并联管在热能动力、石油化工、太阳能等工程中有着广泛的应用,对并联管内流体流动的实验研究是并联管研究中的主要任务之一。 本文描述了并联管内可视化流动的实验方法,它区别于测压计—流量计的外部测
Parallel pipe has a wide range of applications in thermal power, petrochemical, solar energy and other projects. Experimental study of fluid flow in a parallel pipe is one of the main tasks in the study of parallel pipe. This article describes an experimental method of visualizing the flow in a parallel pipe that is distinct from the external measurement of the manometer - the flowmeter
