Numerical Simulation Of Heat And Liquid Transfer In The Hydrothermal Ore-forming Progresses

Dynamics of the hydrothermal ore-forming progresses is to study thehydrothermal progress, the altering reaction between the hydrothermal liquid and thesurrounding rocks, and the crystallization rate and mechanisms of the ore metalsbased on the geologic-geochemistry study of the classic hydrothermal deposits, it is avery important academic direction of the ore-forming theory. Hydraulic fracturing, aimportant way of releasing pressure of over pressured fluid, is becoming to befocused on by more and more domestic and foreign professors in these years, becauseof being closely related with the hydrothermal ore-forming.At the aspect of the mathematic modeling of hydraulic fracturing, given that thevolatile constitutes became gas state from bean-like critical state, this journal, basedon the summaries of the former results and the fact that the over-pressured fluiddegases with decreasing of the pressure and temperature, dissolves the mixed gas'spressure in the close system with the Vander Walls formula.At the aspect of dynamics of the ore-forming progresses, the journal details themathematic model with the theory of dynamics of the ore-forming progresses, anddissolves it with triangulation, one-dimension finite difference method and Galerkinfinite element under two dimensions. And the journal applies the model with the dataof the Jin Ding deposit to detail the distribution and change of the temperature, theflow velocity, and the metallogenetic elements in the mineralization at the view ofdynamics.
