Aluminum Oxide Nanofluid Energy Transfer
Nanofluid is a new class of heat transfer fluids engineered by dispersing metallic or non-metallic nanoparticles with a typical size of less than 100 nm in the conventional heat transfer fluids.This article aims to investigate the overall and convection heat transfer coefficient and Nusselt number of Al2O3-water nanofluid flowing in a horizontal double pipe heat exchanger under turbulent flow (...
متن کاملRadiative Energy Transfer with Filter
An ideal blackbody resides inside a cavity in a medium of temperature T that is also an ideal blackbody. If the small black body is initially at temperature T could its temperature evolve to an equilibrium temperature T ′ different from T if the inner surface of the cavity is covered with a passive filter? For example, the filter might be an ideal transmitter for light of wavelength λ < λf (or ...
متن کاملEnergy Transfer to Optical Microcavities With Waveguides
Micro/nanoscale radiation energy transfer is investigated in optical microcavity and waveguide coupling structures working on whispering-gallery mode optical resonances. The finite element method is employed for solving the Helmholtz equations that govern the energy transfer and time-harmonics electromagnetic (EM) wave propagation. The maximum element size concept is introduced for the numerica...

متن کاملEnergy Transfer Upconversion
The usual fluorescence behavior follows Stokes law, where exciting photons are of higher energy than emitted photons. Anti-Stokes processes usually concern emitted energies in excess of excited energies by only a few kT. These processes include anti-Stokes emission by the thermal bands or by the Raman effect. There are processes, however, in which emission photon energy exceeds excited photon e...
