1. Navier-Stokes equations in cylindrical coordinates

   out of 5 stars 

   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...

   Cyclicity at active volcanoes is commonly observed and interpreted to reflect periods of vesiculation and gas pressurisation beneath more dense degassed plugs. In 1997, Vulcanian eruptions from Soufrière Hills volcano (SHV), Montserrat, had a mean repose time of 9.5 hours. We consider the...

   An introductory lecture about a pair of related volcanoes in Guatemala, Santa Maria and Santiaguito. Meant to help orient researchers on this great laboratory volcano. The first part of the lecture is followed by Part 2, which in in the supporting documents.Escobar Wolf, R, RO Matias Gomez and WI...

5. Conflow 1.0.5

   01 Feb 2011 | | Contributor(s):: Larry Garver Mastin

   Conflow is a user-friendly program that calculates flow properties of magma-gas mixtures through eruptive conduits during steady explosive volcanic eruptions. It also calculates physical and thermodynamic properties of magma-gas-crystal mixtures. The attached zip file installs the program on any...
