Flow of a Eyring–Powell fluid in a scraped surface heat exchangers (SSHEs) is analyzed. Foodstuff behaves as non-Newtonian material so for studying non-Newtonian effects inside SSHE Eyring–Powell fluid model is considered. As every physical phenomena can be interpreted mathematically therefore in this work we mathematically studied flow inside SSHE. Steady isothermal incompressible flow of Eyring–Powell fluid about a periodic sequence of pivoted scraper blade in channel with one moving wall and other is stationary, pressure gradient is imposed in the direction transverse to the wall motion is modelled using lubrication approximation theory as the gap with the blades and device wall are narrow. The resulting nonlinear boundary value problem is solved using Adomian decomposition method. Expression for velocity profiles for different region, flow rates, stream function, forces on the wall and on the blade are found. Graphical representation for velocity profile and for different flow parameter involved is also discussed. Parabolic velocity profiles in various region of SSHE are obtained which are in line with the experimental results obtained through MRI.
