Numerical Computation of Pressure Distributions over Conical Forebody at High Angles of Attack
Pressure distributions over a 20° conical forebody are computed by the commercial CFD software ANSYS CFX. Free stream velocity is 30 m/s, Reynolds number based on the forebody base diameter is 0.3×10 6 , and the angle of attack ranges from 10° to 35°. The C-O structural grids are used to compute the entire flow field. The governing equations are steady Reynolds-Averaged Navier-Stokes Equations ...
متن کاملComputational fluid dynamics simulation of the flow patterns and performance of conventional and dual-cone gas-particle cyclones
One of the main concerns of researchers is the separation of suspended particles in a fluid. Accordingly, the current study numerically investigated the effects of a conical section on the flow pattern of a Stairmand cyclone by simulating single-cone and dual-cone cyclones. A turbulence model was used to analyze incompressible gas-particle flow in the cyclone models, and the Eulerian–Lagrangian...
متن کاملFlow 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...
متن کاملEffect of plasma actuation on asymmetric vortex flow over a slender conical forebody
The active flow control technology by using plasma actuation to manipulate forebody vortices on a slender conical body is being studied based on the previous research. This work is motivated by the need to increase the experimental velocity in the wind tunnel via an effective streamlining created by the actuators. A pair of Single-Dielectric Barrier Discharge (SDBD) plasma actuators is installe...
