Steady state experimental investigation of thermal contact conductance between curvilinear contacts using liquid crystal thermography

摘要

Heat transfer components comprise of several types of metallic contacts. Commencing from the conventional conforming rough surface contact combinations, the situation might culminate in terms of the complex non-conforming rough curvilinear contacts of the real heat transfer devices. Available theoretical models fail to correctly predict thermal contact conductance (TCC) over the broader range of influencing parameters, even for the simplest geometry, and thus experiments plays a pivotal role in the field. Researchers are indefatigably working for developing accurate experimental methodologies to get precise estimate of TCC, and create broader database of results for upcoming theoretical models.
