Thermocouple influence on heat transfer coefficient measurement.

Number: 0614

Author(s) : RAPTA P., HEJCIK J., JICHA M.

Summary

This paper investigates the influence of thermocouple installation on the measurement of heat transfer to the reciprocating compressor cylinder wall. The research employs simulations and experimental data to evaluate various aspects of thermocouple installation, focusing on how different mounting methods affect the accuracy of surface temperature measurements. Results indicate that while thermocouple mounting methods do influence surface temperature values, these differences are significantly smaller than the thermocouple resolution, making them difficult to detect in practical measurements. The study also highlights that variations in the calculated Heat Transfer Coefficient (HTC) depend heavily on the HTC evaluation process, which requires improvement for more accurate assessments.
