โฆ Synopsis
tricity of the heater and thermometer in the test section, a teledeltos paper model was made simulating the boundary conditions. It was found that no more than 0"3% variation from isothermality was caused by asymmetry. The final analysis was performed to determine heat losses through the epoxy ends, using a one-dimensional pin fin model. No more than 0"8% of the total energy dissipated in the heater was lost out the ends.
Advantages of this type of test section are: ample room for multiple specimens in a single dewar, short down-time between experiments, ease in fabrication, and accuracy. Kapitza resistance data was obtained from this type of test section and reported by Goodling and Irey. 3 The data are in good agreement with other investigations.
