Accounting for convective effects in zero-Mach-number thermoacoustic models [PDF]
, 2014 This paper presents a methodology to account for some mean-flow effects on thermo-acoustic instabilities when using the zero-Mach-number assumption. It is shown that when a computational domain is represented under the M=0 assumption, a nonzero-Mach ...

Bifurcating Mach Shock Reflections with Application to Detonation Structure [PDF]
, 2011 Numerical simulations of Mach shock reflections have shown that the Mach stem can bifurcate as a result of the slip line jetting forward. Numerical simulations were conducted in this study which determined that these bifurcations occur when the Mach ...

Plasmonic Mach-Zehnder Interferometers Based on Air-Gap Couplers
IEEE Photonics Journal, 2023 Mach-Zehnder interferometers (MZIs) are vital in optical biosensor applications and high-density integrated photonic circuits. In this research work, we theoretically investigate the design steps of MZIs, consisting of 3-dB plasmonic splitters sandwiched

ELECTROPHORESIS, EarlyView.Silicon photonic biosensors enable label‐free, highly sensitive detection but struggle with living bacteria due to inefficient cell binding on nanoscale surfaces. We integrate a microring resonator with a dielectrophoretic electrode, actively concentrating Legionella cells near the sensor using alternating electric fields.

High temperature effects in moving shock reflection with protruding Mach stem
Theoretical and Applied Mechanics Letters, 2016 The influence of high temperature effects on the protrusion of Mach stem in strong shock reflection over a wedge was numerically investigated. A two-dimensional inviscid solver applies finite volume method and unstructured quadrilateral grids were ...

Refraction of Oblique Shock Wave on a Tangential Discontinuity
Fluids, 2021 The refraction of an oblique shock wave on a tangential discontinuity dividing two gas flows with different properties is considered. It is shown that its partial reflection occurs with the exception of the geometrical diffraction of an oblique shock ...
