【 摘 要 】

This paper is concerned to investigate the radiation effect on hydromagnetic flow along a vertical impermeable wavy texture. The wavy texture is considered to be heated with uniform flux. The flow behavior over the geometry is modeled through the partial differential equations and then non-similar solution is obtained by an highly efficient well known Keller-box method. To show the accuracy and validity of the code and developed results, a comparison is made with those available in the literature for the limiting case Rd=0 and M=0. It has been noticed that the produced results are in good concordance with the previously reported results. The outcomes of the associated parameters such as radiation–conduction parameter, amplitude of the waviness, Prandtl number and magnetic parameter with flow and heat transfer rates are explained through various graphs. It is noticed that the flow and heat transfer rates can be controlled through the variation of radiation–conduction parameter. Most importantly, the increase in the amplitude of waviness lessens the flow of fluid and heat transfer rate in the boundary layer.
