Unsteady flow of Williamson fluid under the impact of prescribed surface temperature (PST) and prescribed heat flux (PHF) heating conditions over a stretching surface in a porous enclosure

An unsteady mixed convection flow of Williamson nanofluid over a stretchable surface embedded in porous medium is scrutinized numerically. Here the characterized by Darcy Forchheimer model under influence magnetic field. Heat transfer analysis with two different conditions namely, prescribed temperature (PST) and heat flux (PHF) are taken into account. The evolved mathematical numerically solved utilizing Keller box method bvp4c solver MATLAB. significance diverse non-dimensional physical parameters on considered problem thoroughly demonstrated discussed for velocity, concentration profiles through graphs tables. From outcomes, it stipulated that velocity fluid enhances buoyancy ratio parameter whereas switch pattern spotted distributions both including conditions.
