The influence of heat and mass transfer has been carried out in the peristaltic transport of Johnson Segalman fluid in a curved channel with flexible walls. The relevant flow problem is modeled. The solution analysis is given under long wavelength and low Reynolds number approximations. Expressions for stream function, temperature and concentration fields are derived. The effects of emerging parameters in the obtained solutions are plotted and analyzed. (C) 2012 Elsevier Ltd. All rights reserved.
