Ultrasonic drying of saturated porous solids via second sound
First Claim
Patent Images
1. A method for drying a porous solid having a predefined particle size saturated with a fluid comprising the steps of:
- subjecting the porous solid saturated to an ultrasonic signal to release the fluid from the porous solid saturated, said subjecting step includes applying a predefined acoustic slow wave frequency based upon the predefined particle size in said porous solid saturated thereby causing the fluid to move from an interior of said porous solid saturated to an outer surface of said porous solid saturated, where fluid can be removed; and
removing the fluid from said saturated porous solid.

Abstract
A method for drying a porous solid saturated with a fluid including the steps of subjecting the saturate porous image to an ultrasonic signal to release the fluid from the saturated porous image layer; removing the fluid from said saturated porous solid, said subjecting step includes applying a predefined acoustic slow wave frequency based upon the particle sizes in said porous image layer thereby causing the fluid to move from an interior of said porous particulate image to an outer surface of said porous image, where fluid can be removed by conventional image.
