Effective Drift Velocity from Turbulent Transport by Vorticity
Hussein Aluie, Shikhar Rai, Hao Yin +5
We highlight the differing roles of vorticity and strain in the transport of coarse-grained scalars at length-scales larger than by smaller scale (subscale) turbulence. %sub…
Scaling of Turbulent Viscosity and Resistivity: Extracting a Scale-dependent Turbulent Magnetic Prandtl Number
Xin Bian, Jessica K. Shang, Eric G. Blackman +2
Turbulent viscosity and resistivity are perhaps the simplest models for turbulent transport of angular momentum and magnetic fields, respectively. The associated turbul…
Revisiting the Late-Time Growth of Single-mode Rayleigh-Taylor Instability and the Role of Vorticity
Xin Bian, Hussein Aluie, Dongxiao Zhao +2
Growth of the single-fluid single-mode Rayleigh-Taylor instability (RTI) is revisited in 2D and 3D using fully compressible high-resolution simulations. We conduct a systematic ana…
Baropycnal Work: A Mechanism for Energy Transfer Across Scales
Aarne Lees, Hussein Aluie
The role of baroclinicity, which arises from the misalignment of pressure and density gradients, is well-known in the vorticity equation, yet its role in the kinetic energy budget…
Decoupling of the Kinetic and Magnetic Energy Cascades in MHD Turbulence
Xin Bian, Hussein Aluie
Magnetic and kinetic energy in ideal incompressible MHD are not global invariants and, therefore, it had been justified to discuss only the cascade of their sum, total energy. We p…
Extracting the Spectrum by Spatial Filtering
Mahmoud Sadek, Hussein Aluie
We show that the spectrum of a flow field can be extracted within a local region by straightforward filtering in physical space. We find that for a flow with a certain level of reg…
