Fluid Dynamics and Turbulent Flows

The present article makes on the presence of the magnetohydrodynamic (MHD) flow of an electrically conducting Newtonian fluid over a superlinear stretching/shrinking sheet. A similarity transformation is utilized to interpret the representing construction of nonlinear PDEs by nonlinear ODEs. These equations are solved analytically along with the corresponding boundary conditions. The impact of radiation, mass transpiration, and carbon nanotube (CNT) volume fraction on MHD Newtonian fluid flow and heat transfer is under investigation. Water, ethylene glycol, and engine oil are used as base liquids in the sample along with single and multi-walled carbon nanotubes (MCNTs). Heat transfer in an electrically conducting fluid, including internal heat generation and absorption, is evaluated over a continuously stretching/shrinking sheet with power-law surface temperature or heat flux. Furthermore, the heat equation is solved analytically via the Kummer's function and WKB method, respectively. The studied results verify that CNTs have significant properties in improving heat transfer processes which have been extensively developed in manufacturing industrial applications, especially in nanomedicine, where the use of carbon nanotubes as drug-carriers is being pursued, particularly in cancer treatment.
