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).

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.

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.

MEASUREMENT OF THE HEAT TRANSFER COEFFICIENT IN A THAWING TUNNEL
Journal of Food Process Engineering, 1998ABSTRACT In a convective (air) thawing tunnel designed in the department of Food Engineering at Lund, and previously applied for the thawing of meat, we have measured the heat transfer coefficient using an ice model with a geometry which could be approximated to an infinite slab.

Determination of the surface heat‐transfer coefficient in CE
ELECTROPHORESIS, 2009AbstractA knowledge of the heat‐transfer coefficient, hs, for the external surface of the capillary or the overall heat coefficient, hOA, is of great value in predicting the mean increase in temperature of the electrolyte, ΔTMean, during electrokinetic separations. For CE, traditional indirect methods of determining hs were time‐consuming and tended to

Heat and mass transfer coefficients of viscous spheres
International Journal of Heat and Mass Transfer, 2001Abstract The problem of mass/heat transfer from a viscous droplet is solved by using a finite-difference scheme, and a dual kind of computational grid. The steady-state Navier–Stokes and energy equations for the flow fields inside and outside a viscous sphere in a fluid of different properties are fully solved numerically for Reynolds numbers ( Re ...

A Correlation for Heat Transfer Coefficients in Food Extruders
Biotechnology Progress, 1986AbstractA dimensionless correlation of heat transfer coefficient for heat flow between the extruder barrel wall and extrudate is presented. The standard error of estimate of the correlation is 12.4%. The correlation is useful for the design and scale‐up of food extruders and the design of associated temperature control systems.
