This paper focuses on the delivery flow characteristics of the micro two-dimensional piston pump. A computational fluid dynamics model of the pump is established, and its reliability is verified through experiments. The research results show that the micro two-dimensional piston pump has excellent self-priming ability, and the rated maximum speed can reach 9000 r/min at an inlet pressure of 0.3 MPa. When operating at its rated maximum speed, the delivery flow rate is 0.58 L/min at a load pressure of 8 MPa and 0.44 L/min at 28 MPa, exceeding the delivery flow rate of micro axial piston pumps of the same size by more than 1.7 times. The pump adopts the distribution spindle design that increases flow loss due to internal leakage and flow backward under high load pressure, with these losses accounting for 62 % and 33 % of the total flow loss, respectively.</div></div>","PeriodicalId":50440,"journal":{"name":"Flow Measurement and Instrumentation","volume":"106 ","pages":"Article 102956"},"PeriodicalIF":2.3,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144242509","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although numerous studies have employed the reservoir drawdown method to calibrate large weirs since the 1960s, data on flow measurements during the passage of hydrographs remain scarce. This article investigates the behavior of unsteady flow over rectangular and triangular sharp-crested weirs under various hydrograph shapes with differing intensities of unsteadiness. Two experimental setups were constructed to collect the data and to observe the performance of these weirs. The collected data were then used to evaluate the accuracy of applying steady-flow rating curves for discharge measurements under unsteady flow conditions. A new index, the Relative Loop Width Index (RLWI), is introduced to quantify the effects of unsteadiness on discharge measurements and the associated errors when utilizing conventional steady flow rating curves. The findings indicate that using steady-flow rating curves in unsteady conditions, which are dominant in field conditions, can result in errors in water volume estimation ranging from +10 % to −20 %. Furthermore, steady-flow rating curves applied to flow measurements during hydrograph passage tend to overestimate peak flows and predict earlier occurrence of peak times. Sensitivity analysis reveals that weir geometry and reservoir capacity significantly influence measurement errors.</div></div>","PeriodicalId":50440,"journal":{"name":"Flow Measurement and Instrumentation","volume":"106 ","pages":"Article 102970"},"PeriodicalIF":2.3,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144242511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
