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.

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 ...

Generalization of the heat transfer coefficient concept

2008 Second International Conference on Thermal Issues in Emerging Technologies, 2008
The convection heat transfer coefficient h is a concept that is heavily used by all thermal engineers to solve practical problems. It allows them to approximately analyze complicated systems, without having to systematically perform detailed 3D simulations of all parts of any real system, which is always highly complicated. At least in the first design

Heat transfer coefficient of porous copper with homogeneous and hybrid structures in active cooling

Journal of Materials Research, 2013
Heat transfer coefficients of porous copper samples with single- and double-layer structures, fabricated by the lost carbonate sintering process, were measured under forced convection conditions using water as the coolant. Compared with the empty channel,
