What is A generalized perspective of Fourier and Fick’s laws: Magnetized effects of Cattaneo-Christov models on transient nanofluid flow between two parallel plates with Brownian motion and thermophoresis about?

Present research article reports the magnetized impacts of Cattaneo-Christov double di usion models on heat and mass transfer behaviour of viscous incompressible, time-dependent, two-dimensional Casson nano uid ow through the channel with Joule heating and viscous dissipation e ects numerically. The classical transport models such as Fourier and Fick's laws of heat and mass di usions are generalized in terms of Cattaneo-Christov double di usion models by accounting the thermal and concentration relaxation times. The present physical problem is examined in the presence of Lorentz forces to investigate the e ects of magnetic eld on double di usion process along with Joule heating. The non-Newtonian Casson nano uid ow between two parallel plates gives the system of time-dependent, highly nonlinear, coupled partial di erential equations and is solved by utilizing RK-SM and bvp4c schemes. Present results show that, the temperature and concentration distributions are fewer in case of Cattaneo-Christov heat and mass ux models when compared to the Fourier's and Fick's laws of heat and mass di usions. The concentration eld is a diminishing function of thermophoresis parameter and it is an i
