摘要: In the case of steady flow a fluid under combined influence external electric and magnetic fields, moves forward by forming an axial momentum boundary layer. With this end in view study has been performed here to investigate problem entropy generation during electroosmotically modulated third-order electrically conducting flowing on microchannel bounded silicon-made parallel plates field, paying due consideration steric effect. The associated mechanism heat transfer also duly taken care of, considering Cattaneo-Christov flux. A suitable finite difference scheme developed for numerical procedure. detailed velocity temperature distributions made their variations with respect different physical parameters involved problem. results computation have displayed graphically. computational work carried out blood as working fluid, motivation exploring some interesting phenomena context hemodynamical micro-vessels. Among other variables, parametric important viz. i) skin friction ii) Nusselt number investigated. confirms that random motion particles can be controlled adjustment intensity externally applied field transverse direction. It is further revealed diminishes, Prandtl gradually increases; however, increase occurs thermal relaxation. Entropy found enhanced Joule heating. present validated proper manner.
