The present work is focused on the flow and transfer of heat analysis silver-graphene with a binary mixture ethylene glycol (EG) water (0:100, 20:80 40:60 vol %) based hybrid nanofluids. Flow formulation developed by considering effect magnetic field, stagnation point flow, Joule heating viscous dissipation. Heat exchanger plays an important role because increasing demand for efficient cooling ...

The current study is an attempt to analytically characterize the second law analysis and mixed convective rheology of (Al2O3–Ag/H2O) hybrid nanofluid flow influenced by magnetic induction effects towards a stretching sheet. Viscous dissipation internal heat generation are encountered in as well. mathematical model partial differential equations fabricated employing boundary-layer approximation....

This paper reports a technique for independent observation of nanometer-scale Joule heating and thermoelectric effects, using atomic force microscopy (AFM) based measurements of nanometer-scale temperature fields. When electrical current flows through nanoscale devices and contacts the temperature distribution is governed by both Joule and thermoelectric effects. When the device is driven by an...

Joule heating in single-walled carbon nanotubes CNTs using a quantum mechanical approach is presented in this paper. The modeling is based on the energy transfer between the electrons and both acoustic and optical phonons. In this formulation, only the knowledge of the full energy dispersion relation, phonon dispersion relation, and the electron-phonon coupling potential is required for the cal...

Joule heating is resulted from inevitable volumetric heating when an electric field is applied across conducting media and it would impose limitations to the performance of electrokinetic microfluidic devices. In this paper, the Joule heating and its effects on electroosmotic flow (EOF) in PDMS microfluidic channels are reported. 3D numerical simulation of the Joule heating induced temperature ...

In this paper, the thermo-electro-structural coupledfield in a cracked metal plate is studied using the finite element analysis. From the computational results, the compressive stresses reveal near the crack tip. This conclusion agrees with the past reference. Furthermore, the compressive condition can retard and stop the crack growth during the Joule heating process. Keywords—Compressive stres...
