CONVECTION DRIVEN FLOW BETWEEN MOVING DISKS- A NON-LINEAR APPROACH FOR MODELLING THERMAL RADIATION

Flows involving two disks have significant applications in heat exchangers, rotating machinery parts, data storage devices, oceanography and viscometers. In this investigation, mass transfer characteristics are examined Casson flow between orthogonally moving disks, with nonlinear thermal radiation under the slip convective conditions, using powerful tool of similarity transformation. A MATLAB code, based on quasi-linearization, has been developed for numerical study. It is observed that, when receding, disk expansion ratio raises velocity profile near center region disks. The trend is, however, reversed approaching each other. Moreover, all governing parameters remarkably elevate fluid temperature at a central both cases. remarkable lowering concentration distribution also noted Schmidt number chemical reaction parameter. Finally, compared to profiles, it which least affected.
