Bulk transfer coefficient for heat transfer

Journal of Geophysical Research, 1969
A bulk heat-transfer relation applicable to unstable conditions is proposed. The relation incorporates the assumptions that heat transfer near the surface is by molecular conduction, and the bulk transfer relation does not depend explicitly on the surface roughness characteristics, provided that roughness elements are not large in comparison with the ...

Measurement of the Heat Transfer Coefficient

2017
The design of the experimental apparatus and the data collection procedure are discussed. The variation of Rayleigh number, Peclet number, Darcy number, dimensionless height ratio, and dimensionless heater length are accounted for in the design of the experimental apparatus.

Mass and heat transfer coefficients

2013
In a blood oxygenator, the blood spends approximately 2 s passing through the device. Estimate a minimum value for h m , the mass transfer coefficient characterizing oxygen transport from the plasma to the inside of a red blood cell (RBC), such that the RBCs are completely (i.e.

Determination of the stress jump coefficient, the interstitial heat transfer coefficient and the interface heat transfer coefficient in a porous composite system

International Journal of Heat and Mass Transfer, 2017
Abstract In this work, the microscopic and macroscopic models of the porous composite system are established to study the stress jump coefficient, the interstitial heat transfer coefficient and the interface heat transfer coefficient under the local thermal non-equilibrium condition.

The heat transfer equation with an unknown heat capacity coefficient

Sibirskii zhurnal industrial'noi matematiki, 2020
Under study are the inverse problems of finding, together with a solution u(x,t) of the differential equation cut − Δu + a(x, t)u = f(x, t) describing the process of heat distribution, some real c characterizing the heat capacity of the medium (under the assumption that the medium is homogeneous).

Measurement of Heat Transfer Coefficients

2013
In this chapter, measurements of steady-state Nusselt numbers in superposed fluid-porous layers with η < 1 and δ < 1 are discussed and compared to computed values. These measurements point to the need for more exhaustive experimentation over an extended range of Rayleigh number, but they also provide entirely new data for that case where δ < 1 and η ...

Heat Conduction at a Variable Heat-Transfer Coefficient

High Temperature, 2019
Some practically important problems of unsteady heat conduction with a time-variable relative heat-transfer coefficient are considered. Various approaches to finding a solution to the analytical problem are systematized: decomposition of the generalized integral Fourier transform, the serial expansion of a sought temperature function, and the reduction

Heat transfer coefficient of a snow bag

International Journal of Refrigeration, 2002
Abstract In snow shooting, pressurised liquid carbon dioxide is injected via a lance into a permeable snow bag mounted near the ceiling of an insulated transport container. The decrease in pressure causes the liquid carbon dioxide to convert to “snow” and vapour inside the snow bag. The snow bag acts as a phase separator, allowing the sublimated snow

Heat Transfer Coefficients for Finned Exchangers

Industrial & Engineering Chemistry, 1959
The effect of the number of staggered rows on the mean outside heat transfer coefficient for air flowing across extended surface tubes (finned tubes) has been determined experimentally. When the heat transfer coefficient is reported as a function of the Reynolds number, both the power to which the Reynolds number is raised and the constant of ...
