Temporal large-scale intermittency and its impact on the statistics of turbulence

L Bentkamp, M Wilczek - arXiv preprint arXiv:2312.08281, 2023 - arxiv.org
Turbulent flows in three dimensions are characterized by the transport of energy from large
to small scales through the energy cascade. Since the small scales are the result of the …

Mixing in modulated turbulence. analytical results

WJT Bos, R Rubinstein - Computers & Fluids, 2017 - Elsevier
Recent numerical results show that if a scalar is mixed by periodically forced turbulence, the
average mixing rate is directly affected for forcing frequencies small compared to the integral …
