Title

Momentum, energy and vorticity balances in deep-water surface gravity waves.

Abstract

The article in the Journal of Fluid Mechanics, published on October 25, 2024, examines momentum, energy, and vorticity balances in deep-water surface gravity waves. It discusses particle trajectories in irrotational, incompressible, and inviscid deep-water surface gravity waves, emphasizing the role of Stokes drift in surface wave-induced mixing in the ocean. The research explores the relationship between momentum density, kinetic energy density, and vorticity for two-dimensional water waves, highlighting conservation principles in the system. Additionally, the study investigates the connection between Lagrangian drift, water level, and dynamics, shedding light on wave-induced mean Lagrangian flow for irrotational surface gravity waves.
