GAS-LIQUID TWO-PHASE FLOW EVALUATION SIMULATION DEVICE AND GAS-LIQUID TWO-PHASE FLOW EVALUATION SIMULATION PROGRAM

摘要

PPROBLEM TO BE SOLVED: To perform calculation giving excellent compatibility with an experiment result when the porosity distribution of a porus body has a plurality of porosity peaks, in gas-liquid two-phase flow evaluation simulation. PSOLUTION: When the porosity distribution of the porus body has the plurality of porosity peaks, the porus body is modeled as a porus body wherein each layer having the porosity distribution corresponding to each the porosity peak is sequentially layered and disposed (S10), a gas relative permeability kSBG/SBand a liquid relative permeability kSBL/SBare respectively calculated according to the porosity distribution in each the layer (S12), an inflow pressure PSBIN/SBis imparted to a first layer to obtain PSBOUT1/SBon an outflow pressure side of the first layer (S14), the outflow pressure PSBOUT1/SBof the first layer is imparted as an inflow pressure PSBIN2/SBto a second layer to obtain an outflow pressure PSBOUT2/SBof the second layer (S16), and it is repeated to calculate a pressure loss P of the porus body with an outflow pressure obtained about an outflow side layer as PSBOUT/SB(S20).
