【优秀word硕士论文】基于多传感器融合的两相流参数测量方法

基于多传感器融合的两相流参数测量方法MULTISENSORFUSIONBASEDMEASUREMENTONTWOPHASEFLOWPARAMETERS摘要两相流是自然界与工业过程中十分常见的流动形态，由于流态的复杂性，对其过程参数的准确测量一直是科学研究与工业过程应用中亟待解决的重要课题。多传感器融合技术利用不同时间与空间的多传感器数据资源，通过对各局部测量信息的综合，消除多传感器信息之间可能存在的冗余和矛盾，并加以互补，降低其不确定性，实现比单一信息源对被测过程更完全、准确、可靠的测量和描述。本论文从两相流参数测量方法与流动机理出发，利用数值仿真技术，在研究V型内锥流量计与基于电学敏感原理的传感器用于两相流参数测量方法的基础上，建立各传感器两相流测量模型；结合数据级与特征级信息融合方法实现两相流流型的准确识别，以及质量流量、流速、分相含率和分相表观流速的测量。本研究主要完成的工作1从两相流参数测量方法与流动机理出发，开展水平管道油水与气水两相流的三维CFD（COMPUTATIONALFLUIDDYNAMICS）非稳态仿真，分析两相流典型流动状态下，V型内锥流量计的测量特性，以及流动参数在预设测量截面处的变化；在此基础上设计并实现了基于电学敏感原理传感器的两相流流动参数测量系统。2在对已有两相流差压测量关系式分析的基础上，推导出油水两相流粘度对差压测量关系式的影响，提出一种考虑油水粘度影响的油水两相流质量流量关系式；实现了利用环形电导式传感器测量气水两相流的滑动比，并提出一种适用于研究工作实验范围的气水两相流质量流量测量关系式。3结合两相流流动特性分析，提出一种能够在两相流流动特征信号中动态寻找信号段适用于互相关计算的方法，并建立了基于电学敏感原理的两相流混合流速测量以及分相含率的预测模型，实现了两相流双参数的同时测量。4在各传感器测量模型与方法研究的基础上，实现了基于双截面电阻层析成像系统截面电极阵列间的数据级融合、特征级串行融合与并行融合；研究了基于V型内锥流量计与电阻层析成像系统测量数据特征级融合的水平管气水两相流流型识别方法；实现了基于V型内锥流量计与电学敏感原理传感器融合的两相流流速、相含率与滑动比的预测，以及两相流流量和各分相表观流速的准确测量。关键词油水两相流；气水两相流；V型内锥流量计；过程层析成像；环形电导式传感器；传感器融合；流型识别；过程参数检测ABSTRACTTWOPHASEFLOWISCOMMONLYENCOUNTEREDANDOFPARAMOUNTSIGINIFICANCEINBOTHNATURALANDINDUSTRIALPROCESSES,ANDYETITSRHEOLOGICALCOMPLEXITYMAKESTHEACCURATEMEASUREMENTONITSPROCESSPARAMETERSDIFFICULTTOACHIEVEANDHENCEPRESENTSANURGENTISSUETOSCIENTIFICRESEARCHERSANDINDUSTRIALENGINEERSMULTISENSORFUSIONTECHNIQUESCOMBINEDATAANDRELATEDINFORMATIONFROMPATIALLYANDTEMPORALLYDISTRIBUTEDSENSORSTOACHIEVEMORECOMPLETE,SPECIFICANDRELIABLEINFERENCESTHANCOULDBEACHIEVEDBYUSINGASINGLE,INDEPENDENTSENSORTHEINTEGRATIONORFUSIONOFDATAFROMEACHLOCALSENSORELIMINATESPOSSIBLEREDUNDANCYANDCONTRADICTIONSANDCONSEQUENTLYIMPROVESACCURACYANDUNCERTAINTYOFTHEMEASUREMENTINLIGHTOFTHEPARAMETRICMEASURINGTECHNIQUESANDFLOWMECHANISMOFTWOPHASEFLOW,THEMEASURINGMODELSOFVCONEMETERSANDELECTRICALLYSENSITIVESENSORSAREESTABLISHEDTHROUGHNUMERICALSIMULATIONSTHEPROCESSPARAMETERSOFTWOPHASEFLOW,SUCHASFLOWREGIME,MASSFLOWRATE,ANDFLOWVELOCITYASWELLASTHEPHASECONSENTRATIONAREJOINTLYDETERMINEDWITHDATAFUSIONANDFEATUREFUSIONMETHODSTHEMAINWORKSACCOMPLISHEDAREASFOLLOW1BASEDONTHEPARAMETRICMEASURINGTECHNIQUESANDFLOWMECHANISMOFTWOPHASEFLOW,TYPICALFLOWCONDITIONSOFOILWATERANDGASWATERTWOPHASEFLOWWERESTUDIEDTHROUGHCFDUNSTABLESIMULATIONSONSIMULATIONBASIS,THEMEASURINGPERFORMANCEOFAVCONEMETER,ASWELLASTHECHANGEOFTWOPHASEFLOWPARAMETERSATEACHMEASURINGSECTIONAREINVESTIGATED,ANDTHEMEASURINGSYSTEMSOFELECTRICALLYSENSITIVESENSORSWEREBUILT2THEINFLUENCEOFVISCOSITYOFOILWATERTWOPHASEFLOWUPONTHEDIFFERENTIALPRESSUREMODELISDERIVEDINVIEWOFTHEEXISTINGMODELSFORTWOPHASEFLOW,FROMWHICHACORRELATIONOFMEASURINGTHEMASSFLOWRATEOFOILWATERTWOPHASEFLOWISPRESENTEDINCONSIDERATIONOFTHEVISCOSITYCHARACTERBESIDES,ASLIPRATIOBASEDMEASURINGCORRELATIONFORGASWATERTWOPHASEFLOWMASSFLOWRATEMEASUREMENTISPRESENTEDBYINTRODUCINGTHESLIPRATIOWITHCONDUCTIVITYRINGS3WITHTHEANALYSISONFLOWINGPROPERTIESOFTWOPHASEFLUIDS,AMETHODOFDYNAMNICALLYSEEKINGSUITABLESIGNALSEGMENTFORCROSSCRRELATINGMEASUREDSIGNALSFROMTWOPHASEFLOWISPROPOSED,INADDITIONTHEPREDICTIONMODELSOFMIXTUREVELOCITYANDPHASECONCENTRATIONBYUSINGELECTRICALLYSENSITIVESENSORSWEREESTABLISHEDTOACHIEVETHESIMULTANEOUSMEASUREMENTONTHESETWOPARAMETERS4BASEDONTHEINDEPENDENTMEASUREINGMODELANDMETHODOLOGYOFABOVEMEASURINGSYSTEMS,THEINFORMATIONFROMEACHSENSINGPLANEOFADUALPLANEERTSYSTEMISFUSEDATDATALEVELANDFEATURELEVELRESPECTIVELY,MOREOVER,THEMEASUREMENTDATAFROMAVCONEMETERANDANERTSYSTEMISALSOFUSEDATFEATURELEVELANDTHEPERFORMANCEOFEACHFUSIONMETHODISANALYIZEDANDDISCUSSEDWITHTHEFLOWREGIMEIDENTIFICATIONONGASWATERTWOPHASEFLOWINAHORIZONTALPIPEATLAST,THEFLOWVELOCITY,PHASECONCENTRATIONANDSLIPRATIOASWELLASTHEFLOWRATEANDSUPERFICIALVELOCITYOFEACHPHASEAREMEASUREDINACCEPTABLEACCURACYBYFUSINGTHEINFORMATIONFROMAVCONEMETERANDTHEELECTRICALLYSENSITIVESENSORSKEYWORDSOILWATERTWOPHASEFLOWGASWATERTWOPHASEFLOWVCONEMETER,PROCESSTOMOGRAPHYCONDUCTIVITYRINGMULTISENSORFUSIONFLOWREGIMEIDENFICATIONPROCESSPARAMETRICMEASUREMENT目录摘要IABSTRACTIII目录V第一章绪论111多相流及流动参数1111多相流流型2112两相流动基本参数512课题研究背景与现状813论文创新点与主要工作9131论文创新点10132论文组织结构11第二章文献综述1321多相流测量方法综述13211多相流流型识别13212流量测量14213相含率测量17214多相流量计19215发展趋势2222过程层析成像方法综述22221过程层析成像敏感场特性及分类23222过程层析成像系统的构成26223过程层析成像技术在多相流测量中的应用27224过程层析成像技术应用的发展趋势3023多传感器融合30231多传感器32232多传感器融合分类与结构33233融合系统组成3424小结34第三章CFD动态仿真3531仿真设置35311仿真几何模型与网格35312流体特性设置37313多相流模型37314湍流模型38315边界条件与初始化39316求解控制3932仿真结果及分析40321油水两相流仿真结果41322气水两相流仿真结果4633小结49第四章测量系统与实验条件5141电阻层析成像系统5142环形电导式传感器阵列54421电导率变化对测量值影响56422电导环静态标定5643V型内锥流量计理论与标定58431V内锥测量理论模型58432V内锥流出系数标定5944两相流实验装置及实验条件60第五章基于V型内锥流量计的两相流流量测量6351两相流差压测量模型63511均相流模型63512分相流模型63513MURDOCK关系式66514CHISHOLM关系式66515SMITH引用频次5次，他引4次）2DONGFENG,TANCHAO,LIUJUNWEN,XUYANBINANDWANGHUAXIANG,DEVELOPMENTOFSINGLEDRIVEELECTRODEELECTRICALRESISTANCETOMOGRAPHYSYSTEM,IEEETRANSACTIONSONINSTRUMENTATIONANDMEASUREMENT,2006,VOL55,NO4,PP12081214（SCI065UI,EI20063110039449,影响因子0832引用频次2次）3谭超，董峰，王斌斌，多截面电阻层析成像系统并行数据采集的设计，第26届中国控制会议，张家界，湖南，中国，2007072631，VOL5，PP391395EI20080211015319,ISTPBGW824TANCHAOANDDONGFENG,TWOPHASEFLOWREGIMERECOGNITIONINHORIZONTALPIPEBASEDONPOSITIONALINFORMATIONOFMEASUREDDATAOFERT,IEEEINSTRUMENTATIO
