Stochastic models of Lagrangian acceleration of fluid particle in developed turbulence
A. K. Aringazin, M. I. Mazhitov
Modeling statistical properties of motion of a Lagrangian particle advected by a high-Reynolds-number flow is of much practical interest and complement traditional studies of turbu…
Conditional Lagrangian acceleration statistics in turbulent flows with Gaussian distributed velocities
A. K. Aringazin
The random intensity of noise approach to one-dimensional Laval-Dubrulle-Nazarenko type model having deductive support from the three-dimensional Navier-Stokes equation is used to…
Design of Mathematical Model for Prediction of Bar at Strain-Heat Hardening
A. A. Kanayev
About designing of mathematical model for forecasting of mechanical properties of hypopearlite steels both hot-rolled and strain-heat hardened state.
One-dimensional Langevin models of fluid particle acceleration in developed turbulence
A. K. Aringazin, M. I. Mazhitov
We make a comparative analysis of some recent one-dimensional Langevin models of the acceleration of a Lagrangian fluid particle in developed turbulent flow. The class of models ch…
The PDF of fluid particle acceleration in turbulent flow with underlying normal distribution of velocity fluctuations
A. K. Aringazin, M. I. Mazhitov
We describe a formal procedure to obtain and specify the general form of a marginal distribution for the Lagrangian acceleration of fluid particle in developed turbulent flow using…
Two-dimensional tunnel correlations with dissipation
A. K. Aringazin, Yu. Dahnovsky, V. D. Krevchik +3
Tunneling of two particles in synchronous and asynchronous regimes is studied in the framework of dissipative quantum tunneling. The critical temperature T_c corresponding to a bif…
