non-linear beam, in many mathematics and engineering applications are significant heat Still enhanced to improve heat [12, 13] A mixture of pure liquids and extremely small nanoparticles is called nanofluids. Nanofluids provide a good heat conduction rate Regular fluids.[14, 15] Flow and heat transfer from the flow of nanofluids across a rotating disc with sliding velocity and magnetic field [16] The phenomenon of conduction and Heat transfer through the study of flow analysis caused by microorganisms and Nanoparticles pass through flexible surfaces with irregular magnetic fields [17] investigated the thermal conductivity and the effect of viscosity on the magnetic rheology induced by Nanofluid from flexible vertical tube. It can be controlled using a pressure gradient via the obviosity parameter. Nanofluids can be produced by dispersing two distinct systems of nanoparticles in Medium of normal liquids. Challenges and applications On nanofluids in Studies [18, 19]. Challenges and applications of nano fluidics in studies [20, 21]. The effect on the flow of electrical forces aided through vessels induced by second-order nanofluids was studied [22, 23]. Flow and heat transfer characteristics were performed [24, 25]. Flow processes for transporting liquids and nanoparticles at high temperature, focusing on flexible ribbons, liquefaction efficiency, supersonic extrusion, etc., are all examples of engineering and technological procedures that need to be studied in extended flow[26, 27]. An examination the implementation of stability can determine the degree to which it can tolerate unsteady flow parameters[28]. It turns out that there are two solutions in a larger space with a higher parameter value. Investigation of nanofluid flow.
dual-flow solutions of a nanofluid above a disk moving under the influence of oscillating currents. Standard equations are in two dimensions using appropriate transformations. Choosing appropriate transformations, the partial differential equations (PDEs) representing the heat transfer problem are transformed into ordinary differential equations (ODEs). The basic equations have been solved Using "bvp4c function numerically in MATLAB". The present results are validated with available comparison and a very close accuracy was obtained. A comparison was presented between the solutions we arrived at with the numerical solutions, and this indicates Excellent convergence. To solve in the upper part for all values of nanofluid circular parameter , and attraction Parameter . However, a change in the bottom solution is observed at some moderate values and in addition, the radial velocity increases due to the nanofluid while the velocity decreases at others. However, the temperature rises due to nanofluids. The results also indicate Until the circular parameter increases its speed in both directions and the temperature decreases. It increases and then decreases with respect to the tangential component of the velocity, but the temperature increases monotonically. Key Words: Unrestricted, Flow axisymmetric flow fluid kinematics, partial differential equations, engineering quantities.
1.INTRODUCTION The flow caused by the circular disc has a lot to do with it engineering and industrial applications for example in wastewater treatment, computer storage treatment devices, aerospace technology, stator system, solar thermal manufacturing and geothermal mineral extraction process, The Newtonian fluid was above a steadily rotating disk [1, 2]. Due to the huge impact Magnetic field on flux [3] examined Flow through the circular disc port. Instead, [4] Study multiple solutions for a pure liquid to flow over a rotating disc subject to time Impairing the free, unrestricted flow. you will be the importance of rotating discs in moving turbines [5, 6] by studying the magnetic flux on a rotating disc.[7, 8] The effect of force, ionic slip, and ohmic heating on a steady flow over a rotating disk.[9] developed ideal solutions for magnets and constant and viscous fluid flow the study was carried out taking into account temperature and mass transfer along with thermophysical properties and their variation [10, 11].
