Heat Transfer Capability of Ionanofluids for Heat Transfer Applications
International Journal of Thermophysics, 2020Ionanofluids 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.

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.

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 ...

Bistable Heat Transfer in a Nanofluid
Physical Review Letters, 2009Heat 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 ...

Temperature highly affects pavement performance. High and low temperatures not only affects the viscosity of asphalt concrete but also has an impact on the moisture flow within pavements. At temperatures below 0°C the freezing of pavements dramatically changes the permeability and frost action might occur forcing water to flow upwards to the freezing ...

HEAT TRANSFER IN THE SEVENTIES
Proceeding of International Heat Transfer Conference 5, 1971The survey reported herein has been conducted under the auspices of the National Science Foundation whose support is gratefully acknowledged. This survey has been made possible through the cooperation of the many persons whose advice I sought and who have responded most generously by supplying information and offering suggestions.

Heat Transfer Spectroscopy and “Heat Transfer-Distance” Curves
Volume 13: Nano-Manufacturing Technology; and Micro and Nano Systems, Parts A and B, 2008Thermal 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 ...

A feature of heat transfer to organic heat-transfer media
Journal of Engineering Physics, 1986It 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.

Heat Transfer Effectiveness of Heat Pipes
Journal of Heat Recovery Systems, 1982Abstract 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 ...
