Turbulence on Hybrid Lattices: regular grids meet self similar cascade models
Lorenzo Manfredini, Özgür D. Gürcan, Sai Swetha Venkata Kolluru +1
Turbulent cascades in high Reynolds number regimes span many decades in scale, which can be challenging for numerical simulations. Cascade models that use logarithmic discretizatio…

Complex-time singular structure of the 1D Hou-Luo model
Cornelius Rampf, Sai Swetha Venkata Kolluru
Starting from smooth initial data, we investigate the complex-time analytic structure of the one-dimensional Hou--Luo (HL) model, a wall approximation of the three-dimensional axis…
