To examine conduction heat transfer let us, for instance, look at the steady-state heat transfer rate, Q· (W), through the solid electrolyte layer thickness, Δx, which is a function of the hot fluid temperature, TH, and cold fluid temperature, TC, the geometry and property are given ...
The modified packet model for heat transfer between a gas-fluidized bed and an immersed surface is presented. In contrast to the model of Mickley and Fairbanks, allowance was made for the effective gap heat resistance between the packet of particles and surface (the contact thermal resistance Rk...
Part 1 deals with single-medium transfer, specifically with intraphase transfers in single-phase flows and with intramedium transfers in two-phase flows. Part 2 deals with fluid-solid transfer processes, both in cases where the interface is small and in cases where it is large, as well as ...
The flow domain displayed a stable core region and the average core temperature was found to be strongly influenced by different stacking arrangement of solid objects. In general, the staggered arrangement resulted in lower heat transfer through the surfaces which is linked with the suppression of ...

Heat transfer in solids is typically conducted through either electrons or atomic vibrations known as phonons. In a vacuum, heat has long been thought to be transferred by radiation but not by phonons because of the lack of a medium1. Recent theory, however, has predicted that quantum fluctuati...

Temperature and temporal dependences of radiative heat transfer. a HTP between two graphene nanodisks (20 nm diameter, 0.2 eV Fermi energy, d = 1 nm separation) as a function of T 1 and T 2 for the geometry of Fig. 1. Black solid curves represent the evolution of the elec...
With ordinary surfaces, the flow may be affected by different methods: gas bubble mixing in the liquid flow and solid particle or liquid drop mixing in the gas flow, heat transfer surface rotation, surface vibration, heat carrier pulsations, flow affected by electrostatic fields, and flow suction...
