Dynamic effects on capillary pressure-saturation relationships for two-phase porous flow: implications of temperature
journal contribution
posted on 2014-10-30, 14:22 authored by Navraj S. Hanspal, Diganta DasDiganta DasWork carried out in the last decade or so suggests that the simulators for multiphase flow in porous media should include an
additional term, namely a dynamic coefficient, as a measure of the dynamic effect associated with capillary pressure. In this work,
we examine the dependence of the dynamic coefficient on temperature by carrying out quasi-static and dynamic flow simulations for
an immiscible perchloroethylene–water system. Simulations have been carried out using a two-phase porous media flow simulator
for a range of temperatures between 20 and 80
C. Simulation domains represent 3-D cylindrical setups used by the authors for
laboratory-scale investigations of dynamic effects in two-phase flow. Results are presented for two different porous domains, namely
the coarse and fine sands, which are then interpreted by examining the correlations between dynamic coefficient(s) and
temperature, time period(s) required for attaining irreducible water saturation, and the dynamic aqueous/nonaqueous phase
saturation and capillary pressure plots. The simulations presented here maintain continuity from our previous work and address the
uncertainties associated with the dependency of dynamic coefficient(s) on temperature, thereby complementing the existing
database for the characterization of dynamic coefficients and subsequently enabling the users to carry out computationally
economical and reliable modeling studies.
