Research on Optimization of Flow Field and Combustion Performance in Boilers With Combined Near‐Wall Air Supply Systems

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT In the pulverized coal boiler industry, reducing NOx emissions has become a critical objective. Although low‐NOx combustion technologies are effective, they may lead to localized high‐temperature corrosion. To address this issue, near‐wall air supply technology has been introduced, which involves injecting an appropriate amount of air near the

Turbulence in Core-collapse Supernovae

The Astrophysical Journal
It is understood in a general sense that turbulent fluid motion below the shock front in a core-collapse supernova stiffens the effective equation of state of the fluid and aids in the revival of the explosion.

Dissipation Scaling with a Variable C_ϵ Coefficient in the Stable Atmospheric Boundary Layer

Atmosphere
This work concerns the Taylor formula for the turbulence kinetic energy dissipation rate in the stable atmospheric boundary layer. The formula relates the turbulence kinetic energy dissipation rate to statistics at large scales, namely, the turbulence ...

Limitations of Hall MHD as a model for turbulence in weakly collisional plasmas [PDF]

Nonlinear Processes in Geophysics, 2009
The limitations of Hall MHD as a model for turbulence in weakly collisional plasmas are explored using quantitative comparisons to Vlasov-Maxwell kinetic theory over a wide range of parameter space. The validity of Hall MHD in the cold ion limit is shown,

Energy transfer, pressure tensor and heating of kinetic plasma

, 2017
Kinetic plasma turbulence cascade spans multiple scales ranging from macroscopic fluid flow to sub-electron scales. Mechanisms that dissipate large scale energy, terminate the inertial range cascade and convert kinetic energy into heat are hotly debated.

Migration and Dispersion Evolution of Exhaled Aerosol in a Ward Under Different Ventilation Modes

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Wards with special functions and closure will have a higher risk of viral transmission as aerosols are an important mode of transmission for the SARS‐CoV‐2 virus. In this study, an experimental platform was built to establish the relevant parameters of the aerosol model and the aerosol propagation model according to the experimental results ...

Solar Cycle Dependence of the Turbulence Cascade Rate at 1 au

The Astrophysical Journal
We study the solar cycle dependence of various turbulence cascade rates based on the methodology developed by Adhikari et al. that utilizes Kolmogorov phenomenology.

Role of reconnection in inertial kinetic-Alfven turbulence

, 2019
In a weakly collisional, low-electron-beta plasma, large-scale Alfv\'en turbulence transforms into inertial kinetic-Alfv\'en turbulence at scales smaller than the ion microscale (gyroscale or inertial scale).
