Impinging jets are widely used for heat and mass transfer because they applicable to any type of body can be easily implemented. They also in various industrial fields design techniques. Previous research investigated e.g. a jet impinging onto flat surface. However, since most the mechanical parts have curvature on their surface, it is necessary study more detailed properties curved surface usi...

in this paper the effects of transmittance, dispersion angle and diffusion length on the quantum efficiency of solar cells (qesc) have been simulated and investigated. optical path technic is used for simulation. the results show that base thickness, diffusion length, dispersion angle, number of optical confinement path and transmission angles have an extremely effects on the qesc. simulation r...

We herein describe a 34-year-old woman with a persistent left superior vena cava (PLSVC) impinging on the posterior wall of the left atrium, subdivided by a membrane at the distal part of the impingement. In this patient, a much dilated coronary sinus due to the PLSVC resulted in a membrane-like structure in the posterior wall of the left atrium with the appearance of the cor triatriatum in tra...

Impinging dilute sodium dodecyl sulfate (SDS) droplets on micropillar-arrayed polydimethylsiloxane surfaces were experimentally investigated. It was found that the behaviors of impinging greatly depend surface roughness and SDS concentration. Similar to pure water droplets, there exists a narrow range dimensionless Weber number, We, for complete rebound impacting droplets. The lower upper limit...

Background. In clinical color Doppler examinations, mitral regurgitant jets are often observed to impinge on the left atrial wall immediately beyond the mitral valve. In accordance with fluid dynamics theory, we hypothesized that a jet impinging on a wall would lose momentum more rapidly, undergo spatial distortion, and thus have a different observed jet area from that of a free jet with an ide...

For high-speed air breathing engines, fuel injection and subsequent mixing with air is paramount for combustion. The high freestream velocity poses a great challenge to efficient mixing both in macroscale and microscale. Utilising cavities downstream of fuel injection locations, as a means to hold the flow and stabilise the combustion, is one mechanism which has attracted much attention, requir...

Organic-based aerosols may play an unexpectedly important role in the atmospheric processing of water vapor. In this paper, we report results of a molecular dynamics (MD) study on the sticking coefficient of water vapor on a coated particle (water droplet coated with fatty acid of radius approximately 4 nm). The sticking coefficient was found to be almost a constant (11-16%) for incident speeds...
