Nonlinear shallow water dynamics with odd viscosity

Year: 2021

Type: article

Abstract: The concept of an ``odd'' coefficient of viscosity appears in some fluid mechanical contexts, including quantum fluids, electron fluids in mesoscopic systems, as well as some classical systems. Here we study the shallow depth limit of weakly nonlinear surface dynamics with odd viscosity and gravitational effects and obtain an integrable Kortweg-de Vries equation, the solution of which admits right- and left-moving disturbances with some differences. The odd viscosity term plays a role similar to surface tension.
