Electrical Conductivities of Conductors, Semiconductors, and Their Mixtures at Elevated Temperatures
Advanced Engineering Materials, EarlyView.This article presents a comprehensive review of temperature‐dependent electrical conductivity data for multiple material classes at elevated temperatures, highlighting a persistent conductivity gap between metals and semiconductors in the range of 102$\left(10\right)^{2}$– 107$\left(10\right)^{7}$ S/m. Metal–ceramic irregular metamaterials are proposed

Scalar Transport Characteristics Near the Turbulent/Non-Turbulent Interface in a Reactive Jet Flow
气体物理Turbulent/non-turbulent interface (T/NTI) layer separates the turbulent and non-turbulent regions. The study of T/NTI is helpful to deepen the understanding of mass transfer between turbulent and non-turbulent regions.

Particles turbulence interactions in boundary layers [PDF]
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2005 AbstractTurbulent dispersed flows in boundary layers are crucial in a number of industrial and environmental applications. In most applications, the key information is space distribution of particles which is known to be strongly non‐homogeneous. Specifically, inertial particles distribute preferentially avoiding strong vortical regions and segregating
