..., the concentration field and the trapping phenomena have been discussed. The results reveal that the temperature distribution is parabolic in shape, and it decreases with increasing slip parameter and Weissenberg number while it increases as the Prandtl number and the Eckert number increase. Originality/value...

... solution is obtained for the case in which Weissenberg number is small. The effects of Hartmann number, Weissenberg number, power‐law index and amplitude ratio on the pressure rise and the friction force are discussed. The trapping limit and the trapping occurrence region at the centerline decrease...
