The present investigation establishes with analytical relevance for the thermal analysis in biological transport of Eyring–Powell fluid through a noncircular horizontal 3D channel. The relevant equations are physically exhibiting the problem under the lubrication mechanism. The wave frame analysis for the current study is considered to have a steady format of the problem. The resulting equations are presented with their analytic treatment by couple of series and closed-form techniques jointly. The aspects of different flow parameters are presented through plotting two- and three-dimensional curves of velocity expression, pressure gradient profile, peristaltic pressure data, temperature curves and mass distribution. The circulating bolus variation is also disclosed for the physical parameters to observe the stream lines pattern. It is observed from obtained graphical aspects that transfer of heat and mass is reduced for Eyring–Powell fluid model than a Newtonian fluid, but the same is enhanced with the aspect ratio of the three-dimensional rectangular channel.
