# 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.

# Combustor

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.

# Jet

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.
