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,

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.
