The following verification test case compares the results from The Thermal Wizard calculation to a numerical simulation using MAYA's TMG Thermal Analysis software. The input values and results are shown below.
|Inner Radius||0.05 meters|
|Temperature at Inner Surface||100 oC|
|Heat Flow from Inner to Outer Surface||25 W|
|Layer 1 Thickness and Conductivity||0.01m and 3.5 W/m2C|
|Layer 2 Thickness and Conductivity||0.01m and 0.8 W/m2C|
|Layer 3 Thickness and Conductivity||0.03m and 0.1 W/m2C|
Comparison of Results
|The Thermal Wizard
Tn = 74.7 oC
|MAYA TMG Thermal Analysis
Tn = 74.6 oC
Below is a contour plot showing temperatures. The inner temperature (hottest) is 100C and the outer temperature is 74.6 oC.
