Local nonsimilarity solution for the impact of the buoyancy force on heat and mass transfer in a flow over a porous wedge with a heat source in the presence of suction/injection

Abstract

Combined heat and mass transfer in free, forced and mixed convection flows along a porous wedge with internal heat generation in the presence of uniform suction or injection is investigated. The boundary-layer analysis is formulated in terms of the combined thermal and solute buoyancy effect. The flow field characteristics are analyzed using the RuugeKutta-Gill method, the shooting method, and the local nonsimilarity method. Due to the effect of the buoyancy force, power law of temperature and concentration, and suction/injection on the wall of the wedge, the flow field is locally nonsimilar. Numerical calculations up to third-order level of truncation are carried out for different values of dimensionless parameters as a special case. The effects of the buoyancy force, suction, heat generation, and variable wall temperature and concentration on the dimensionless velocity, temperature, and concentration profiles are studied. The results obtained are found to be in good agreement with previously published works.

Local non-similar solutions of convective flow of Carreau fluid in the presence of MHD and radiative heat transfer

“…Muhaimin and Kandasamy [2] exhibited an examination tends to the magnetic effects and chemical reaction over a wedge with porosity. After that Muhaimin et al [3] found the local non-similar solution for the chemical reactions with Mhd, mixed convection and suction/injection. Furthermore non-Newtonian fluids are discussed with different effects presented through [4][5][6][7].…”
