AbstractThere is an intense worldwide activity in the development of instrumentation for medical diagnosis and bioscreening based on biological labeling and detection of nanoparticles. Based on this profound observation, Hall and ion slip effects on magnetohydrodynamic (MHD) free convective rotating flow of nanofluids in a porous medium past a moving vertical semi-infinite flat plate are investigated. The equations for governing flow are solved analytically by perturbation approximation. The effects of various parameters on the flow are discussed through graphs and tables. The velocity increases with Hall and ion slip parameters. An increase in the convective parameter led to amplify the thermal boundary layer thickness, but when the heat generation parameter is taken into consideration, an opposite effect occurs. The skin friction coefficient increases with an increase in nanoparticle volume fraction and it reduces with increase in Hall and ion slip parameters. Outcomes disclose that the impact of thermal convection of nanoparticles has increased the temperature distribution, which helps in destroying the cancer cells during the drug delivery process.

Abstract A steady incompressible chemically reacting fluid between two disks under the influence of cross-diffusion, Hall and ion-slip effects is studied by assuming the lower disk is rotating and the upper disk is stationary. The system of nonlinear differential equations representing velocity, temperature and concentration is solved numerically using spectral quasi-linearisation method. The effects of chemical reaction, Hall current and ion-slip, Dufour and Soret on velocity, temperature and concentration distributions are studied. The stress, rate of heat and mass transfers are discussed for various parameters and the results are displayed in the tabular form. It is found that increasing Hall parameter decreases the temperature and concentration, and the opposite trend observed when ion-slip parameter increased. The concentration reduces with the enhance of the chemical reaction parameter and Soret number.
