Towards the minimization of thermodynamic irreversibility in an electrically actuated microflow of a viscoelastic fluid under electrical double layer phenomenon

摘要: We discuss the entropy generation minimization for electro-osmotic flow of a viscoelastic fluid through parallel plate microchannel under combined influences interfacial slip and conjugate transport heat. use in this study simplified Phan-Thien–Tanner model to describe rheological behavior fluid. Using Navier’s law thermal boundary conditions third kind, we solve equations analytically evaluate global rate system. examine influential role following parameters on system, viz., parameter (eDe2), Debye–Huckel κ ¯ , channel wall thickness (δ), conductivity (γ), Biot number (Bi), Peclet (Pe), axial temperature gradient (B). This investigation finally establishes optimum values abovementioned parameters, leading minimum believe that results thi...
