Open-jet facility for bio-inspired micro-air-vehicle flight experiment at low speed and high turbulence intensity

Advances in Aerodynamics
Bio-inspired micro-air-vehicles (MAVs) usually operate in the atmospheric boundary layer at a low Reynolds number and complex wind conditions including large-scale turbulence, strong shear, and gusts.

Lamb-Wave-Based Multistage Damage Detection Method Using an Active PZT Sensor Network for Large Structures

Sensors, 2019
A multistage damage detection method is introduced in this work that uses piezoelectric lead zirconate titanate (PZT) transducers to excite/sense the Lamb wave signals.

A Review on Microreactor Design for Effective Fischer–Tropsch Process Intensification

Advanced Materials Technologies, EarlyView.
Design strategies for effective Fischer–Tropsch process intensification are summarized based on experimental and simulation experiences. Recommendations for catalyst loading of packed‐bed and wash‐coated microchannel, microtube, micromonolith, and microstructured reactors are discussed.

Host Tuned Luminescence Lifetime Thermometers for Imaging Boiling Thermal Dynamics Through Bubbles

Advanced Optical Materials, EarlyView.
The bismuth to vanadate distance is adjusted in solid solutions of ytrrium and scandium orthovanadate to design a lifetime‐based luminescence thermometer with optimal temperature resolution at 100 °C. It is applied on the surface of a boiling channel to observe the thermal signatures of bubble growth and liquid film dry‐out.

Research on an efficient prediction for deformations of thread connections based on deep transfer learning

Scientific Reports
Threaded connections are essential components in mechanical assemblies, subjected to complex deformations under various loading conditions (e.g., tension, torque, bending, and shear), influenced by bolt geometry and material properties.

A minimum-domain impulse theory for unsteady aerodynamic force with discrete wake

Theoretical and Applied Mechanics Letters, 2017
We extend the impulse theory for unsteady aerodynamics, from its classic global form to finite-domain formulation, then to a minimum-domain version for discrete wake. Each extension has been confirmed numerically. The minimum-domain theory indicates that

ON THE DECAY OF TURBULENCE

Acta Physica Sinica, 1953
This paper consists of two parts. The first part gives a description of the motion of large eddies in a turbulent flow. The non-stationary character of the large eddies is emphasized. Up to present, there appears to be some confusion regarding the law of turbulence decay, especially the variation of the microscale with time. This paper introduces a new
