Optimisation of Transonic Circulation Control Devices [PDF]
, 2015 Gradient based optimisation of a Coanda surface for a transonic, supercritical circulation control aerofoil is presented. Design variable updates are driven by a Sequential Least Squares Quadratic Programming (SLSQP) algorithm, using gradients provided ...

Function of the turbo‐sail airfoil applied to the Darrieus wind turbine
Wind Energy, Volume 27, Issue 5, Page 483-499, May 2024.Abstract The use of a turbo‐sail airfoil to improve the power generation of a Darrieus wind turbine was examined. The turbo‐sail airfoil comprises a symmetric blade from which a high‐speed tangential jet is produced to suppress flow separation. For a steady angle of attack, we experimentally confirmed an anti‐stall function of the airfoil at an angle ...

Navier-Stokes computations for circulation control airfoils [PDF]
Navier-Stokes computations of subsonic to transonic flow past airfoils with augmented lift due to rearward jet blowing over a curved trailing edge are presented. The approach uses a spiral grid topology.

Journal of Phycology, Volume 60, Issue 1, Page 73-82, February 2024.Abstract Culturing kelps for commercial, conservation, and scientific purposes is becoming increasingly widespread. However, kelp aquaculture methods are typically designed for ocean‐based farms, and these methods may not be applicable for smaller scale cultivation efforts common in research and restoration.

Investigation of terrain slope effects on wind enhancement by a line source fire
Case Studies in Thermal Engineering, 2019 Wind enhancement triggered by fire-wind interaction can potentially pose significant damage to structures built in bushfire prone areas. The effect of terrain slope is one of the parameters contributing to the enhancement of wind by fire that needs to be

Design of supersonic Coanda jet nozzles [PDF]
The thrust vectoring of supersonic Coanda jets was improved by designing a nozzle to skew the initial jet velocity profile. A new nozzle design procedure, based on the method of characteristics, was developed to design a nozzle which produces a specified

COANDA SURFACE EFFECT ON THE SWEEPING JET ACTUATOR
Havacılık ve Uzay Teknolojileri Dergisi, 2018 A sweeping jet (SWJ) actuator emits a continuous but spatially oscillating jet when pressurized with a fluid. In this study, unsteady flow fields generated by a SWJ actuator are investigated using two-dimensional, unsteady, Reynolds-Averaged Navier ...
