Abstract

Abstract

Combined heat and mass transfer on free,forced and mixed convection flow along a porous wedge with magnetic effect in the presence of chemical reaction was investigated.The flow field characteristics were analyzed using the Runge-Kutta Gillwith shooting method as well as the local non-similarity method up to thirdlevel of truncation was used toreduce the governing partial differential equations into nineord inary differential equations.The governing boundary layer equations were written into a dimensionless form by Falkner-Skan transform ations.Because of the effect of suction/injection on the wall of the wedge with buoyancy force and variable wall temperature,the flow field is locally nonsimilar.Numerical calculations up to thirdorder level of truncation are carried out for different values of dmiension less param eters as a special case.Effects of the strength of magnetic field in the presence of chemical reaction with variable wall temperature and concentration on the dimensionless velocity,temperature and concen tration profiles are shown graphically.
- local non-similarity,
- suction/injection,
- buoyancy force,
- magnetic field and suction at the wall of the wedge,
