POROUS BODY, HONEYCOMB FILTER AND MANUFACTURING METHOD FOR POROUS BODY
Porous body data 60 where position information and type information are correlated by CT scan is created. Based thereupon, multiple virtual curved surface solids made up of parent virtual spheres and child virtual spheres are placed so as to fill in space pixels with curved surface solid pixels occupied by the virtual curved surface solids, based on the porous body data 60, and fluid analysis is performed regarding the porous body data 60 (S100 through 110) and microstructure analysis is performed (S120 through S160). The porous body at this time satisfies at least one of the following three conditions; "the average value of multiple in-plane uniformity indices ³ X is 0.6 or greater, and the spatial uniformity index ³ is 0.6 or greater", "the percentage of the total value of volume of low-flow-velocity curved surface solids as to the total value of volume of multiple virtual curved surface solids is 20% or less, and the percentage of the total value of volume of high-flow-velocity curved surface solids as to the total value of volume of multiple virtual curved surface solids is 10% or less", and "the percentage of the total value of volume of mid-diameter curved surface solids as to the total value of volume of multiple virtual curved surface solids is 60% or more".
