Navier-Stokes equations in cylindrical coordinates
17 Dec 2016 | Contributor(s): Mattia de' Michieli Vitturi
This document presents the derivation of the Navier-Stokes equations in cylindrical coordinates. I have searched on the web for something similar (and I have seen that a lot of other people search for the steps of such a derivation), but I have been unsuccessful. For this reason I have thought...

A 2D non linear diffusion code is by Mattia de' Michieli Vitturi (Istituto Nazionale di Geofisica e Vulcanologia, Sezione di Pisa).This code solve for the nonlinear diffusion problem dh/dt = div( f(h) grad(h) )wheref(h) = k * ( 1 + ( max_nlc -1 ) * ( |grad(h)| / S_c )^n )k is...

PlumeMoM is a numerical code for the steady-state plume model, describing the rise in the atmosphere of a mixture of gas and volcanic ash during an eruption. The system of equation is formally the same of that presented in Barsotti et al. 2008, i.e. the equations we formulate describe the same...
