摘要

Highlights?Peristaltic flow of Sutterby fluid in curved geometry is analyzed.?Thermal radiation and viscous dissipation effects are used to model the energy equation.?Lubrication approach is adopted to simplify the problem.?Pumping and trapping phenomenon is discussed.AbstractA study is carried out to examine the peristaltic flow of Sutterby fluid in curved channel. The magnetic field is applied in radial direction. Magnetic Reynolds number is taken small. Viscous dissipation and thermal radiation effects are used to model energy equation. Lubrication approach is applied for the problem simplification. Solutions for stream function (ψ), velocity (u) and temperature (θ) for fluid parameterβhave been derived. The results of velocity are analyzed graphically. The impacts of physical parameters on pumping and trapping are also explained in detail. The study discusses that velocity becomes symmetric about the central line for larger values of curvature parameterk.]]>
