Numerical analysis of convective heat transfer coefficient for building facades
Journal of Building Physics, 2018The latest architectural trends demand an extensive use of glazed curtain walls running from building floor to ceiling. While glazing poorly controls the heat flow, it is important for viewing, daylighting, and solar design features. In order to evaluate

Can flow oscillations during flow boiling deteriorate the heat transfer coefficient?
Applied Physics Letters, 2018Two-phase flow instabilities have been identified as one of the impediments for achieving high heat flux in boiling systems due to their potential heat transfer deterioration.

Heat Flux and Heat Transfer Coefficient
2021Heat flux and heat transfer coefficient may either be measured by a single measurement process, or they may require the measurement of several quantities before they may be estimated. Of course, it is best if the required quantity is directly measurable. We will give as much detail as possible, keeping in mind the target reader of the book.

Heat Transfer Engineering, 2021
One of the main disadvantages of conventional fixed-bed adsorption chillers is the low coefficient of performance due to the high voidage of the sorbent beds.

Bulk transfer coefficient for heat transfer
Journal of Geophysical Research, 1969A 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
2017The 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
2013In 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.

The heat transfer equation with an unknown heat capacity coefficient
Sibirskii zhurnal industrial'noi matematiki, 2020Under 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).
