摘要： In a porous body, a surface layer thickness Ts takes a relatively small value satisfying P≧0.54 Ts (formula (1)), the surface layer thickness Ts being derived by a microstructure analysis using the porous-body data that is prepared through three-dimensional scanning of a region including a surface (inflow plane 61) of the porous body. Here, P denotes a porosity [%] of the porous body, and 0%

摘要： Plural of virtual curved surface solids, each of which is a curved surface solid formed by a combination of plural of virtual spheres, is placed so as to fill in space voxels, referring to porous-body data in which positional information is associated with voxel-type information (step S100). Information regarding a flow rate for each space voxel when a fluid passes through a porous body is derived by executing a fluid analysis based on the porous-body data (step S110). A flow-rate-weighted mean diameter Ru, which is a weighted average obtained by weighting an equivalent diameter R′i for each virtual curved surface solid with a volume Vi and an average flow rate Ui for each virtual curved surface solid, is derived based an information regarding the virtual curved surface solids and information regarding the flow rate for each space voxel (step S120).

摘要： A method for analyzing a microstructure of a porous body is, for example, a method using porous-body data in which positional information providing a position of a voxel of a porous body obtained by three-dimensional scanning is associated with voxel type information including information that allows determination as to whether the voxel is a spatial voxel representing a space or an object voxel representing an object. This method includes (a) a step of defining an imaginary surface that is in contact with at least one object voxel present on a surface of the porous body, and identifying, as opening-related voxels, spatial voxels that are in contact with the imaginary surface and spatial voxels that continuously lie in a linear direction from the imaginary surface; and (b) a step of analyzing a microstructure of the porous body on a basis of the opening-related voxels.
