Numerical Simulation of Convective Heat and Mass Transfer in a Two-Layer System
NEW TRENDS IN FLUID MECHANICS RESEARCH: PROCEEDINGS OF THE FIFTH INTERNATIONAL CONFERENCE ON FLUID MECHANICS(2007)
摘要
The results are presented of mathematical and computer modeling of natural convection in the "liquid-gas" two-layer system, filling a vertical cylinder surrounded by solid heat conductive tract. The model describes approximately the conjugate heat and mass transfer in the underground oil product storage, filled partially by a hydrocarbon liquid, with natural gas layer above the liquid surface. The geothermal gradient in a rock mass gives rise to the intensive convection in the liquid-gas system. The consideration is worked out for laminar flows, laminar-turbulent transitional regimes, and developed turbulent flows.
