Model-based design of riblets for turbulent drag reduction
Wei Ran, Armin Zare, Mihailo R. Jovanović
Both experiments and direct numerical simulations have been used to demonstrate that riblets can reduce turbulent drag by as much as , but their systematic design remains an…
Stochastic receptivity analysis of boundary layer flow
Wei Ran, Armin Zare, M. J. Philipp Hack +1
We utilize the externally forced linearized Navier-Stokes equations to study the receptivity of pre-transitional boundary layers to persistent sources of stochastic excitation. Sto…
Modeling mode interactions in boundary layer flows via the Parabolized Floquet Equations
Wei Ran, Armin Zare, M. J. Philipp Hack +1
In this paper, we develop a model based on successive linearization to study interactions between different modes in boundary layer flows. Our method consists of two steps. First,…
Free Energy of the Cauchy Directed Polymer Model at High Temperature
Ran Wei
We study the Cauchy directed polymer model on , where the underlying random walk is in the domain of attraction to the -stable law. We show that, if the random…
On the Long-range Directed Polymer Model
Ran Wei
We study the long-range directed polymer model on $\mathbbm{Z}$ in a random environment, where the underlying random walk lies in the domain of attraction of an -stable process…
Theory of Bosons in two-leg ladders with large magnetic fields
Ran Wei, Erich J. Mueller
We calculate the ground state of a Bose gas trapped on a two-leg ladder where Raman-induced hopping mimics the effect of a large magnetic field. In the mean-field limit, where ther…
Vortex structures of a two-component BEC for large anisotropies
Ran Wei, Erich Mueller
We calculate the vortex structures of an elongated two-component Bose-Einstein condensate. We study how these structures depend on the intra-component and inter-component interacti…
