Interfacial dynamics and energy cascade in immiscible Rayleigh-Taylor turbulence
Dongxiao Zhao, Xiaoxue Huang, Gaojin Li
We investigate interfacial dynamics and multiscale energy transfer in immiscible Rayleigh-Taylor turbulence using numerical simulations with varying surface tension coefficients $σ…
Emergence of a Flow-Assisted Casting Strategy for Olfactory Navigation via Memory-Augmented Reinforcement Learning
Changxu Zhao, Dongxiao Zhao, Xin Bian +1
In dynamic flow fields, various animals exhibit remarkable odor search capabilities despite relying on stochastic detections. Interestingly, there exists an optimal time window for…
Effects of External Magnetic Fields on the Multi-mode Rayleigh-Taylor Instability
Xin Bian, Riccardo Betti, Dongxiao Zhao +1
The magneto-Rayleigh-Taylor instability (mRTI) is a key process in inertial confinement fusion and is thought to be widespread in the interstellar medium, where it can concentrate…
Calculating Spectra by Sequential High-Pass Filtering
Dongxiao Zhao, Hussein Aluie
We expand on the method of sequential filtering for calculating spectra of inhomogeneous fields. Sadek & Aluie [Phys. Rev. Fluids, 3, 124610 (2018)] showed that the kernel has to h…
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…
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…
