PRESSURE LOSS ANALYTICAL METHOD, PROGRAM FOR THE SAME, AND PRESSURE LOSS ANALYTICAL DEVICE

摘要

PROBLEM TO BE SOLVED: To analyze a pressure loss by simulating an accumulation state of particulate matters with improved accuracy.;SOLUTION: A CPU of an analytical device: derives transitional distribution information showing accumulation distribution of a particulate layer on an inner periphery at an inflow side of a honeycomb structure after a lapse of minute time Δt through a fluid analysis (Step S130); repeatedly derives the transitional distribution information through the fluid analysis taking into consideration the previously derived transitional distribution information (Steps S130 to S150); and finally derives the transitional distribution information showing the accumulation distribution of the particulate layer (Step S160).;SELECTED DRAWING: Figure 5;COPYRIGHT: (C)2017,JPO&INPIT
