远景能源是全球领先的智慧能源技术解决方案提供商。风电场的快速准确评估是公司非常关注的一个方面。西递安科软件技术（上海）有限公司是STAR-CCM+在中国的软件销售与服务商，在风电场评估方面有较多的技术积累。

为了验证STAR-CCM+在风电场评估方面的性能，我们结合贵公司的实际工程，测试了两个案例，并得出了STAR-CCM+在易用性、稳健性及计算精度方面都有比较突出的优势。项目背景CD-adapcoShanghai20142CASE1-ProcessCD-adapcoShanghai20143CASE1-ImportMapCD-adapcoShanghai20144CASE1-IssueswiththeoriginalmapfileObservedunphysicalspikesforfirstimportofthemapfile.Tracedtoerrorsintheinputremovedfromthemapfile.CD-adapcoShanghai20145CASE1-ValidMapFileCD-adapcoShanghai20146CASE1-ExtractComputationDomainCD-adapcoShanghai20147计算域Domain9.5x9.5x10kmhighProcessisachievewithSTAR-CCM+CAD&BooleanOperationsCASE1-MeshGenerationCD-adapcoShanghai20148CourseMeshinFarfieldHexahedraldominantMesh~9MelementsCASE1-MeshGenerationCD-adapcoShanghai20149MajorityofmeshisnearterrainAnisotrophicelementsCASE1-MeshGenerationCD-adapcoShanghai201410ExtrusionLayerGeneratedEvenoncomplexterrain.CASE1-MeshGenerationCD-adapcoShanghai20141150extrusionheight9layers2mfirstcellheightX,Yresolution25mCASE1-PhysicsCD-adapcoShanghai201412ModifiedTurbulenceCoeffsCµC1εC2εDefault0.091.441.92Modified0.031.442.223CASE1-RoughnessVeryhighroughness,couldbeforest?LookinGoogleMapsCD-adapcoShanghai201413CASE1-ActualTerrainCD-adapcoShanghai201414AssumeTrees8mhighApplyCanopyModelMomentumSinkmodelDaCosta,Castro,&Palmer2005CASE1-Roughness&ForestCD-adapcoShanghai201415CASE1-Roughness&ForestCD-adapcoShanghai201416Roughness>0.5isconsideredforestCASE1-BoundaryConditionsCD-adapcoShanghai201417InletboundaryZref=30;uref=6；Zh=1000;Z0=max(interpolatePosotionTable（@（“roughness”,“Rough”),1e-4)CASE1-AutomaticSetupCD-adapcoShanghai201418CASE1-DataExtractionCD-adapcoShanghai201419Foramodernworkstation/cluster.SetupMapImportwithcleanmap<5minutesCleaningthismaptook~40minutes~7MtrianglefacesSetupandvolumemeshingfromfixedmap<25minutes12casesinitialsetupSolve1caseHPC,800iterationscoupledsolver,64cores~2200sCASE1-TimingsCD-adapcoShanghai201420Solve12cases,oneaftertheother12*2200/3600~7.5hourson64coresWedemonstrated,thatthe12directionsweresolvedin24hoursafterwestarted.StartTuesdaymorningEndTuesdayeveningCASE1-Timings(continued)CD-adapcoShanghai201421MostcustomersthatusetheEnviroWizardusetheautomatedapproach.NoGUIWhenthemapfileisgood,theautomaticprocessisrobust.1000sofcaseshavebeencompletedusingthisapproach.JAVAistheautomationlanguageofSTAR-CCM+CASE1-AutomationCD-adapcoShanghai201422MapfileDomainextentsSTAR-CCM+UseGUItodevelopProcessthenAutomateAll12casesrantocompletion.Convergenceofturbulenceatmetmastachievedin<800iterationsForestandsourcesonthecellsnexttoboundary.Robustwithreverseflow.CASE1-RobustnessCD-adapcoShanghai201423CASE1-Robustness-TIConvergenceCD-adapcoShanghai201424000120060030090150CASE1-Robustness-TIConvergenceCD-adapcoShanghai201425180300240210270330
