze behavior of particles in fluid, to obtain simulation result approximate to actual situations. Ž<P>SOLUTION: N air bubble particles are generated inside/outside a work (S4). The moving amount ΔZ of the air bubble particles is computed based on the balance of forces acting on the air bubble particles (S5). When there is no interference with the work, the air bubble particles are moved, and when there is interference, the air bubble particles are moved along the member surface of the work (S7). Furthermore, when there is a collision between the particles, move by the collision between the particles is calculated, and the speed and direction after the collision are computed (S11). After finishing the calculation, the process proceeds to a post process (S14). The locus of the air bubble particles and the deposition state inside the work are visualized. The volume of an air pocket is computed from the deposition state of the air bubble particles. Thereby, behavior of the particles in fluid is more precisely analyzed, to obtain the simulation result approximate to actual situations. Ž<P>COPYRIGHT: (C)2008,JPO&INPIT Ž</p> |
