With the prevalence of COVID-19, phenomenon viruses spreading through aerosols has become a focus attention. Diners in university dining halls have high risk exposure to respiratory droplets from others without protection face masks, which greatly increases COVID-19 transmission. Therefore, transmission mechanism extremely crowded environments should be investigated. In this study, numerical simulation coughing at tables under two conditions was performed, namely presence and absence...
Phase sensitive optical time domain reflectometry (Φ-OTDR) has been widely used in the precise acquisition of vibration signal along sensing fiber, and attracted more interest. However, polarization fading coherent usually lead to phase hopping recovered signal, thus it is difficult realize continuous measurement vibration, especially low frequency vibration. The diversity multi-frequency detection schemes which are solve above problems need additional hardware, increasing cost complexity...
Combustion test diagnosis has always been one of the most important technologies for development aerospace engineering. The traditional methods measurement have unable to meet requirements accurate capture flow field in process aeroengine combustor. Therefore, high-precision and diagnostic techniques needs combustor design is imperative. Laser diagnostics developed quickly past several years. They are used measure parameters combustion such as velocity, temperature, components concentration...
We theoretically propose a narrowband perfect absorber metasurface (PAMS) based on surface phonon polaritons in the terahertz range. The PAMS has unit cell consisting of silver biarc top, thin polar-dielectric middle and layer at bottom. are excited interface between polar dielectric, enhance absorption PAMS. peak is 36.813 μm full width half maximum (FWHM) nearly 36 nm, independent polarization incidence angle. electric fields located split quality factor Q 1150. FWHM decreases with...
To analyze the carrier lifetime of Si, a 0.4 mm thickness high-resistivity silicon had been investigated by optical-pump-terahertz-probe (OPTP) system. The terahertz time domain curve and frequency spectrum (bandwidth > 6THz) Si are achieved spectroscopy mode, its characteristic parameters, including refractive index absorption coefficient, were obtained. And was measured OPTP result is about 905 ps.
An external axisymmetric model featuring a cavity flame-holder fuelled by hydrogen was adopted for the study of supersonic combustion in Mach 2 flows. The self-sustained flames ignited spark gap igniter were detected using two optical techniques: an intensified camera attachment coupled with high speed narrow-band-pass filter centred at 310 nm detection OH* chemiluminescence; and high-speed schlieren imaging flow visualization. ignition identified on images which also enabled visualisation...
