Vergniolle, Sylvie, 2024, "Codes for calculating the degassing parameters in the reservoir at Shishaldin volcano", https://doi.org/10.18715/IPGP.2023.lj5wjhw6, IPGP Research Collection, V1
Three sets of functions written in Matlab are in this folder. The functions have been written by S. Vergniolle, Institut de physique de Paris, France (June 2023) for the submission of a paper on volcanology, and more specifically on the 1999 eruption at Shishaldin (Alaska) for JG...
MATLAB Source Code - 2.3 KB - MD5: dac787fe75579185c3340c360133197e
A matlab function which estimates the gas volume fraction within the foam from the value of its ratio, expressed in paper
MATLAB Source Code - 988 B - MD5: ee2a203338761a0f728aa15ed23542e6
This function estimates the ratio of gas volume fraction, existing in the Kozeny’s equation, from the measured value of the drainage velocity (Kozeny velocity) within a foam
MATLAB Source Code - 28.3 KB - MD5: 8f2cde66313fc21cc83734ee48339694
This matlab script contains the values of the experimental data points and estimates the drainage velocity for three initial gas fluxes
MATLAB Source Code - 4.1 KB - MD5: 52cf5579c77882e076cd7555446afc99
This matlab code estimate the magma viscosity from magma compositions (strongly adapted from Giordano’s code, 2008)
MATLAB Source Code - 31.6 KB - MD5: 837606f79dca6b381dff4defc8b6f52a
The fourth set of functions is used to estimate the parameters of the degassing reservoir, bubble diameter, reservoir radius, geometrical coefficient, the diameter of the bubble clusters and their errors. The errors are calculated by selecting each parameter within a Gaussian dis...
MATLAB Source Code - 14.0 KB - MD5: f10dcb63dc103fffe61849b4763a3dcd
A matlab function to calculate the gas volume fraction in the foam in the conduit with a sensitivity analysis performed by a random sampling with Monte-Carlo of the entry parameters within a Gaussian distribution
