Abstract
THE COLLAPSE OF A STEAM BUBBLE IN A POOL OF SUBCOOLED WATER IS KNOWN TO RESULT IN THE RADIATION OF PRESSURE WAVES OF ENORMOUS MAGNITUDE. THESE PRESSURE WAVES CAN BE USED TO FRACTURE MATERIALS AND/OR REMOVE MATERIAL IF THEY CAN BE DIRECTED. DEVELOPMENT OF A NOZZLE IS PROPOSED WHICH WILL DIRECT COLLAPSING STEAM BUBBLES TOWARDS A SURFACE AND SET UP STRESS WAVES IN THE SOLID WHICH WILL RESULT IN SURFACE CLEANING. THE NOZZLE SERVES A SECOND PURPOSE IN CARRYING AWAY SHARDS OF MATERIAL WHICH HAVE BEEN REMOVED FROM THE SURFACE. IT IS ANTICIPATED THAT THE ABOVE DEVICE, WHEN PERFECTED, COULD BE USED TO REMOVE ANY AFIXED MATERIAL WITHOUT DEGRADING THE MECHANICAL, CHEMICAL OR PHYSICAL PROPERTIES OF THE SURFACE TO WHICH IT IS ATTACHED.
