Vibrational Liquefaction of Concentrated Suspensions.

The principles of vibrational liquefaction is briefly described and several examples of its possible application are pointed out. Simple modifications of the outflow rheometer and penetrometer are proposed. Approximations are proposed for the description of the rheological behavior of a real suspension by means of a simple rheological model. A quantitative measure of liquefaction can be then determined from the definition of a liquefaction coefficient proposed. A table is presented which facilitates the estimation of this parameter in simple situations.
