【 摘 要 】

This article reflects the features of convective heat transfer with radially magnetic field of an incompressible Williamson fluid with peristaltic motion and Joule heating in a curved channel. Mathematical study has been carried out with low Reynolds number under consideration of long wavelength approximations. The system of nonlinear equations with small values of Weissenberg number has been obtained and solution of these equations has been constructed. The spectacular characteristics of flow quantities are carried out with special focus on velocity, temperature, heat transfer and trapping. It is examined that pressure gradient heightens for large values of Weissenberg number and magnetic field parameter. The velocity and temperature shows low behaviour for magnetic field parameter and moreover Weissenberg and Biot numbers has opposite effect on temperature distribution. Streamlines pattern are also represented with different parameters.
