Abstract
•Peristaltic flow of MHD tangent hyperbolic fluid is modelled.•Impact of variable viscosity is examined.•Channel walls are inclined and symmetric.•Joule heating and viscous dissipation are examined.•Solutions are executed numerically.
This investigation examines the influence of variable viscosity on peristaltic transport of tangent hyperbolic fluid with heat and mass transfer. Viscous dissipation and Joule heating have been taken. Temperature dependent viscosity is considered. An electrically conducting fluid is taken in symmetric inclined channel. Effect of heat and mass transfer are outlined. Channel inclination dominates gravitational effects such that the mixed convection is not ignored. Soret and Dufour effects are highlighted. The mathematical expressions are subject to lubrication approach. Decline in velocity is noticed with an increase in magnetic field and gravitational effects. Whereas larger values of Soret and Dufour number raise the temperature and heat transfer rate. The graphs in present communication have been sketched directly using NDSolve built in routine of Mathematica.
