Material point method applied to multiphase flows
The particle-in-cell method (PIC), especially the latest version of it, the material point method (MPM), has shown significant advantage over the pure Lagrangian method or the pure Eulerian method in numerical simulations of problems involving large deformations. It avoids the mesh distortion and tangling issues associated with Lagrangian methods and the advection errors associated with Euleria...
متن کاملMaterial Science
• Optical property of a material is defined as its interaction with electro-magnetic radiation in the visible. • Electromagnetic spectrum of radiation spans the wide range from γ-rays with wavelength as 10 m, through x-rays, ultraviolet, visible, infrared, and finally radio waves with wavelengths as along as 10 m. • Visible light is one form of electromagnetic radiation with wavelengths ranging...
متن کاملTarget material dependence of secondary electron images induced by focused ion beams
Monte Carlo calculation of ion-induced kinetic secondary electron emission was performed to study the target material dependence of secondary electron images in scanning ion microscopy (SIM) by using focused ion beams, which is different from that in scanning electron microscopy (SEM). In the calculation, the electron excitation by projectile ions is treated using the partial wave scattering cr...
متن کاملPure Science and Applied Science*
The name of my talk is Pure Science and Applied Science, and the idea I would like to sell to you today is that there is no such thing as “pure” or “applied” science. In other words, there is such a thing as science, but there is no difference between pure and applied science. Science is one entity and cannot be separated into different categories. In order to back that up, I would like to tell...
متن کاملRelativistic electron beams above thunderclouds
Non-luminous relativistic electron beams above thunderclouds have been detected by the radio signals of low frequency ∼40–400 kHz which they radiate. The electron beams occur ∼2–9 ms after positive cloud-to-ground lightning discharges at heights between ∼22–72 km above thunderclouds. Intense positive lightning discharges can also cause sprites which occur either above or prior to the electron b...
