POROUS BODY, HONEYCOMB FILTER, METHOD FOR PRODUCING POROUS BODY, AND METHOD FOR PRODUCING HONEYCOMB FILTER
A porous body constituting a porous partition wall 44 of a honeycomb filter 30 has a porosity P of 20% to 60%, a permeability k of 1 μm2 or more and satisfies k≧0.2823 P−10.404. The porous body is obtained by a method for producing, for example, includes (a) a step of acquiring porous body data representing a temporary porous body having porosity higher than target porosity, (b) a step of deriving information about a flow rate for each space voxel during passage of a fluid through inside of the porous body, (c) a step of preferentially replacing the voxel having a low flow rate among the space voxels with the object voxel, and adjusting the porosity of the porous body data to the target porosity, and (d) a step of forming a porous body based on the porous body data after replacement.
