SVOffice™ 2009 Professional Coupling

The Professional version of each SVOffice™ 2009 software package gives you the capability to fully couple your model with other packages. Coupling allows the solution of multiple processes within the context of a single modeling problem. Click here to learn more about all available SVOffice™ 2009 software coupling options.

Borehole Thermal Extraction Systems (BTES)

One potential use of the coupled SVFlux™ and SVHeat™ Professional software packages is the analysis of geothermal systems. There has been recent focus on the performance of geothermal systems in the industry as an alternative energy source. One aspect of geothermal systems is pumping heat into large underground aquifers and then extracting that heat at a later time and/or a later position in the aquifer. This concept shows promise but for it to work properly there must be a mechanistic understanding of the processes involved. A 2D or 3D numerical model of such a system provides an excellent way to predict possible performance.

When heat is injected into the upstream area of the aquifer there is a buoyancy effect which takes place because of the hot liquid. Therefore the tendency of the heated water is to flow along with the groundwater as well as rise to the top surface of the aquifer. This tendency can be replicated in the numerical SVFlux™ and SVHeat™ coupled model. The coupled software solves for both convective and conductive heat flow. The software also implements injection and extraction wells for the estimation of water and heat flows for different rates and temperatures of injection. Summaries of total energy contained in the aquifer system can be produced over time. Heat flow in and out of the aquifer can also be reported as a function of time.

Air and Thermal Coupling


Air flow magnitudes and directions

SoilVision systems Ltd. is pleased to announce the addition of full air and thermal coupling between the SVAirFlow® and SVHeat® Professional software packages. This addition extends the capabilities of the software to model flow of air in the pore space of soils. In particular, the flow of air as a result of thermal gradients can be accomplished. This addition allows benefits in modeling the following applications:

  • Heap leaching: certain heap leaching operations consume oxygen during the reaction process. There is therefore the danger that the reactions will become oxygen starved and extraction will not reach capacity. Therefore air injection systems are sometimes introduced to enhance recovery. The performance of such systems can be modeled with the combined SVAirFlow® and SVHeat® software packages.
  • Convective air flow in embankments: thermal convection in her embankments can now be modeled (Goering, 2003)
  • Waste rock air movement: the reactions in many waste rock piles often produce heat which then affects the flow of air in such piles. The numerical modeling of such a process can aid in the long-term design of remediation scenarios for waste rock piles.
