We develop a simple mathematical model for forced flow of culture medium through a porous scaffold in a tissue-engineering bioreactor. Porous-walled hollow fibres penetrate the scaffold and act as additional sources of culture medium. The model, based on Darcy's law, is used to examine the nutrient and shear-stress distributions throughout the scaffold. We consider several configurations of fib...

Bacterial growth and its interaction with water flow was investigated in a two-dimensional flow field in a saturated porous medium. A flow cell (56 x 44 x 1 cm) was filled with glass beads and operated under a continuous flow of a mineral medium containing nitrate as electron acceptor. A glucose solution was injected through an injection port, simulating a point source contamination. Visible li...

The aim of current Paper is to examine the effect/result ‘heat source’ parameter over a wedge through porous-medium for electrically-conducting fluid flow magneto hydrodynamic Casson nanofluid with activation energy. influence/impact ‘second law’ analysis electrically conducting fluid(s) chemical-reaction also investigated. Dimension-less ordinary differential equations(ODE) are obtained/derive...
