Oberbeck convection flow of a couple stress fluid through a vertical porous stratum

摘要: Abstract The flow and heat transfer characteristics of Oberbeck convection a couple stress fluid in vertical porous stratum is investigated. perturbation method solution obtained terms buoyancy parameter N valid for small values . This limitation relaxed through numerical solutions using the finite difference technique with an error 0.1×10 -7 effect increase temperature between plates, permeability on velocity, temperature, mass rate, skin friction rate are reported. A new achievement explored to analyse strong, weak comparable porosity parameter. It noted that both suppress flow. Higher-temperature required achieve equivalent viscous
