“…Electric field with less than 500 V/m strength is used in medicine for inserting drugs into tumors, healing wounds, tissue engineering and stimulating neurons [21]. Mirza et al [22] and Ponalagusamy and Manchi [23]) examined the blood flow under the action of electric field and found that the increase of electric field strength decreases the flow impedance and rises the flow speed under diseased conditions.…”

A theoretical model is proposed to investigate the coupled effects of thermal radiation and electromagnetic field on the blood flow in a stenosed tapered artery. Here, blood is treated as a non-Newtonian Jeffrey fluid model which includes magnetic particles. The magnetohydrodynamic flow is pulsatile, and exhibits slip velocity at the complaint wall. The flow medium consists of a cylindrical rigid tube with porous medium that is subjected to periodic body acceleration, transverse external magnetic field and applied electric field in the axial direction. Assuming the existence of mild stenosis, a set of flow governing equations is solved using integral transform method. Further, exact solutions are computed for non-dimensional temperature and velocity profiles of fluid and particles. Additionally, equations for different flow characteristics such as wall shear stress, volumetric flow rate, and flow resistance are derived and discussed through graphical illustrations. Results demonstrate that the temperature of blood increases with the increase of heat absorption coefficient and time. However, the temperature decreases with the increase of radiation number and Peclet number. While the velocity profile is directly proportional to the Grashof number and heat absorption coefficient, it is inversely proportional to the radiation number and Peclet number. The applied electric field diminishes the magnitude of fluid's flow resistance, but it increases with the increase of the magnetic field strength. By combining heat radiation with electromagnetic field, this study contributes to new insights to the physical properties of blood.

“…Further, Ponalagusamy and Priyadharshini [18] discussed the effect of magnetic field on two-phase blood flow through a tapered stenosed artery, assuming micropolar fluid in the core region and Newtonian fluid in the plasma region. A mathematical model presented by Mirza et al [19] analyzed the effect of magnetic field on a transient laminar electromagneto-hydrodynamic two-phase blood flow using a continuum approach. Solving the model analytically they displayed the effect of the magnetic field for both blood velocity and particles velocity separately and concluded that as the effects of the magnetic field increases, both blood and particles velocities decrease for electromagnetohydrodynamic two-phase blood flow.…”

In this paper, effects of heat and mass transfer on two-phase pulsatile blood flow through a narrowed stenosed artery with radiation and the chemical reaction has been investigated. A vertical artery is assumed in which magnetic field is applied along the radial direction of the artery. The characteristics of blood in narrow arteries are analyzed by considering blood as Newtonian fluid in both core as well as in plasma regions. Exact solutions have been found for velocity, energy and concentration equations of the blood flow. To understand the behavior of blood flow, graphs of velocity profile, wall shear stress, flow rate, flow impedance and concentration profile have been portrayed for different values of the magnetic and radiation parameter. In order to validate our result, a comparative study has been presented between the single-phase and two-phase model of the blood flow and it is observed that the two-phase model fits more accurately with the experimental data than the single phase model. For pulsatile flow, the phase difference between the pressure gradient and flow rate has been displayed with magnetic field parameter and height of the stenosis. Contour plots have been plotted for 10%, 20% and 30% case of an arterial blockage.

“…Secondly, the hydraulic torque converter is generally required for the operating environment, so its applicability in the harsh natural environment of the wind farm remains to be verified [17]. Thirdly, variable speed constant frequency operating range of wind turbine with hydraulic torque converter is restricted [18]. Fourthly, the manufacturing cost of the torque converter is high, which leads to the failure of mass production.…”

Large-scale wind turbines have become the trend of the wind power industry. However, the main factors restricting the large scale wind turbines are frequent replacement of carbon brush and slip ring and the harmonic of the stator current in double-fed induction generator, plus converters' large volume, high cost, and high failure rate in full power converter of wind turbine. Therefore, new double rotor speed-regulating wind power generation system comprising a double rotor speed-regulating device connected to the gearbox and the synchronous generator is proposed for the sake of lower cost, higher reliability, and stronger adaptability of the power grid. The structure of the system and the connection of each component are described; meanwhile, the working principle of the system under different operating conditions is analyzed. Furthermore, the mathematical model of the system is established, besides the control strategy being proposed. The simulation results verify the correctness of the mathematical model and the control strategy.
