      abstract = {The objective of this paper is to investigate the combined effects of Diffuson ? Thermo ( Dufour), thermal radiation, absorption of radiation and chemical reaction on MHD oscillatory flow of an optically conducting thin fluid in an asymmetric wavy channel filled with porous medium. Analytical expressions for the velocity, temperature and concentration profiles are obtained. Solutions are analyzed graphically for different values of arising parameters such as Schmidt number (Sc), Peclet number (Pe), Reynolds number (Re), absorption of radiation parameter (Ra), Dufour parameter (DT ), thermal Grashof number (Gr), solutal Grashof number (Gm), porous medium shape factor  parameter (S), radiation parameter (N), magnetic parameter (M), chemical reaction parameter (K1), the geometric parameter?s like amplitude ratio?s (a and b), mean half width of the channel (d) and Phase angle (?t).  The expressions for skin friction and the rate of heat and mass transfer coefficients at the channel walls are derived and discussed numerically for different physical parameters and exhibited in tabular form. The velocity and temperature   increase with increasing radiation parameter and Dufour number whereas the concentration decreases with increasing chemical reaction parameter and Schmidt number. This study is carried out to obtain a better understanding of the flow instabilities with heat and mass transfer in wavy passages so that design guidelines may be developed.},
