Bimodal Mechanoluminescence Enables Multicolor Luminescent Tailing for Ultra‐Accurate Loading Speed Visualization and Detection

Advanced Science, EarlyView.
MgF2 exhibits a speed‐dependent mechanoluminescence (ML) color distribution arising from distinct ML lifetimes, showing blue emission under slow sliding and multicolor emission under fast sliding. A promising method for evaluating ML lifetime is proposed based on the trailing effect. By synergistically integrating instantaneous and persistent ML with a

Simulated conformal dome wind tunnel experiments

2013 IEEE Third International Conference on Information Science and Technology (ICIST), 2013
In this paper, a kind of wind tunnel experiment will be discussed. This wind tunnel experiment is used for conformal dome design. Wind tunnel experiments are done with different speed and attack angles. The results together with the simulation results got before will be used for coupling simulation FEA software.

Wind Tunnel Experiments

1998
The intention of wind-tunnel experiments (or in general physical modelling, including water-tank experiments) is to reproduce the characteristics of the atmospheric boundary layer on a small geometric scale, typically between 1/100th and 1/1000th of the real world. In the previous chapters, numerical models were grouped into different classes depending

A Numerical Wind Tunnel Experiment

2002
In this paper we study the possibility of generating homogeneous, isotropic turbulence by putting a grid in a channel flow. Several statistics are studied to assess the quality of the turbulence. Also, the effect of the inclusion of a contraction on the isotropy of the turbulence is considered.
