A three dimensional frictional flow study of Williamson fluid with chemical reaction.

• An incompressible three dimensional viscously dissipated Williamson fluid is analyzed. • Fluid flow is generated by an irregular non-linear stretching surface. • Effects of heat generation and chemical reaction are examined. • Local skin friction, Nusselt number and mass transfer rate are also calculated. This analysis deals with the incompressible, steady, three-dimensional (3D) viscously dissipated Williamson fluid flow near an irregular surface. It has many applications such as synthesis of polymer solutions, plastic manufacturing, food processing, paper production, adhesives, exotic lubricants, suspension solutions etc. The phenomenon is examined in semi-infinite domain and the flow is produced by means of non-linear stretching. An irreversible process is taken by means of fluid particles stress which converts the energy into heat. The most noticeable procedure of this process is the internal friction between the layers of fluid particles which causes heat generation. The governing equations are initially reformed into ODES by applying applicable variables and then numerical solutions are computed via the shooting technique. Newly characteristics of dimensionless variables are illustrated by means of graphs and tables. The detail analysis anticipates that velocity declines by the elevation of Weissenberg number and wall thickness parameters. Further, the temperature enhances with the increase of Eckert number and heat generation parameter and behaved oppositely analogous to development in Prandtl number. [ABSTRACT FROM AUTHOR]
