Comprehensive and Powerful TEMP/W
is a finite element software product for analyzing thermal
changes in the ground due to environmental changes or due
to the construction of facilities such as buildings or pipelines.
The comprehensive formulation makes it possible to analyze
both simple and highly complex geothermal problems. You can
apply TEMP/W to the geothermal analysis and design of geotechnical,
civil, and mining engineering projects, including facilities
that are subjected to freezing and thawing temperature changes.
TEMP/W is formulated to account for the latent heat associated
with water turning into ice and ice turning into water. The
rate at which the latent heat is absorbed or released is controlled
by an unfrozen water content function. Above the phase change
temperature, all the water is unfrozen. As the temperature
falls below the phase change point, the portion of the water
that remains unfrozen decreases. Complete flexibility in defining
the unfrozen water content function makes it possible to analyze
a wide variety of ground conditions. When linked with SEEP/W
or AIR/W it can consider convective heat transfer if flowing
water or moving air.
Defining
a Geothermal Model
The unique CAD-like technology in TEMP/W allows you to generate
your finite element mesh by drawing regions on the screen.
You can then specify material properties and interactively
apply boundary conditions. Boundary conditions can be automatically
created from imported climate data, thermosyphon properties,
and convective surface data. If you make a mistake, you can
correct it using the Undo command.
Viewing the Analysis Results
Once you have solved your geothermal problem, TEMP/W offers
many tools for viewing results. Generate contours or x-y plots
of any computed parameter, such as temperature, flux, gradient,
latent heat, or net radiation. Gradient vectors show the energy
flow direction and rate. Transient conditions can be shown
by plotting the changing frost front position over time. View
energy flow paths and flux quantities. Interactively query
computed values by clicking on any node, element Gauss region,
or flux section. Then export the results into other applications,
such as Microsoft Excel or Word, for further analysis or to
prepare presentations.
Measured
climate data can be pasted from a spreadsheet into TEMP/W
and used to determine the actual ground surface temperatures
with or without snowpack. TEMP/W will use precipitation data
to accumulate snow depths over the winter. An energy balance
approach is used to calculate ground temperatures beneath
snow and to melt snow during the spring. Link it with SEEP/W
or AIR/W for convective heat transfer analysis.
TEMP/W 2007 is part of GeoStudio 2007, an integrated tool
containing GEO-SLOPE's leading suite of geotechnical modeling
software products: SLOPE/W, SEEP/W, SIGMA/W, QUAKE/W, TEMP/W,
CTRAN/W, AIR/W and VADOSE/W. Using GeoStudio means you can
run all of these products in one environment, creating one
model definition that is shared among all products.
For example, when you create your geometry and material
properties in one product, they are available immediately
in all other products. Your model is stored in one definition
file, which is based on the industry-standard XML format.
Sharing the data lets you run many analyses on the same
problem. You can use the results from one analysis in another,
or import files created by previous versions of the software.
Typical Applications
TEMP/W
can model almost any geothermal problem, including:
Degradation
of permafrost beneath warm buildings or around a warm,
buried pipeline
Development
of a frost bulb around a chilled pipeline
Ground
freezing for soil stabilization, including use of freezing
pipes around mine shafts or thermosyphons on top of earth
dams
Freeze-thaw
action beneath roadways and airport runways
Frost
depth penetration beneath chilled structures such as a
recreational ice surface or a highway during winter
Effectiveness
of various insulation alternatives for reducing freezing
and/or thawing
TEMP/W
is formulated to analyze ground temperature changes, including
the effects of latent heat due to the phase change from ice
to water and from water to ice. The analysis of latent heat
effects makes TEMP/W a powerful software product for analyzing
various ground conditions. TEMP/W uses Gaussian numerical
integration to formulate the element characteristic matrices.
The integration involves sampling the element characteristics
at selected points and summing the sampled values. As a result,
it is possible to use a different material property at each
sampled point, allowing the material properties to vary throughout
the element.
The thermal conductivity of the soil varies with temperature.
TEMP/W accommodates this with a general conductivity function,
making it possible to consider a smooth transition in conductivity
as the temperature changes from thawed to frozen conditions
and vice versa.
When you purchase a TEMP/W 2007 license you also receive a
copy of the TEMP/W Engineering Methodology book, Thermal
Modeling with TEMP/W 2007. This book is not a software
manual but a full-length book that discusses why and how to
model. It does not describe how to use the commands in the
software or which buttons to click - that is provided in detail
in the Online Help. Instead it is about thinking: how to think
before, during and after setting up and solving a model. The
Engineering Methodology book has chapters devoted to:
The
GeoStudio Student Edition is a free product designed as an
aid to learning geotechnical numerical modeling. It is an
ideal teaching tool for university professors both at the
undergraduate and graduate levels.
The software contains limited versions of SLOPE/W, SEEP/W,
SIGMA/W, QUAKE/W, TEMP/W, CTRAN/W, AIR/W and VADOSE/W.
The
GeoStudio Basic Edition is a feature-limited version of
seven products: SLOPE/W, SEEP/W, SIGMA/W, QUAKE/W, TEMP/W,
CTRAN/W and AIR/W. The Basic Edition is ideal for use in
routine engineering practice for the analysis of problems
with limited geometric complexity. While primarily intended
for analyzing the stability of natural and man-made earth
slopes, you can also use GeoStudio Basic for the analysis
of confined and unconfined steady-state seepage problems,
for the analysis of linear-elastic settlement and stress
distribution problems, for the tracking of contaminants
within ground water flow and for the analysis of freeze-thaw
problems.
