Aging and memory of transitional turbulence
Vasudevan Mukund, Chaitanya S. Paranjape, Michael Philip Sitte +2
The recent classification of the onset of turbulence as a directed percolation (DP) phase transition has been applied to all major shear flows including pipe, channel, Couette and…
An autonomous compartmental model for accelerating epidemics
Nazmi Burak Budanur, Björn Hof
In Fall 2020, several European countries reported rapid increases in COVID-19 cases along with growing estimates of the effective reproduction rates. Such an acceleration in epidem…
Experimental observation of the origin and structure of elasto-inertial turbulence
George H. Choueiri, Jose M. Lopez, Atul Varshney +2
Turbulence generally arises in shear flows if velocities and hence inertial forces are sufficiently large. In striking contrast, viscoelastic fluids can exhibit disordered motion e…
Symmetry-reduced Dynamic Mode Decomposition of Near-wall Turbulence
Elena Marensi, Gökhan Yalnız, Björn Hof +1
Data-driven dimensionality reduction methods such as proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD) have proven to be useful for exploring complex pheno…
