Three-Dimensional Fluctuating Flow of a Second-Grade Fluid along an Infinite Horizontal Plate with Periodic Suction

Laminar flow control plays a vital role in reducing drag resulting enhancement the vehicle power by significant amount. Theoretical and experimental studies have proven that transition from laminar to turbulent (causing coefficient enhance) may be delayed/prevented suction of fluid boundary layer wall. The purpose this work is study effects periodic on unsteady 3-dimensional fluctuating second grade incompressible flowing laminarly over horizontal porous infinite plate. plate subjected sinusoidal transverse velocity while free stream oscillates time about constant mean. turns out because direction velocity. By series expansion method, analytic expressions for transient velocity, skin friction components, pressure are attained. Impact nondimensional parameters evolving mathematical model problem these physical quantities visualized graphically discussed analytically. component u found rising with growth parameter α. noted growing Reynolds number R e . Further, due at increases near then reaches steady value far-off along main noticed decreasing rise id="M2"> α id="M3"> 0.5 ≤ 1.4 , however, an exponential observed id="M4"> > 1.4. cross enhancing values elastic parameter. present results excellent agreement previous published limiting sense. This beneficial designing manufacturing system enhance requirement.
