Description
A uniform infinite slab of liquid is considered to be initially at zero degree temperature. Suddenly, the temperature of the surface x = 0 is reduced to -45 F and maintained constant. Calculate the temperature distribution in the slab and the time variation (response) at x = 1".

Study Type
Transient thermal analysis.
Shell Parameters
Shell thickness = 1" - Thin formulation.
Meshing Parameters
Use a Global Size of 0.1".
Material Properties
Density = 1 lb/in3, Thermal conductivity = 1.08 BTU/(in-sec-F). The specific heat of the liquid (C) has the following temperature variation:
Modeling Hints
A zero temperature is initially applied to the model. The study properties are set to Transient with a Total time of 2 sec and 0.1 sec Time increment.
Results
The following response at x = 1" is found to be in good agreement with the results reported in the reference mentioned below.
