Thermal analysis of MHD casson-sutterby fluid flow over exponential stretching curved sheet

Abstract

The two-dimensional flow of Sutterby-Casson fluid flow over an exponentially curved sheet is considered. Incompressible and steady flow is taken into account. The magnetic and electric fields are ignored due to the small Reynolds number in the flow assumptions. Magnetic and chemical dipoles are considered at stretchable curved sheet. Heat generation and slip phenomena have been considered in the present analysis. The governing models of the above assumptions are reduced by implementing the boundary layer approximations and gained nonlinear coupled differential equations. The couple differential equation system is reduced in a dimensionless system (ordinary differential equations) using appropriate transformations. The dimensionless system is solved through a numerical scheme due to finding the results involving physical factors. The results are highlighted in graphs and as well as tables. Concentration achieved higher values by enlargement in the Brownian factor. The movement of particles becomes faster due to the enlargement of the Brownian factor, ultimately increment in concentration. Energy activation factor values enlarged which gained lesser values of Nusselt factor and mass transfer factor while friction factor remains constant. The reaction of chemical factor impact on mass transfer, friction factor, and heat transfer have been debated.
