Peristaltic flow of rotating couple stress fluid in a non-uniform channel

Peristaltic flow of rotating couple stress fluid in a non-uniform channel

An analysis has been carried out for thermal radiation effects on peristaltic activity of couple stress fluid in a non-uniform rotating channel. The velocity and thermal slip effects at the channel boundaries are considered. Heat transfer with non-uniform heat generation/absorption effect is also ta...
