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.
