IMPACT OF TEHNICAL SPRAYING FACTORS ON LEAF AREA COVERAGE IN PERMANENT CROPS [PDF]
Poljoprivreda, 2013 Researches are conducted in vineyard and apple orchard with two different types of mist blowers, axial (Hardi Zaturn) and radial (Hardi Arrow). The influence of major technical spraying factors (type of nozzle, working speed and spray volume) were ...

An all-optical event horizon in an optical analogue of a Laval nozzle [PDF]
, 2012 Exploiting the fact that light propagation in defocusing nonlinear media can mimic the transonic flow of an equivalent fluid, we demonstrate experimentally the formation of an all-optical event horizon in a waveguide structure akin to a hydrodynamic Laval nozzle.

A computational fluid dynamic analysis of the effect of weld nozzle geometry changes on shielding gas coverage during gas metal arc welding [PDF]
, 2013 Three geometry changes to the inner bore of a welding nozzle and their effects on weld quality during gas metal arc welding (GMAW) were investigated through the use of computational fluid dynamic (CFD) models and experimental trials. It was shown that an

SINGLE-POINT ENRICHMENT OF AIR CHARGE OF AUTOMOTIVE ENGINEERING DIESEL WITH LIQUID ACTIVATORS [PDF]
Volga Region Farmland, 2019 An effective way to intensify the working process of diesel engines of automotive engineering is to enrich the air charge by supplying a certain dose (10–20%) of a hydrocarbon activator (alcohol, gasoline, kerosene, mineral diesel fuel or mixed vegetable-

Investigation of thrust augmentation and nozzle exit pressure in starting jets from a tube nozzle [PDF]
arXiv, 2020 It has been widely accepted that nozzle exit over-pressure is responsible for thrust augmentation in starting jets over steady jets and a few pulsed jet propulsion systems have been developed based on this finding. However, no other study has been conducted to confirm the nozzle exit over-pressure effect.
