Predicting the role of inequalities on human mobility patterns
Alain Boldini, Pietro De Lellis, Salvatore Imperatore +4
Whether in search of better trade opportunities or escaping wars, humans have always been on the move. For almost a century, mathematical models of human mobility have been instrum…
Data-driven model for Lagrangian evolution of velocity gradients in incompressible turbulent flows
Rishita Das, Sharath S. Girimaji
Velocity gradient tensor, , in a turbulence flow field is modeled by separating the treatment of intermittent magnitude ($A = \sqrt{A_{ij}A_…
Local vortex line topology and geometry in turbulence
Bajrang Sharma, Rishita Das, Sharath S. Girimaji
The local streamline topology classification method of Chong et al. (1990) is adapted and extended to describe the geometry of infinitesimal vortex lines. Direct numerical simulati…
Characterization of velocity-gradient dynamics in incompressible turbulence using local streamline geometry
Rishita Das, Sharath S. Girimaji
This study develops a comprehensive description of local streamline geometry and uses the resulting shape features to characterize velocity gradient () dynamics. The local…
Revisiting turbulence small-scale behavior using velocity gradient triple decomposition
Rishita Das, Sharath S. Girimaji
Turbulence small-scale behavior has been commonly investigated in literature by decomposing the velocity-gradient tensor () into the symmetric strain-rate () and an…
