<p><P>PROBLEM TO BE SOLVED: To provide a fluid analysis method and a fluid analysis device, which compare flow characteristics of a plurality of fluid over the entire fluid region at a low calculation cost. <P>SOLUTION: The fluid analysis method includes steps of: determining the flow state of the fluid and a streak line connecting positional information of virtual particles in the fluid at each time till an arbitrary time; calculating the volume after calculating the summation form by Boolean operations to a three-dimensional structure generated by expanding a plane along the streak line using the streak line as an axis; and comparing and evaluating the flow characteristics of the plurality of fluid using as an index a value obtained by dividing the volume by the volume of a stirring device. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
