Title:
METHOD FOR SIMULATING GAS FLOW
Document Type and Number:
Japanese Patent JP3532528
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To visualize effects of a gas flow by a dented part of an object surface.
SOLUTION: The object having the dented part at the surface is formed by a computer, and at the same time, a part of the surface of the object is extracted including the dented part. A space contacting the extracted surface is partitioned to blocks, whereby a space part is formed. The space part is segmented to form many lattice segments. For simulation, the gas is sent from one direction to the space part, and the motion of the gas is calculated for each discrete lattice segment by a continuous equation and a Navier-Stokes' equation by every minute time. The motion of the gas is visualized by a visualization program based on the calculation results.
