Active Flow Control on Vertical Tail Models [PDF]

open access: yesAIAA Journal, 2019
Active flow control (AFC) subscale experiments were conducted at the Lucas Wind Tunnel of the California Institute of Technology. Tests were performed on a generic vertical tail model at low speeds. Fluidic oscillators were used at the trailing edge of the main element (vertical stabilizer) to redirect the flow over the rudder and delay or prevent flow

Centrifugation-assisted lateral flow assay platform: enhancing bioassay sensitivity with active flow control [PDF]

open access: yesMicrosystems & Nanoengineering
Lateral flow assays (LFAs) are widely used in point-of-care testing (POCT) due to their simplicity and rapid operation. However, their reliance on passive capillary flow limits sensitivity, making it challenging to detect low-abundance biomarkers ...

Active Flow Control on a Square-Back Road Vehicle

open access: yesFluids, 2020
An experimental investigation focused on the manipulation of the wake generated by a square back car model is presented. Four continuously-blowing rectangular slot jets were mounted on the rear face of a 1:10 commercial van model.

Active control of hydrodynamic slug flow [PDF]

open access: yes, 2013
Multiphase flow is associated with concurrent flow of more than one phase (gas-liquid, liquid-solid, or gas-liquid-solid) in a conduit. The simultaneous flow of these phases in a flow line, may initiate a slug flow in the pipeline. Hydrodynamic slug flow

Active Flow Control for Helicopters

open access: yes, 2013
Several active flow control helicopter applications aimed at improving aerodynamic performance have been studied at Onera and are presented in this paper. The distinction between applications for non-rotating or non-lifting parts and for rotating parts is presented.

Effects of Simultaneous Suction and Blowing over an Airfoil on Flow Behavior and Aerodynamic Coefficients [PDF]

open access: yesIranica Journal of Energy and Environment, 2022
In this study, the simultaneous effect of suction and blowing on the boundary layer and the effect of control parameters on the flow separation from a NACA 0012 airfoil is numerically analyzed.

Gym-preCICE: Reinforcement learning environments for active flow control

open access: yesSoftwareX, 2023
Active flow control (AFC) involves manipulating fluid flow over time to achieve a desired performance or efficiency. AFC, as a sequential optimisation task, can benefit from utilising Reinforcement Learning (RL) for dynamic optimisation. In this work, we

Flow Separation Control on NACA0015 Airfoil Using Synchronized Jet Actuator [PDF]

open access: yesJournal of Applied Fluid Mechanics, 2022
In this study, a novel fluidic jet actuator is designed to control flow separation on a NACA0015 airfoil at various angles of attack. The U-shaped jet actuator has two rectangular slots implemented near the leading edge of the airfoil.
