Turbulent diffusion of chemically reacting gaseous admixtures [PDF]

Physical Review E, Volume 90, Issue 5, id.053001 (2014), 2014
We study turbulent diffusion of chemically reacting gaseous admixtures in a developed turbulence. In our previous study [Phys. Rev. Lett. {\bf 80}, 69 (1998)] using a path-integral approach for a delta-correlated in time random velocity field, we demonstrated a strong modification of turbulent transport in fluid flows with chemical reactions or phase ...

A Hierarchy of Turbulence Closure Models for Planetary Boundary Layers.

, 1974
Turbulence models centered on hypotheses by Rotta and Kolmogoroff are complex. In the present paper we consider systematic simplifications based on the observation that parameters governing the degree of anisotropy are small.

MHD turbulence [PDF]

Living Reviews in Computational Astrophysics, 2019
AbstractWe review the current status of research in MHD turbulence theory and numerical experiments and their applications to astrophysics and solar science. We introduce general tools for studying turbulence, basic turbulence models, MHD equations and their wave modes. Subsequently, we cover the theories and numerics of Alfvénic turbulence, imbalanced

Biohybrid Vascular Graft Made of Textile‐Reinforced Elastin‐Like Recombinamers and Its Preservation via Drying Processes

Advanced Healthcare Materials, EarlyView.
Clinical translation of biohybrid medical implants requires the previous implementation of drying schemes that can facilitate their sterilization and storage. This study addresses that critical aspect and elucidates the impact of drying on biohybrid vascular grafts, highlighting the need for implant‐specific drying strategies to ensure safety ...

Influence of Flow-induced Vibration of a D-VAWT With and Without Leading-edge Rod at Various Pitch Angles [PDF]

Journal of Applied Fluid Mechanics
Under specific incoming wind speeds, Darrieus- Vertical Axis Wind Turbines (D-VAWT) have been found to display significant amplitude vibrations. Previous studies mainly examined the D-VAWT's aerodynamics, ignoring flow-induced vibration (FIV).

Properties and selected implications of magnetic turbulence for interstellar medium, Local Bubble and solar wind [PDF]

, 2008
Astrophysical fluids, including interstellar and interplanetary medium, are magnetized and turbulent. Their appearance, evolution, and overall properties are determined by the magnetic turbulence that stirs it. We argue that examining magnetic turbulence at a fundamental level is vital to understanding many processes.

Micro‐ and Nano‐Bots for Infection Control

Advanced Materials, EarlyView.
This review presents a strategic vision for integrating micro‐ and nanobots in the pipeline for infection diagnosis, prevention, and treatment. To develop these robots as a practical solution for infection management, their design principles are clarified based on their propulsion mechanisms and then categorized infection management domains based on ...

Strong Universality in Forced and Decaying Turbulence

, 2003
The weak version of universality in turbulence refers to the independence of the scaling exponents of the $n$th order strcuture functions from the statistics of the forcing.

Field Theory and the Phenomenon of Turbulence [PDF]

arXiv, 1995
We study the phenomenon of turbulence from the point of view of statistical physics. We discuss what makes the turbulent states different from the thermodynamic equilibrium and give the turbulent analog of the partition function. Then, using the soluble theory of turbulence of waves as an example, we construct the turbulent action and show how one can ...
