Numerical Simulation Study on Pressure Loss Characteristics of Rotor Multi-Jet Water Meter
Water meters play an important role in water supply,drainage,and trade settlement.And pressure loss is an important technical indicator of water meters.Taking the rotor multi-jet water meter as the research object,the FLUENT solver is used to numerically simulate its internal flow field,explore the relationship between water meter pres-sure loss and flow rate,and analyze the distribution of pressure loss.The research results indicate that the impeller box is the main source of pressure loss,with a pressure loss ratio of up to 67%under Q3 operating conditions.The experiment of measuring pressure loss by replacing different components further verifies this inference,and it is found that increasing the inlet and outlet of the impeller box has a significant effect on reducing the pressure loss of the rotor multi-jet water meter.
