<P>PROBLEM TO BE SOLVED: To provide a fluid analysis method and a fluid analysis device, wherein a plurality of fluids are compared with one another in the fluid properties over the whole range thereof at a low calculation cost. Ž<P>SOLUTION: The fluid analysis method comprises: obtaining a fluid state of one fluid and a flow track line by measuring a positional information point of a virtual particle in the one fluid at each time and connecting the measured positional information points to one another time-sequentially until an optional time; mapping data on the flow track line onto an evaluation model expressed by minute elements; counting the minute elements of the evaluation model each of which comprises even a part of the flow track line; obtaining an index by dividing the counted number by the total number of the minute elements of the evaluation model; and making an evaluation by comparing the obtained indexes of the plurality of fluids with one another in the fluid properties. The fluid analysis device is also provided. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
