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…
Jet-induced cratering of a granular surface with application to lunar spaceports
Philip T. Metzger, Christopher D. Immer, Carly M. Donahue +3
The erosion of lunar soil by rocket exhaust plumes is investigated experimentally. This has identified the diffusion-driven flow in the bulk of the sand as an important but previou…
Craters Formed in Granular Beds by Impinging Jets of Gas
Philip T. Metzger, Robert C. Latta, Jason M. Schuler +1
When a jet of gas impinges vertically on a granular bed and forms a crater, the grains may be moved by several different mechanisms: viscous erosion, diffused gas eruption, bearing…
