Unformatted text preview: Assumptions and Modeling Notes
The thermal analysis, which solves the Laplace equation, is used to solve this problem since the seepage flow is
also governed by the Laplace equation. The following mental substitution of input and output variables (thermal
: flow) are used:
• (temperature : flow potential (or pressure head)) • (heat flow rate : fluid flow rate) • (thermal conductivity : permeability coefficient) ANSYS Verification Manual . ANSYS Release 9.0 . 002114 . © SAS IP, Inc. 1–360 VM163
The bottom and side of the model are assumed to be far enough away from the caisson to be treated as impermeable. Results Comparison
