Modules based on the geochemical model PHREEQC for use in scripting and programming languages
The geochemical model PHREEQC is capable of simulating a wide range of equilibrium reactions between water and minerals, ion exchangers, surface complexes, solid solutions, and gases. It also has a general kinetic formulation that allows modeling of nonequilibrium mineral dissolution and precipitation, microbial reactions, decomposition of organic compounds, and other kinetic reactions. To faci...
متن کاملPHT3D: a reactive multicomponent transport model for saturated porous media.
This column reviews the general features of PHT3D Version 2, a reactive multicomponent transport model that couples the geochemical modeling software PHREEQC-2 (Parkhurst and Appelo 1999) with three-dimensional groundwater flow and transport simulators MODFLOW2000 and MT3DMS (Zheng and Wang 1999). The original version of PHT3D was developed by Henning Prommer and Version 2 by Henning Prommer an...
متن کاملPHT3D – A MODFLOW/MT3DMS-based reactive multi-component transport model
PHT3D, a three-dimensional, MODFLOW/MT3DMS-based reactive multicomponent transport model is presented. The model couples, via an operator-splitting method, the transport simulator MT3DMS (Zheng and Wang, 1998) and the geochemical package PHREEQC-2 (Parkhurst and Appelo, 1999). Through the flexible, generic nature of PHREEQC-2, PHT3D can handle a broad range of equilibrium and kinetic reactive p...
متن کاملA critical study of David Ross’s view on ethical mutual competitions with an emphasis on religious texts
This paper has studied David Ross`s solutions for ethical mutual competitions. For Ross, the mutual competition happens in ethical duty of the present, and one should give priority to those duties with more emphasized obligation. He has considered special relationship as the foundation for ethical duties upon which the norm for priority and the degree of obligation are based. As is understood b...
متن کاملAPG: An Efficient Software Program for Amp-Pl Thermobarometry Based on Graphical Method
Geothermobarometry equations are based on thermodynamic principles and appear in single or multi-variant functions. The number of variants for a specific composition or reaction usually is reduced into 2 involving temperature (T) and pressure (P). Since most of planned equations have two passive or variant P and T, using these equations should be with special care. It is very effective to use g...
