Summary
Nanoliquids are another class of
heat transfer in which Liquid containing nanoparticles of size under 100 nm
which are uniformly and stably suspended. Energy transportation of the
nanoliquid is influenced by the properties and measurement of nanoparticles and
in addition the solid volume fraction. Compared with base liquids, various
recent investigations have shown sensational enhancements in effective static
thermal conductivity. In numerical examinations two strategies are utilized for
simulation of nanoliquid hydrothermal behavior:
1. Single-phase model
2. Two-phase model.
The convection and heat transfer
enhancement technique using an electric field or electrostatic power produced
from polarization of the dielectric liquid can be one of the most promising
methods among different dynamic procedures due to its several advantages, for
example, simplified implementation using only a transformer and electrodes and
small consumption of electric power. This procedure is oftenly called the
electrohydrodynamic (EHD) strategy for heat transfer, which refers to the
interdisciplinary field and deals with subjects concerning the interactions
between electric field, flow field, and temperature field.
Study of magnetic field phenomenon
has attracted many attentions in engineering sciences because of its wide
applications, for example, in the polymer industry and metallurgy where
hydromagnetic techniques are being utilized. To be more particular, it may be
pointed out that most of the metal surgical processes include the cooling of
continuous strips or laments by drawing them through a quiescent liquid and
during this process these strips are sometimes stretched. Magnetic field
sometimes considers as a variable according to time or space variable. A
Ferro-liquid acts as a fluid which is influenced by an external magnetic field
and externally applied magnetic fields. It can be used to control and direct
the flow of Ferro-liquids, which is applicable in various fields like
mechanical engineering, electronic packing, thermal engineering, and aerospace.
In different applications, for example, in free convective heat transfer, the
heat transfer rate can be reducing by applying the magnetic field. But in many
other applications like cooling of electric device, the goal is to increase the
heat transfer rate. Henceforth, using nanoliquid in such application can be
useful. Ferro-liquids is a magnetic nanoliquid which can be influenced by
magnetic and electric field.
Considering the aforementioned
significance of nanofluids, the Fluid Dynamics & Materials Processing

“Electro- magnetohydrodynamic nanoliquid flow and heat transfer” within its
