A thermal balance for hardness testing
Journal of Physics E: Scientific Instruments, 1982A technique for the measurement of hardness, through the observation of thermal contact resistance, is described. A heated copper-tipped probe with a small mechanical load is brought down on the test material at the same time as a similar heated probe with a diamond-tip.

Thermal analysis of a balanced calorimeter for testing electrical machines
2011 IEEE Energy Conversion Congress and Exposition, 2011This study investigates the operation of a balanced calorimeter using Computational Fluid Dynamics (CFD) and experimental methods. The analysis focuses on a 30 kW calorimeter for testing electrical machines. The considerations of thermal performance in terms of heat leakage and measures to improve the design are highlighted.
