Development of an ASTM standard steady-state characterization platform for bulk and interface thermal resistance measurements
Project Description
For many materials and device development applications, accurate characterization of the thermal transport properties is important. Among multiple ASTM standard methodologies, the steady-state "cut bar" technique provide advantages such as easy installation, convenient implementation and straightforward analysis. This project is to design and fabricate a simple heat transfer measurement device based on the ASTM-D5470 protocol to facilitate the study of bulk materials and interface thermal resistance of samples.

Applicant's Roles
Working with the PG students, the applicant should study the principles of steady-state heat conduction and the corresponding thermal conductivity measurement (especially how to minimize the heat loss and to approximate 1D heat flow), design the apparatus, manufacture the device parts by machining and 3D printing coupled with the positioning of temperature sensors and heat source, and finally assemble the parts and test the apparatus to conduct with data acquisition and analysis. Parasitic heat loss by convection and radiation shall be minimized with thermal insulation methods.
