Diffusion-limited settling of highly porous particles in density-stratified fluids
Robert Hunt, Roberto Camassa, Richard M. McLaughlin +1
The vertical transport of solid material in a stratified medium is fundamental to a number of environmental applications, with implications for the carbon cycle and nutrient transp…
Simple two-layer dispersive models in the Hamiltonian reduction formalism
R. Camassa, G. Falqui, G. Ortenzi +2
A Hamiltonian reduction approach is defined, studied, and finally used to derive asymptotic models of internal wave propagation in density stratified fluids in two-dimensional doma…
Tauberian identities and the connection to Wile E. Coyote physics
Roberto Camassa, Richard M. McLaughlin
The application of the motion of a vertically suspended mass-spring system released under tension is studied focusing upon the delay timescale for the bottom mass as a function of…
Critical density triplets for the arrestment of a sphere falling in a sharply stratified fluid
Roberto Camassa, Lingyun Ding, Richard M. McLaughlin +3
We study the motion of a rigid sphere falling in a two-layer stratified fluid under the action of gravity in the potential flow regime. Experiments at a moderate Reynolds number of…
Evolution of interface singularities in shallow water equations with variable bottom topography
R. Camassa, R. D'Onofrio, G. Falqui +2
Wave front propagation with non-trivial bottom topography is studied within the formalism of hyperbolic long wave models. Evolution of non-smooth initial data is examined, and in p…
Numerical Algorithms for Water Waves with Background Flow over Obstacles and Topography
David M. Ambrose, Roberto Camassa, Jeremy L. Marzuola +3
We present two accurate and efficient algorithms for solving the incompressible, irrotational Euler equations with a free surface in two dimensions with background flow over a peri…
