Patent ID: 7130782

Claim:
A gas flow simulation method comprising the steps of: setting an imaginary object model having at least one concavity, convexity, groove or projection formed thereon by means of a computer; setting a spatial part on a periphery of said imaginary object model; dividing a surface of said imaginary object model and said spatial part into a large number of latticed divisions by means of lattice points; setting said latticed divisions on said surface of said imaginary object model or in a portion of said spatial part in the vicinity of said imaginary object model in supposition of a state in which said imaginary object model is rotating; flowing a gas to said imaginary object model from one direction of said spatial part; computing a motion element of a flow of said gas in said spatial part for each latticed division, while said gas is flowing in said spatial part and passing along said surface of said imaginary object model; and simulating said flow of said gas on said periphery of said imaginary object model.
