Abstract:  
Academic Study by Dr. David Kirk INTRODUCTION A particular shot stream should always be regarded as a combination of shot particles carried along in a stream of fluid. The fluid is normally air but is sometimes water and could, conceivably, be any one of many other fluids. Shot streams differ from one another in terms of their average peening intensity. The principal causes of this difference are generally well-understood being: shot size, velocity and density. An independent increase in any one of those parameters will increase the average peening intensity. The measured peening intensity for one particular shot stream is not, however, constant
