Experimental study of multi-path ultrasonic flowmeters measurement accuracy in complex flow fields was carried out in the water flowrate standard facility of National Water Large Flowrate Measurement Station. Several muti-path ultrasonic flowmeters with different path arrangement were studied. The flow disturbances were created by bend, tapered pipe, diverging pipe and butterfly valve. By study...

This paper investigates the self-cleansing performance of an airlift pump with a U-bend. For this purpose, experimental setup is used to assess effect air flow on pump's ability lift water and remove particles under different submergence ratios particle concentrations. In addition, simple yet accurate fluid mechanical model interpret experiments individual predict critical velocity required for...

In the process of research and development of tube bending forming technology, the way of improving the forming quality and establishing the optimization of forming process parameters has become an important problem that should be solved quickly. This text simulated the process of bend forming with the way of finite element, combined with the effects of geometric and physical parameters on the ...

Due to the periodic movement of the piston in the reciprocating pump, the fluid will cause 8 pressure pulsation, and the vibration of the pipeline will lead to instrument distortion, pipe failure 9 and equipment damage. Therefore, it is necessary to study the vibration phenomena of the 10 reciprocating pump pipeline based on the pressure pulsation theory. This paper starts from the 11 reciproca...

Laminar fluid-particle flows in bend geometries are present many industrial, pharmaceutical, and biomedical applications. Particle deposition has been studied extensively; however, little attention paid to the effect of particle sedimentation on position different pipe geometry combinations. This study presented a comprehensive analysis effects flow behaviour 90{\deg} circular bends micron part...
