Heat Transfer in Teeth

Journal of Dental Research, 1973
Experiments were conducted to determine the thermal resistance between food and teeth during mastication processes and the drinking of beverages. It was found that the assumption of negligible resistance between food and teeth overestimates greatly the resulting temperature gradients.

Heat Transfer Capability of Ionanofluids for Heat Transfer Applications

International Journal of Thermophysics, 2020
Ionanofluids are mixtures of ionic liquid and solid particles with enhanced thermo-physical properties. Using the properties of these ionanofluids (thermal conductivity, dynamic viscosity, specific heat, and density), a comprehensive analysis concerning their heat transfer capability was performed.

Heat Transfer (Planetary)

2011
In planetary interiors, heat is generated by the decay of the ▶ radiogenic isotopes U, U, Th, and K. In addition, latent heat may be released and consumed through phase transitions. The dissipation of kinetic energy of ▶ planetesimals colliding with the protoplanets during planetary accretion has heated the planetary interiors, in some cases up to the ...

Bistable Heat Transfer in a Nanofluid

Physical Review Letters, 2009
Heat convection in water can be suppressed by adding a small amount of highly thermophilic nanoparticles. We show that such suppression is not effective when a suspension with uniform concentration of nanoparticles is suddenly heated from below. At Rayleigh numbers smaller than a sample dependent threshold Ra;{*} we observe transient oscillatory ...

Heat Transfer Spectroscopy and “Heat Transfer-Distance” Curves

Volume 13: Nano-Manufacturing Technology; and Micro and Nano Systems, Parts A and B, 2008
Thermal radiative transfer between objects as well as near-field forces such as van der Waals or Casimir forces have their origins in the fluctuations of the electrodynamic field. Near-field radiative transfer between two objects can be enhanced by a few order of magnitude compared to the far-field radiative transfer that can be described by Planck’s ...

Vortices and Heat Transfer

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1997
AbstractFor internal flow the influence of vortices on heat transfer is studied mainly numerically. Laminar channel flows with two types of periodic vortex generators (VGs), transverse ribs and rectangular winglets, are considered. The transverse ribs generate transverse vortices (TVs), and the rectangular winglets at 45° angle of attack generate ...

Heat Transfer Effectiveness of Heat Pipes

Journal of Heat Recovery Systems, 1982
Abstract Heat transfer effectiveness (recovery factor), HTE, of one heat pipe, HP, is defined as the function of two dimensionless groups of NTU type (number of transfer units) from the] evaporator and the condenser. In the case of the HP heat exchanger it is demonstrated that the HTE is a function made up of only three elements, viz; the HTE of the ...

A feature of heat transfer to organic heat-transfer media

Journal of Engineering Physics, 1986
It is shown that the nature of the changes in the wall temperature during heat transfer to an organic heat-transfer medium accompanied by the formation of deposits depends strongly on the roughness of the surface.
