Relevance of turbulence behind the single square grid to turbulence generated by regular- and multiscale-grids
Direct numerical simulations were carried out to study the turbulence generated by a fractal square grid at a Reynolds number of ReL0 = 20000 (based on the inlet velocity Uin and length of theExpand
Development of turbulence behind the single square grid
In this paper, direct numerical simulations are carried out to study single-square grid-generated turbulence at a Reynolds number ReL0 = 20 000 (based on the inlet velocity Uin and the length of gridExpand
Spatial evolution of the helical behavior and the 2/3 power-law in single-square-grid-generated turbulence
Direct numerical simulations are performed to investigate the helical properties of single-square-grid-generated turbulence. The streamwise evolution of the probability density functions of theExpand
Enstrophy production and dissipation in developing grid-generated turbulence
Direct numerical simulations are performed to investigate the spatial evolution of small-scale motions in turbulence behind a single square grid. Some aspects of small-scale motions, which areExpand
On the evolution of the invariants of the velocity gradient tensor in single-square-grid-generated turbulence
Direct numerical simulations were performed to investigate the topological evolution of turbulence generated by a single square grid. Immediately behind the single square grid (i.e., in theExpand
Influence of spheroidal particle shape on particle size characterization by multi-wavelength light extinction method
Abstract In order to improve the applicability, spheroidal particles are substituted for the spherical particles in the traditional modeling of multi-wavelength light extinction method. TheExpand
Analysis of stick-slip reduction for a new torsional vibration tool based on PID control
TLDR
The results show that the new torsional vibration tool can reduce the stick-slip vibration and the two PID control equations can both control the drill bit speed in real time through changing the turntable speed. Expand
Resistance uncertainty and structural reliability of hypar tensioned membrane structures with PVC coated polyesters
Abstract This paper presents the resistance uncertainty and structural reliability of hypar tensioned membrane structures with PVC coated polyesters. First, series of tensile tests are carried out toExpand
Extreme events and non-Kolmogorov $-5/3$ spectra in turbulent flows behind two side-by-side square cylinders
Turbulent flows behind two side-by-side square cylinders with three different gap ratios, namely, $L_{d}/T_{0}=4,$ 6 and 8 ( $L_{d}$ is the separation distance between two cylinders and $T_{0}$ isExpand
Kinetic Tensegrity Grids with 3D Compressed Components
This paper details a series of preliminary explorations into the concept of kinetic tensegrity grids that can respond to stimuli by changing their shape, porosity, and transparency. The researchExpand
