METHOD FOR ANALYZING HONEYCOMB STRUCTURE, AND PROGRAM AND ANALYSIS DEVICE FOR THE SAME

Object information representing a honeycomb structure with a plurality of meshes is obtained, and an inner-wall-surface heat transfer coefficient h s , i.e., a heat transfer coefficient between an inner wall surface of a cell and a fluid, is derived at an arbitrary time t from an analysis start time until the lapse of a predetermined time as follows. First, one of the meshes as a target for derivation of the inner-wall-surface heat transfer coefficient h s is set (S200), and a dimensionless coordinate X* is derived on the basis of position information (X-coordinate) of the set mesh and fluid state information regarding a state of the fluid in the set mesh at the time t (S210) . An inner-wall-surface dimensionless heat transfer coefficient Nu s corresponding to the derived dimensionless coordinate X* is then derived on the basis of the inner-wall-surface dimensionless correspondence information (S220 to 5250) . The inner-wall-surface heat transfer coefficient h s in the mesh set as the derivation target is then derived on the basis of the derived inner-wall-surface dimensionless heat transfer coefficient Nu s (S260).
