Abstract
This paper presents an analysis on steady magnetohydrodynamic boundary layer flow of Casson nanofluid with microorganisms near an expandable boundary in a porous medium. The flow behaviour is analysed by incorporating impacts of magnetic field applied in a direction which makes an angle α∗ with the boundary and convective conditions in temperature, nanoparticle concentration and microorganism density at boundary. Non-dimensionalised nonlinear and coupled system of ordinary differential equations are solved by exercising a numerical algorithm termed as spectral local-linearization method. The considered numerical algorithm is found to be convergent and capable of yielding accurate results. Graphical sketches of solutions obtained are produced and explained the variations in characteristics of flow, heat transfer, nanoparticle and microorganism density. The considered model may help to understand the application of solar energy in processes of thermal engineering. This study has direct relevance to cooling of metallic plates, industries of glass and polymer, heat exchanger, improving oil recovery through microbes, creating biofilms with the help of microorganisms and developing bio-nano cooling systems, etc. This study reveals that temperature profiles are highly influenced by Biot and Eckert numbers.
