POD analysis of flow over a backward-facing step forced by right-angle-shaped plasma actuator
PURPOSE This study aims to present flow control over the backward-facing step with specially designed right-angle-shaped plasma actuator and analyzed the influence of various scales of flow structures on the Reynolds stress through snapshot proper orthogonal decomposition (POD). METHODS 2D particle image velocimetry measurements were conducted on region (x/h = 0-2.25) and reattachment zone in...
متن کاملSimulation of Steady, Laminar Flow Over a Backward-Facing Step
A 2D Navier-Stokes solver was developed to simulate steady,laminar flow over a backward-facing step of height h. The step expansion ratio=1/2 and the flow at the step was assumed to be fully developed, laminar channel flow. The Reynolds number for this flow was defined as Re=Uh/ν. The 2D incompressible Navier-Stokes equations was solved in generalized curvilinear coordinates using artificial co...
متن کاملDirect numerical simulation of compressible flow over a backward-facing step
In this paper, we perform a direct numerical simulation study to investigative the effect of compressibility on the flow over a backward-facing step. A spectral multidomain method is used for simulating the compressible flow at Reynolds number of 3000 over an open backward-facing step. The role of compressibility in the sub-sonic regime is studied by simulating the flow at different free-stream...
متن کاملNumerical Simulation of Mixed Convective Flow Over a Three-Dimensional Horizontal Backward Facing Step
Laminar mixed convective flow over a three-dimensional horizontal backward-facing step heated from below at a constant temperature was numerically simulated using a finite volume technique and the most relevant hydrodynamic and thermal features for air flowing through the channel are presented in this work. The channel considered in this work has an aspect ratio AR=4, and an expansion ratio ER=...
متن کاملNumerical simulation of laminar to turbulent nanofluid flow and heat transfer over a backward-facing step
This paper presents a numerical study of heat transfer to turbulent and laminar Cu/water flow over a backward-facing step. Mathematical model based on finite volume method with a FORTRAN code is used to solve the continuity, momentum, energy and turbulence equations. Turbulence was modeled by the shear stress transport (SST) K–x Model. In this simulation, three volume fractions of nanofluid (0%...
