Venturi injector is widely used in fertigation system due to its obvious advantages such as cheap and robust system without mobile pieces, simple structure, convenient to operation, stable performance, needless of external energy for operation etc. At present, the hydraulic parameters such as suction capacity (injection rate) for the most of the Venturi injectors produced domestically are not v...

Hydrogen sulfide is frequently met in natural waters, like mineral springs, but mostly it found marine water with low renewal rate. The Black Sea has extremely high hydrogen content. It can be utilized different ways, the most promising one direct conversion into electricity. This result attained by a sulfide-driven fuel cell (SDFC), converting to sulfate thus releasing electric energy up 24 GJ...

The Venturi meter is a straightforward pipeline device used for the metering of gas and liquids. This article presents a brief summary of the creation and characterisation of the modern Venturi meter, including the historic development of public domain algorithms to derive two phase (gas and liquid) flow rates from differential pressure measurements. The use of Venturi meters in multiphase oil ...

Microbubble generators are in wide demand industry following the discovery of a number new functions microbubble mixtures. This paper deals with Venturi tube generator which air bubbles at inlet fragmented diverging part tube. In contrast past studies, we here regulated flow subsonic so that fragmentation occurred without help pressure shock waves. Counting microbubbles image processing, found ...
