Damage Detection in a laboratory-scale wellbore applying Time Reverse Nonlinear Elastic Wave Spectroscopy (TR NEWS)
Erin Dauson, Carly Donahue, Scott DeWolf +4
Time Reverse Nonlinear Elastic Wave Spectroscopy (TR-NEWS) has been used to focus acoustic energy, and make measurements correlated with damage in a variety of industrial materials…
Scaling of Erosion Rate in Subsonic Jet Experiments and Apollo Lunar Module Landings
Philip T. Metzger, John E. Lane, Christopher D. Immer +5
Small scale jet-induced erosion experiments are useful for identifying the scaling of erosion with respect to the various physical parameters (gravity, grain size, gas velocity, ga…
Cratering of Soil by Impinging Jets of Gas, with Application to Landing Rockets on Planetary Surfaces
Philip T. Metzger, Bruce T. Vu, D. E. Taylor +9
Several physical mechanisms are involved in excavating granular materials beneath a vertical jet of gas. These occur, for example, beneath the exhaust plume of a rocket landing on…
