Spacing effect on the vortex-induced vibrations of near-wall flexible cylinders in the tandem arrangement

Spacing effect on the vortex-induced vibrations of near-wall flexible cylinders in the tandem arrangement

Physics of Fluids, Volume 34, Issue 9, September 2022. The vibration responses and flow dynamics in the vortex-induced vibrations of two near-wall flexible cylinders in the tandem arrangement are investigated through three-dimensional direct numerical …

Deformation and seepage properties of raw coal during the simultaneous loading and unloading of axial stress and confining pressure

Deformation and seepage properties of raw coal during the simultaneous loading and unloading of axial stress and confining pressure

Physics of Fluids, Volume 34, Issue 9, September 2022. The mining of coal resources causes the stress on the front and both sides of the working face to be in a complex loading and unloading process, and the gas contained in the coal body migrates, whi…

Low-power, high-performance, and small-footprint, single-pump optical parametric amplifier for photonic integrated circuits

Low-power, high-performance, and small-footprint, single-pump optical parametric amplifier for photonic integrated circuits

Journal of Applied Physics, Volume 132, Issue 12, September 2022. A single-pump optical parametric amplifier (OPA) is modeled using a p-toluene sulfonate (PTS) filled silicon-based slotted photonic crystal waveguide (SPCW). The PTS-SPCW has CMOS-proces…
