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 ...

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.

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

Analytical Definition Of The Overall Heat Transfer Coefficient

SPE California Regional Meeting, 1979
Abstract It is a well-known fact that the solution of many problems connected with heat transfer in porous media problems connected with heat transfer in porous media can be simplified efficiently by using the overall heat transfer coefficient concept to represent the heat loss from a reservoir into the adjacent ...

In – line determination of heat transfer coefficients in a plate heat exchanger

2009
This paper shows an in – line determination of heat transfer coefficients in a plate heat exchanger. Water and aqueous working solution of lithium bromide + ethylene glycol are considered. Heat transfer coefficients are calculated for both fluids. “Type T” thermocouples were used for monitoring the wall temperature in a plate heat exchanger, which is ...

Heat transfer in a tunnel pasteuriser. Part II: Heat transfer coefficients

Journal of Food Engineering, 1984
Abstract The effect of heat transfer resistances on the overall heat transfer between water spray and liquid heated in a glass container has been studied. Values for convective and overall heat transfer coefficients were determined. The overall heat transfer coefficient was affected by hot water spray intensity, location of bottle in relation to the ...

DETERMINATION OF THE HEAT TRANSFER COEFFICIENT DURING CONVECTION HEAT TRANSFER

Power Engineering Problems
The article is devoted to determining the heat transfer coefficient during convective heat transfer. Convective heat transfer or heat transfer is the process of heat transfer between the surface of a solid and the surrounding medium (gas or liquid). In this case, heat transfer occurs due to the combined action of thermal conductivity and convection ...
