TLDR
In this paper, a flow density transducer and a pressure or velocity transducers are used to measure flow velocity during air blast peening with predetermined desired values, and the operation of the apparatus is automatically adjusted by adjustment of flow density and/or flow velocity to maintain these parameters at desired values.Abstract:
Air blast peening equipment includes a flow density transducer and a pressure or velocity transducer for measuring flow velocity. Measured values are compared during peening with predetermined desired values. Operation of the apparatus is automatically adjusted, if necessary, by adjustment of flow density and/or flow velocity to maintain these parameters at desired values.read more

Method and apparatus for drilling small diameter holes in fragile material with high velocity liquid jet
TL;DR: In this paper, an abrasive-jet drilling system is described for small diameter holes in fragile materials of the type which tend to crack when impacted by such jets. But the system employs a drilling jet formed from a high pressure liquid whose pressurization varies with time during the drilling process.
