<p>PROBLEM TO BE SOLVED: To provide a mixing data analysis system which enjoys a large degree of design freedom and can cut a design term and design costs. SOLUTION: A particle-tracking analyzing part 3 combines data by interpolation calculation on the basis of discrete flow velocity field data obtained as a result of a heat flow analysis at a heat flow-analyzing part 2, thereby obtaining data on path of particle. A mixing data-evaluating analyzing part 4 calculates for each flow locus line a change of a vector connecting a point on the path of particle and points on a group of path of particles present within a predetermined distance from the point after a predetermined time, obtains a transformation matrix representing the change of the vector by linear approximation, sets as an extension rate of an optional three-dimensional area at the section a maximum component of a specific value corresponding to a maximum extension rate in a specific vector direction of the area transformed by the transformation matrix, repeatedly obtains the extension rate via every predetermined time up to a predetermined position of the path of particle, and indexes a history of mixture along the flow locus lines with an average value of the extension rates.</p> |
