Simulations of flow separation control numerically using different plasma actuator models

Flow Control of Leading Edge Separation on Airfoil Using Dbd Plasma Actuator

Sensing and control of flow separation using plasma actuators.

Single dielectric barrier discharge plasma actuators have been used to control flow separation in a large number of applications. An often used configuration involves spanwise-oriented asymmetric electrodes that are arranged to induce a tangential wall jet in the mean flow direction. For the best effect, the plasma actuator is placed just upstream of where the flow separation will occur. This a...

experimental investigation of active flow control for changing stall angle of a naca0012 airfoil, using plasma-actuator

active flow control has great importance in design of flying objects in general and control flaps in particular. using dielectric barrier discharge as plasma actuators over control flaps can cause a change in position of separation point or can eliminate it. this new flow control device produces a body force that causes generating a micro wall jet. the present study aims to investigate experime...

Flow Control over Conical Forebody with Port Pulsed Plasma Actuator

A study using plasma port single-pulsed discharge is performed on the flow control of asymmetrical vortices over slender conical forebody. The different circumferential steady and unsteady pressure distributions are measured in the wind tunnel test. At the same time, the local side force, the increment of local side force and the overall side force and moment are calculated with the circumferen...

Numerical and Experimental Analysis of Plasma Flow Control Over a Hump Model

Turbulent flow separation over a wall-mounted hump model and its control using plasma actuators were studied numerically and experimentally. The hump model chosen in this study was that used in a 2004 NASA Langley CFD validation workshop for turbulent separation control using synthetic jets. The numerical simulations solved the Reynoldsaveraged Navier-Stokes equations using Fluent. Different tu...
