Abstract: This paper scrutinises the influences of aligned magnetic field and nonlinearly radiative flow of Falkner-Skan Casson liquid towards a wedge which is filled with microorganisms and nanoparticles. Following Buongiorno's model, the expressions of flow are developed and then transformed into self-similar form by utilising appropriate similarity transformations. Numerical outcomes are presented through plots and tabular form by enforcing Newton's and Runge-Kutta techniques. The impacts of arising constraints on liquid velocity, temperature, density of motile organisms and concentration are explored. For industrial and engineering interest, surface drag coefficient, rates of mass and heat transport, motile microorganism's density number are investigated. A comparative analysis for two cases namely aligned magnetic field (AMF) and magnetic field (MF) demonstrates that rate of heat and mass transfer are high in AMF case in comparison to MF case, and therefore desired results can be obtained by utilising AMF case.

Keywords: Casson fluid; Falkner-Skan flow; nanoparticles.
