Measurement of the Convective Heat-Transfer Coefficient [PDF]
The Physics Teacher, 2014 We propose an experiment for investigating how objects cool down toward the thermal equilibrium with their surroundings. We describe the time dependence of the temperature difference of the cooling objects and the environment with an exponential decay function.

Determination of the convective heat transfer coefficient [PDF]
Dental Materials, 1987 The value of the convective heat transfer coefficient (htc) is determined under different loading conditions by using a computer aided method. The thermal load has been applied mathematically as well as experimentally to the coronal surface of an axisymmetric tooth model.

Convective Heat Transfer Coefficients in the Circulation [PDF]
Journal of Biomechanical Engineering, 1991 Convective heat transfer in the vessels of the circulatory system is investigated numerically. In the modeling, account is taken of the non-Newtonian rheological properties of blood and the presence of a cell-depleted plasma layer at the vessel wall. The latter is found to produce a remarkable enhancement of the heat transfer rate in the small vessels,

On the scaling of convective boiling heat transfer coefficient
International Journal of Heat and Mass Transfer, 2021 Abstract Flow boiling has been widely used during the last century, but the key mechanisms controlling the heat transfer process still remain elusive. In the particular case of convective flow boiling inside a heated pipe, most of the existing correlations have been proposed assuming an enhancement factor to the liquid Reynolds number.

Convection Heat Transfer Coefficients in Thermoacoustic Heat Exchangers: An Experimental Investigation [PDF]
Energies, 2019 This paper investigates the thermal performance of thermoacoustic heat exchangers subjected to acoustically oscillating flows. The analysis is carried out by experimental measurements of the heat fluxes sustained by the ambient heat exchanger of a prime mover of the standing wave type.

Spectral Heat Transfer Coefficient for convection
International Journal of Heat and Mass Transfer, 2023 The present work is aimed at developing a methodology to predict convective heat transfer of flow bounded by a non-isothermal wall, which has been a long-standing issue of interest for Newton's law of cooling. A framework is proposed to centre around the Spectral Heat Transfer Coefficients (SHTC).

Case Studies in Thermal Engineering, 2023 On the basis of the conjugate gradient method, an inversion model of the transient convective heat transfer coefficient between the bore surface and the gunpowder gas is presented. In this study, the measured temperature at a certain depth from the bore surface is employed as input.
