We present an analytical solution of plane motion for a Bingham fluid initially at rest subjected to a suddenly applied constant pressure gradient. Using the Laplace transform expressions are obtained, which allow a direct calculation of the velocity, of the plug thickness and of tyhe rate of flow as function of time.

Abstract
We present an analytical solution of plane motion for a Bingham fluid initially at rest subjected to a suddenly applied constant pressure gradient. Using the Laplace transform expressions are obtained, which allow a direct calculation of the velocity, of the plug thickness and of tyhe rate of flow as function of time.File in questo prodotto:
