PetraSim 水流、运移、热建模软件
PetraSim是一个用于TOUGH2仿真器的图形界面,它可以用于解决与地热系统、碳封存、多相污染物运输等相关的问题。
产品介绍
利用PetraSim解决具有挑战性的地下水流问题。
PetraSim是一个用于TOUGH2仿真器的图形界面,它由Lawrence Berkeley National Laboratory开发。流体在孔隙和裂隙介质传热中,TOUGH2和它的软件具有强大的模拟功能。TOUGH2代码解决的问题包括从Yucca山地下水流到多元环境整治等。PetraSim通过一个交互式的3D环境,使建模者能够访问TOUGH2的功能,包括网格生成、参数定义和结果显示。
PetraSim降低了使用TOUGH2的难度,让分析师专注于模型,同时自动处理TOUGH2输入和输出文件复杂的细节。
Petrasim包含TOUGH2(v2),
T2VOC,TMVOC和 TOUGHREACT(v1.2)执行文件。也支持TOUGH 2.1和TOUGHREACT 2.0,但是需要额外付费购买。此外,还支持HydrateResSim,必须从NETL获取,才能与PetraSim一起使用。PetraSim还包含了对TOUGHREACT v3.0和TOUGHREACT-Pitzer的部分支持。
使用PetraSim自带的TOUGH2 v2可执行文件,包括了只有PetraSim才能修改的源代码。包括CSV文件的输出(用于界面中的结果可
视化)和一些旨在改进地热模型的更改。
All EOS module executables are optimized and integrated into PetraSim, so no further compilation is required. The user clicks and runs. If you have developed a modified variation of TOUGH, support is provided to pre-process and post-process those results also.
T2VOC is a TOUGH2 module for 3-phase flow of water, air, and a volatile organic compound (VOC). T2VOC was designed to simulate processes such as the migration of hazardous non-aqueous phase liquids (NAPLs) in variably saturated media, forced vacuum extraction of organic chemical vapors from the unsaturated zone (soil vapor extraction), evaporation and diffusion of chemical vapors in the unsaturated zone, air injection into the saturated zone for removal of volatile organics (air sparging), direct pumping of contaminated water and free product, and steam injection for the removal of NAPLs from contaminated soils and aquifers.
PetraSim supports the following models:
TOUGH2 is a general-purpose numerical simulation program for multi-phase fluid and heat flow in porous and fractured media. It belongs to the MULKOM family of codes, developed in the Earth Sciences Division of Lawrence Berkeley National Laboratory for applications in geothermal reservoir engineering, nuclear waste disposal, and unsaturated zone hydrology.
EWASG (included in the TOUGH2/T2VOC module) has been developed within the frame of a collaboration among Aquater , an engineering services company of the Eni Group (now incorporated into Saipem ), the International Institute for Geothermal Research (IIRG) (now incorporated into the Institute of Geosciences and Earth Resources (IGG) of the National Research Council of Italy (CNR)) and the Earth Sciences Division (ESD) of Lawrence Berkeley National Laboratory (LBNL). Geothermal fluids usually consist of complex mixtures of water, salts and gases. As the thermodynamic and transport properties of such mixtures affect reservoir conditions and performance, the EWASG (Equation-of-state for WAter, Salt and Gas) module has been developed for the TOUGH2 multipurpose numerical reservoir simulator to handle three-component fluid mixtures of water, sodium chloride and a slightly soluble non-condensible gas (NCG).
