Get Price1995-2-1 · This paper presents local heat transfer data for a planar, free-surface jet of water impinging normal on a uniformly heated surface. The hydrodynamic conditions of the jet were altered through the use of different nozzle types (parallel-plate and converging) and flow manipulators (wire grid and screens) to investigate the relationship between jet turbulence and local impingement heat transfer.
Get Price2018-7-12 · During the microelement traveled in multi-nozzle NFES process, the effect of adjacent nozzle on electric field can be neglected due to the effect of nozzle is far overweight the neighboring ones in vertical direction. As a result, the microelement travels in vertical direction of multi-nozzle NFES is consistent with condition of dual-nozzle one.

Chen et al. showed by applying mathematical models (the Well–Riley model, competing-risk model and Von Foester equation), that public health interventions (vaccination, insulation, tracing down of the contacts of infected people etc.) are not enough to stop the outbreak of a disease in a modern society. They concluded that more advanced methods need to be applied to help ...
