Abstract

In this paper, we examined the combined effects of  dissipation and  chemical reaction in Casson nanofluid  motion  through  a  vertical  porous  plate  subjected  to  the  magnetic  field  effect  placed perpendicular  to  the  flow  channel.  The  physical  problem  is  modeled  using  partial  differential 
equations (PDEs). These sets  of PDEs,  with suitable similarity transformations,  are simplified into ordinary differential  equations (ODEs). Collocation technique with legendary basis function  isutilized in solving the transformed equations. The numerical analysis on velocity, concentration,and temperature are plotted and tabled for different flow parameters. Our findings show that  by raising  the  Casson  parameter  close  to  infinity,  the  behavior  of  Casson  fluid  obeys  the  law  of viscosity.  Conversion  of  energy  via  the  work  done  by  the  fluid  molecules,  influences  both dimensionless  velocity  and  temperature  profiles  significantly,  while  the  mass  flux  hikes  the concentration profile. The heat generated by the intermolecular reaction of fluid particles resulted in a large amount of heat produced in the flow field.
