Porous media pressure distribution in centrifugal fields

Abstract

The simplest use of centrifuges to measure soil properties relies on steady state conditions. Analytical solutions, especially if they are simple, make interpretation of data more direct and transparent. Previous approximations are simplified and have a greatly improved accuracy. Using previous examples as a test, the error on pressure is always less than 1%, compared to about 10% with previous approximations. Key Points using centrifuges to measure soil water conductivity for steady state conditions analytical solutions are obtained to interpret data directly and transparently error on pressure is less than 1% instead of 10% with previous solution
