Abstract Sprays are of great importance for many applications, with drop size being a crucial parameter. Especially in agriculture simple flat fan spray nozzles often supplemented by Venturi component to achieve larger sizes and hence, prevent unwanted drift the smallest droplets. The general believe is that these drops usually attributed fact liquid sheet produced nozzle breaks up more easily ...

BACKGROUND The effect of oxygen therapy in acute ischemic stroke remains undetermined. OBJECTIVE To investigate the feasibility of eubaric hyperoxia therapy by Venturi mask (VM) in a group of patients who experienced a severe acute ischemic stroke. DESIGN Patients experiencing a first-ever large middle cerebral artery infarction were recruited within 48 hours after stroke. Patients were sub...

Sediment abrasion may cause the removal of material and efficiency loss to hydraulic machinery (hydro-turbine, pump, etc.), which worsen internal flow endanger safe operation machines. As is caused by impact sediment on solid surface, movement particles determines wear intensity. To understand mechanism machinery, motion characteristics asymmetric solid–liquid two-phase in a sediment-laden arou...

A multiphase flowmeter (MPFM) is used in the upstream oil and gas industry for continuous, in-line, real-time, oil-gas-water flow measurement without fluid separation. An MPFM typically consists of phase-fraction (holdup) velocity (or rate) measurements. It desirable to have homogeneous at location so that representative. horizontal blind-tee pipe-section often installed homogenize downstream v...
