Title Swirling Flow of Maxwell Fluid with Bioconvection Phenomenon

Author(s) Maryam Ehsan Abbasi

Abstract Dynamics of non-linear fluid viscoelastic fluid with bioconvective properties is the core concern of the present thesis. There are many applications for non-linear fluids can be found in industry. Such as production of polymer and plastic sheets etc. encounter these types of the fluid flow. Therefore, in this era the scientists put their efforts to investigates the flow and thermal transport features of non-Newtonian fluids. These types of the liquids include time-dependent, timeindependent and viscoelastic type fluids. The viscoelastic type of fluid exhibits both viscous and elastics effects. The deformations tensor for viscoelastic non-linear fluids is used in empirical model called “Maxwell fluid model”. This model is the part of the present study in swirling type flow phenomena which is induced by rotating cylinder. Both Dufour and Soret effects are also included in the energy equation for the thermal analysis. The governing equations are changed into a set of nonlinear ordinary differential equations with appropriate flow ansatz. In MATLAB bvp4c, the converted nonlinear ordinary differential boundary value problem is solved with suitable boundary conditions. The impacts of dimensionless factors on velocity, temperature, concentration, and concentration of microorganisms are visually depicted in graphical abstract using a comparison of constant wall temperature (CWT) and prescribed surface temperature (PST).
