Hall and radial magnetic field effects on radiative peristaltic flow of Carreau–Yasuda fluid in a channel with convective heat and mass transfer

• Hall current in Carreau–Yasuda fluid is examined.
• Soret and Dufour effects are retained.
• Thermal radiation contribution is addressed.
• Convective conditions for both heat and mass transfer are considered.

The purpose of present investigation is to study the Hall and MHD effects on peristaltic flow of Carreau–Yasuda fluid in a convectively curved configuration. Thermal radiation, Soret and Dufour effects are also accounted. The channel walls comprised the no slip and compliant properties. Constitutive equations for mass, momentum, energy and concentration are first modeled in view of considered assumptions and then simplified under long wavelength and low Reynolds number approximation. Solution of the resulting system of equations is carried out via a regular perturbation technique. Physical behaviors of velocity, temperature, concentration and streamlines are discussed with the help of graphical representation.
