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.
Key Features
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.
Integration
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.
Material Properties
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.
Land-Climate Interactions
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.
Solutions
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.
Surface Energy Balance
This example evaluates the effect of snow on the thermal response within the ground during the winter months, using the surface energy balance boundary condition in TEMP/W to simulate land-climate interactions.
Thermosyphons
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.
