Updated Numerical Analysis Benchmarks for Meteoroid Relevant MaterialsProposal for update of numerical analysis benchmark for meteoroid relevant materials.
- Two recently performed shots are proposed to be numerical analysis benchmarks for numerical simulations of impacts of high-density meteoroids (Al2O3surrogate) and low-density meteoroids (Nylon surrogate).
- A pair of general Whipple shields have been studied:
- Bumper and rear walls are the same material and thickness between shields
- Separation is 4.5 cm for Al2O3and 1.5 cm for Nylon
- Information gathered includes high speed (1 MHz) shadowgraphs of debris cloud, bumper hole size and rear wall hole area.
