The Effect of Sorption/Curved Interface Thermodynamics on Pressure Transient

Abstract

A simulation model capable of handling the effects of sorption was constructed. It accounts for the curved interface thermodynamics associated with adsorption and desorption. Data from several laboratory experiments were used to verify the model. The results indicated that simulation runs using sorption isotherms adequately model the pressure transient behavior observed in the laboratory experiments. Dry steam models severely underestimated the the effective compressibility. Models using flat-interface (steam table) thermodynamics over-estimated the compressibility of the system, indicated by slower than actual rate of pressure transient propagation.
