Fluidic pinball --- a toolkit for exploring multiple-input multiple-output flow control.
EGM is applied to the minimization of the parasitic net drag power of the multi-input fluidic pinball problem. It yields a slightly asymmetric boat-tailing actuation with \(29\%\) net drag power reduction comprising \(52\%\) drag reduction penalized by \(23\%\) actuation energy. See Journal of Fluid Mechanics, 932, A7 for more details.
Ahmed body --- a generic low-drag vehicle model
EGM reduces the drag of an \(35^\circ\) slanted Ahmed body by \(17\%\) with independent steady blowing at all trailing edges at Reynolds number \(Re_H = 1.9 \times 10^5\). The \(10\)-dimensional actuation space includes \(5\) symmetric jet slot actuator groups with variable velocity and variable blowing angle. The resulting drag is computed with a Reynolds-Averaged Navier-Stokes (RANS) simulation and verified with Large Eddy Simulation (LES). See Journal of Fluid Mechanics, 932, A7 for more details.
EGM is applied to a generic low-order thermoacoustic can-combustor model with five fuel injectors to minimize pressure pulsation amplitudes. See ASME. J. Eng. Gas Turbines Power, August, 2021 for more details.
We build a jet with distributed minijets based on an in home solver developed by Artur Tyliszczak. Here are unforced and forced flows found by EGM for mixing enhancement.
