Seminars
Regular seminars are held on Fridays at the scientific council of the Landau Institute in Chernogolovka. Also joint ITP - Chinese Academy of Sciences online colloquium is held online.
Departments of the institute hold their own seminars; the topic are determined by the scientific orientation of the related department.
Seminars information is also sent via e-mail. If you want to receive seminar announcements, please subscribe.
Motion of neutrally buoyant particles in a turbulent fluid
20 June in 12:30 at scientific council (short)
Masnev N.G.
We investigate analytically and numerically the statistical properties of the dynamics of rigid spherical particles with neutral buoyancy.
The particles are placed in a turbulent flow with a strong shear component. As a simple model, we consider the shear flow of an axisymmetric vortex with turbulent fluctuations and calculate the particle distribution from the distance to the vortex center. We present quantitative results obtained within the framework of a point particle model with fluctuations that are correlated in time.
