Heat transfer analysis
TEMP/W is a powerful finite element software product for modeling heat transfer and phase change in porous media. TEMP/W can analyze simple conduction problems to complex surface energy simulations with cyclical freeze-thaw.
Add TEMP3D to TEMP/W to analyze 3D heat transfer using the same comprehensive set of material models and boundary conditions.
TEMP/W and TEMP3D offer a range of boundary condition options, including a rigorous thermosyhpon boundary condition. The convective heat transfer boundary condition allows for simulation of artificial ground freezing or other processes involving the fluid flow over a bounding surface.
Heat transfer is often governed by forced convection in natural hydrogeological systems. TEMP/W can be fully-integrated with SEEP/W or AIR/W to analyze heat transfer via groundwater flow or air flow, respectively. Integration of TEMP3D and SEEP3D is also available.
Thermal functions defining the material properties for saturated-unsaturated soils can be estimated using built-in functions. The rigorous phase change formulation provides an accurate solution to problems involving freeze-thaw of saturated-unsaturated porous media.
Analyze problems that involve a coupling between climatic conditions and the thermal response within the ground in TEMP/W using the surface energy balance boundary condition.
TEMP/W and TEMP3D can model almost any geothermal problem
Freezing Analysis of a Buried Pipeline
TEMP/W is used to model the freezing front propagation around a pipeline. The examples demonstrates the use of circular regions and the application of the appropriate boundary conditions and material properties.
The objective of this TEMP/W example is to conduct a transient analysis of thermosyphons installed near Fairbanks, Alaska. The model is assumed to have permafrost year round at the base. A heated building rests on the ground surface.
3D Mine Shaft Freezing
This example demonstrates a procedure for modeling the freeze wall growth for a mine shaft project using freeze pipes installed at equal distances around a mine shaft. Particular attention is given to the three-dimensional heat transfer at the bottom of the freeze wall.
