“…Numerous model studies on the effect of Hall currents in the magnetohydrodynamic (MHD) problems of one fluid flow system can be found in literature [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. A great number of studies are also available on MHD two-phase/two-fluid flow problems due to their abundant applications in various domains [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]. In most of these studies, the flows are assumed under the steady-state conditions.…”

An unsteady magnetohydrodynamic (MHD) heat transfer two-fluid flow of ionized gases through a horizontal channel between parallel non-conducting plates, by taking Hall currents into account is studied. The governing partial differential equations that describe the flow and heat transfer under the adopted conditions are solved for the velocity and temperature distributions by a regular perturbation technique. Profiles for the velocity and temperature distributions as well the rates of heat transfer coefficient are presented graphically, and a parametric study is performed. The results reveal that the combined effects of the Hartmann number, Hall parameter, and the ratios of viscosities, heights, electrical and thermal conductivities have a significant impact on an unsteady MHD heat transfer two-ionized fluid flow characteristics.

“…However, it is seen that negative directionally applied electrical field with magnetic field behaves reverse effect and so reduces the heat flux from the flow body. In [4,6,12,18] is clearly seen that increase of positive directional electrical and magnetic field increases surface heat flux but also Negative directional electrical field weaken the impact of magnetic field. The variation of volume average rate Nusselt number was evaluated by the application of electrical field intensity values are as ±1e-4 V/m, 0 V/m, ±1e-5 V/m during the application of magnetic field induction (B = 0 T, B = 0.05 T, and B = 1 T) and was presented in fig.…”

“…It is concluded that by applied magnetic field, velocity in the channel is reduced and the maximum amount of temperature increases. Selimli et al [4] studied computationally combined effect of externally applied magnetics and electrical field on the magneto-viscous fluid-flow. It is concluded that increase of positive directional electrical and magnetic field decreases the flow velocity.…”

Cooling period of liquid metal while flowing under imposed magnetic and electrical field was studied for laminar steady flow condition. Computational analyses were done by ANSYS Fluent software MHD module. For applied each constant value of magnetic field induction (B = 0 T, B = 0.05 T, B = 1 T), the electrical field intensity was applied positively as E + (1e-4, 1e-5) V/m and negatively as E − (-1e-4,-1e-5) V/m. Increase of the E+ field intensity decreased the local temperature (increased cooling rate) but also increased the heat flux and Nusselt number. Also, decrease of E − in the opposite direction increased the temperature but also decreased the heat flux and Nusselt number. It could be signified that by the application of magnetic field or together with electrical field, the heat transfer could be improved or attenuated.

“…In addition, with the increase of the positive electric field, the flux field of the magnetic field has increased the thermophysical and hydrodynamic properties of the fluid. However, it has been observed that the electric field applied by increasing in the negative direction reduces the effect of the magnetic field [15].…”

The importance of using solar energy, one of the renewable energy sources, has started to be understood more recently. The negative environmental effects and limited amounts of fossil fuels have led to increased demand for renewable energy sources worldwide and the production of various models and devices has accelerated to take advantage of solar energy, which is the basis of all energy sources. Using solar collectors as a way to benefit from solar energy has been used for many years. Although solar collectors are generally divided into 4 types as flat plate (FPSC), evacuated tube (ETSC), parabolic (PSC) and heat pipe (HPSC), these types can also be divided into separate types with many different features. The most commonly used solar collector type in the world is Flat Plate Solar Collector. The most important reasons for this are being cheap, easily produced and applied in various ways. Yet, the thermal productivity of FPSCs decreases below 40% in non-ideal climate conditions with low surrounding temperature. The existence of such disadvantages of FPSCs led to the production of Evacuated Tube Solar Collectors. With the advancing technology, the utilization of heat pipes in collectors has come to the agenda and as a result of the studies conducted, it has been determined that the use of heat pipe improves efficiency. In addition, the use of nanofluids in solar collectors and heat pipes has become quite common, and many studies have been carried out especially on this subject recently. The primary objective is always to improve the performance of the system and achieve efficiency. In this way, solar energy will be used in the most effective way and world energy supply demand will be met by using renewable resources.
