Limiting regimes of turbulent horizontal convection. Part II : Large Prandtl numbers
Pierre-Yves Passaggia, Nadia F. Cohen, Alberto Scotti +1
Horizontal Convection (HC) at large Rayleigh and Prandtl numbers, is studied experimentally in a regime up to seven orders of magnitude larger in terms of Rayleigh numbers than pre…
Limiting regimes of turbulent horizontal convection. Part I: Intermediate and low Prandtl numbers
Pierre-Yves Passaggia, Alberto Scotti, Brian L. White
We report the existence of two new limiting turbulent regimes in horizontal convection (HC) using direct numerical simulations at intermediate to low Prandtl numbers. The flow driv…
Heat and momentum transport in turbulent horizontal convection at low Prandtl numbers
Pierre-Yves Passaggia, Alberto Scotti, Brian L. White
The transition to a new turbulent regime in horizontal convection in the case of low Prandtl numbers is analyzed using the Shishkina, Grossmann & Lohse (SGL) theory. The flow drive…
A local diagnostic energy to study diabatic effects on a class of degenerate Hamiltonian systems with application to mixing in stratified flows
Alberto Scotti, Pierre-Yves Passaggia
In Hamiltonian systems characterized by a degenerate Poisson algebra, we show how to construct a local energy-like quantity that can be used to study diabatic effects on the evolut…
Fluid dynamics in the spirit of Cartan: A coordinate-free formulation of fluid dynamics for an inviscid fluid in inertial and non-inertial frames
Alberto Scotti
Using Cartan's exterior calculus, we derive a coordinate-free formulation of the Euler equations. These equations are invariant under Galileian transformations, which constitute a…
An Efficient Method For Solving Highly Anisotropic Elliptic Equations
Edward Santilli, Alberto Scotti
Solving elliptic PDEs in more than one dimension can be a computationally expensive task. For some applications characterised by a high degree of anisotropy in the coefficients of…
