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,

Tyre–Road Heat Transfer Coefficient Equation Proposal
Applied Sciences, 2023 Tyres are one of the most important elements of a vehicle because they are the link to the road and have a huge impact on traffic-related pollution. Knowing their behaviour, thus being able to use them at their best and reducing their wear rate, is one ...

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.

Heat Transfer Coefficients in Concentric Annuli [PDF]
Journal of Heat Transfer, 2002 The geometric shape of a passage’s cross-section has an effect on its convective heat transfer capabilities. For concentric annuli, the diameter ratio of the annular space plays an important role. The purpose of this investigation was to find a correlation that will accurately predict heat transfer coefficients at the inner wall of smooth concentric ...

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.
