A statistical description of turbulence comprising a probability distribution for stationary flows is the basis determining nature turbulent velocity fluctuations. Away from Eulerian spatial increments field, Lagrangian notion temporal along particle trajectories appears to be hob statistics, ostensibly in presence inherent intermittencies observable tracking. Such were analyzed by using well-k...
Most of the current ash transport and dispersion models neglect particle-fluid (two-way) and particle-fluid plus particle-particle (four-way) reciprocal interactions during particle fallout from volcanic plumes. These interactions, a function of particle concentration in the plume, could play an important role, explaining, for example, discrepancies between observed and modelled ash deposits. A...
Two optical techniques are experimentally investigated to measure the shock wave velocity and particle velocity in metals subjected to hyper velocity impacts. Fabry-Perot interferometer based optical system has been developed and used to measure the interface velocity profile of impacted Tantalum-Glass and Aluminum-Glass targets. Optical fibers coupled to fast photodiodes are implemented to mea...
We discuss the definition of particle velocity in doubly relativity theories. The general formula relating velocity and fourmomentum of particle is given. ∗supported by KBN grant 2 P03B 134 16
