Sensitivity of the Heat-Transfer Coefficient Calculation [PDF]
Materials Performance and Characterization, 2014 AbstractThe purpose of the Liščić/Petrofer probe is to determine the cooling intensity during liquid quenching in laboratory and workshop environments. The surface heat-transfer coefficient is calculated by the one-dimensional finite-volume method from the smoothed temperature curve, measured at a near-surface point in the probe.

Thermal conduction in two-dimensional complex plasma layers [PDF]
Physics of Plasmas 28, 010704 (2021), 2021 A simple vibrational model of heat transfer in two-dimensional (2D) fluids relates the heat conductivity coefficient to the longitudinal and transverse sound velocities, specific heat, and the mean interatomic separation. This model is demonstrated not to contradict the available experimental and numerical data on heat transfer in 2D complex plasma ...
