Solar thermal energy receiver [PDF]

open access: yes, 1992
A plurality of heat pipes in a shell receive concentrated solar energy and transfer the energy to a heat activated system. To provide for even distribution of the energy despite uneven impingement of solar energy on the heat pipes, absence of solar ...

Resonant photon tunneling enhancement of the radiative heat transfer [PDF]

open access: yes, 2004
We study the dependence of the heat transfer between two semi-infinite solids on the dielectric properties of the bodies. We show that the heat transfer at short separation between the solids may increase by many order of magnitude when the surfaces are ...

Modelling linered engine blocks [PDF]

open access: yes, 1991
Factors that affect heat transfer in the linered aluminium engine block are examined to determine their importance. Conduction is found to be the dominant mode of heat transfer, and the interface is characterised as imperfect contact if there are no ...

Heat transfer in a recirculation zone at steady-state and oscillating conditions - the back facing step test case [PDF]

open access: yes, 2008
Steady state and transient heat transfer is a very important aspect of any combustion process. To properly simulate gas to wall heat transfer in a turbulent flow, an accurate prediction of the flow and the thermal boundary layer is required.

Trace formulae for non-equilibrium Casimir interactions, heat radiation and heat transfer for arbitrary objects [PDF]

open access: yes, 2012
We present a detailed derivation of heat radiation, heat transfer and (Casimir) interactions for N arbitrary objects in the framework of fluctuational electrodynamics in thermal non-equilibrium.

A Method of Calculating a Time-Varying Volume of Combustion Products in the Cylindrical Chamber

open access: yesМеханика машин, механизмов и материалов, 2008
A method of calculating a volume of combustion products when a flame spreads in the closed cylindrical chamber is developed, assuming that the front is spherical for two positions of an ignition source: at the end (central ignition) and cylindrical (side
