The calculation of these factors is based on methods defined fundamentally for high viscosity Newtonian fluids. A prediction model for head degradation based on the dimensional groups of a centrifugal pump is known for viscous liquids. This model uses experimentally obtained parameters. In this paper, the model’s parameters with glycerol solution were validated by comparing the performance curves estimated with the predicted and measured ones. In addition, a possible way of using the estimation model with power-law fluid was investigated. Based on our experimental results at nominal rotational speed, a form for calculating a virtual shear rate was determined, with the help of which the predicted correction factors and head degradation curves at other rotational speeds showed a good agreement with the measurements. The reported results can be considered as a first step in developing an estimation procedure for head degradation of centrifugal pump’s operation with power-law fluids.","PeriodicalId":101634,"journal":{"name":"Proceedings of the 2nd International Conference on Fluid Flow and Thermal Science (ICFFTS'21)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129960277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of these simulations were performed based on the continuum (conventional or macroscopic) Navier-Stokes equations. In recent years, mesoscopic methods based on the Boltzmann equation, such as the lattice Boltzmann method and gas kinetic schemes, have been developed and applied to these complex flows. In this talk, I will discuss our recent work on extending a specific mesoscopic method known as the discrete unified gas kinetic scheme (DUGKS) for simulations of compressible turbulence and compressible natural convection flows. My talk will cover the underlying theory, code implementation, and simulation results.","PeriodicalId":101634,"journal":{"name":"Proceedings of the 2nd International Conference on Fluid Flow and Thermal Science (ICFFTS'21)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130842782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
