Peristaltic Flow in a nonUniform Channel with Heat and Mass Transfer

The combined effect of heat and mass transfer on the peristaltic flow of fourth-grade fluid in a non-uniform channel has been investigated. Flow analysis has been carried out in the presence of an induced magnetic field. The governing flow equations have been transformed in a wave frame. The arising equations have been solved for the stream function, pressure gradient, temperature, concentration, magnetic force function, induced a magnetic field and current density. The role of embedded parameters is displayed and discussed.
