This book focused on the description, explanation,andcommentonthesimulationtoolsandmethodsofsupercriticalCO 2 (sCO ) turbomachinery, which is one of the most important components in sCO 2 2 cycle. The Chinese Government has issued a series of documents to explain China’s controloverthecarbondioxideemissions.PresidentXiJinpingstatedthat“weaimto havecarbondioxideemissionspeakbefore2030andachievecarbonneutralitybefore 2060”, i.e. the “Dual-carbon” goal. To achieve this target, China is expanding the utilizationofrenewableenergyincludingsolarenergyandwindenergy.Meanwhile, Chinaisdevelopinghighefficiencyandflexiblecoalfiredpowerplant,usingsCO 2 cycleinsteadofwidelyusedsupercriticalwater-steamRankinecycle.Forthermal- power conversion, the sCO cycle has the benefit of higher efficiency, compacter 2 size,andfasterresponsetoloadvariations,comparedwithothertechnologies.The accuratedesignofsCO turbineisoneofthechallengesforsCO cycledevelopment. 2 2 ThebookauthoredbyDr.JianhuiQifillsthisgap.Iamsurethatthebookwillprovide valuableguidelineforthedesignandoperationofsCO turbomachinery,andattract 2 widerreadersfromscientists,engineers,andyoungstudentsworkinginthisarea. Dr.JianhuiQiobtainedhisPh.D.degreefromUniversityofQueenslandin2019, and joined Shandong University as an associate professor in 2020. In the winter of 2020, he joined my group as a visiting scholar at North China Electric Power University. From my close contact with him, I found that he is very smart and creative. I am impressed that he has wide knowledge in thermal physics field. He haspublishedabout10high-qualitypapersregardingsCO turbomachinery,andis 2 activeforattendingvariousacademicconferences. Thebooknotonlycontainsthecollectionsofhispreviousworks,butalsoincludes otherpeople’sworkworldwide.Amajorcontentofthisbookreferstothepreliminary ix x ForewordbyJinliangXu design of radial inflow turbine. Especially, he summarized his progress made in the batch design for stator and rotor. Based on his study, the preliminary design tool TOPGEN is improved, adding the capability to design sCO radial turbine. 2 He improved the turbine loss models to increase the prediction accuracy. As an inversedesign,Dr.JianhuiQiovercamethechallengeforstatornozzleguidevanes design,bydesigningthestatorgeometrybasedonrotorinletgeometryandoperation conditions. With these improvements, readers can easily and quickly identify an optimizedturbinedesign.

In summary, Simulation Tools and Methods for Supercritical Carbon Dioxide Radial Inflow Turbine is a valuable book that contains Dr. Jianhui Qi’s original work. I am looking forward to the publication of the book, and I am sure that the book is helpful for the development of sCO power cycle driven by various heat 2 sourcesincludingsolarthermalenergy,chemicalenergyandnuclearenergy. Beijing,China Prof.JinliangXu,Ph.D. March2022 [email protected] Foreword by Kuihua Han Ashissupervisorinthemasterstudy,I’mpleasedtointroducethelatestworkofDr. JianhuiQi,whichisacceptedforpublicationinSpringerNature.Dr.Qireceivedhis Ph.D. degree from the University of Queensland in 2019. Before that, he received his B.Eng. degree and M.Eng. degree from Shandong University. He finalized the researchinthefieldofcleancombustionandbiomassutilizationundermysupervi- sion.SupportedbytheChinaScholarshipCouncil(CSC),hewenttotheUniversity ofQueenslandunderthesupervisionofDr.IngoH.J.JahnandProf.KamelHooman to pursue his Ph.D. degree. After that, he came back to my team as an associate professorinresearch. At the University of Queensland, his research direction shifted from the clean combustion of biomass to the supercritical CO power cycle, especially the core 2 componentofthepowercycle,turbomachinery.DuringhisstudiesinAustralia,he overcamethedifficultiescausedbychangingresearchfields,culturaldifferencesand languages,andcompletedhisdoctoralresearch. Australia is one of the few countries in the world with abundant solar energy resources. His research focuses on providing advanced power cycles for concen- trating solar power to obtain clean energy more efficiently. The supercritical CO 2 powercycleisthemostsuitable.ThemotivationforhisPh.D.projectcamefromthe factthattherearefewsystematicmethodsandtoolsforsimulationandoptimization ofsmallscalesupercriticalCO radialinflowturbines. 2 This book is a derivative of Dr. Qi’s doctoral thesis. His work deals with the high-fidelitysimulationtoolsfornext-generationsupercriticalcarbondioxideradial inflow turbines. A comprehensive work-flow for supercritical CO radial inflow 2 turbine design and optimization was developed. From preliminary design, design space analysis, CFD study with non-ideal computational fluid mechanics effect to bladegeometryoptimization,everysteparewell-consideredandorganized.Through hiswork,thefeasibilityofsmallscaleradialinflowturbineisvalidatedwithupdating mean-linedesignmethodology,thegapbetweenmean-linecodeandtimeconsuming fullCFDsimulationsisbridgedbydevelopingmoreefficienttools(Riemannsolver within OpenFOAM framework, optimization tool based on modularized method- ology and fast geometry generator), and more insights are revealed through the xi xii ForewordbyKuihuaHan simulationofsCO radialinflowturbines.Duringthewritingprocessofthisbook, 2 Dr.Qihasdonealotofwork:hehascreatedalotofcodes,drawnmanybeautiful graphs,andappliedforsomepatentsandsoftwarecopyrights.Mostimportantly,his researchisentirelybasedonopen-sourcecodeandsoftware,suchasOpenFOAM, Eilmer3,andPython.Hisworkopensupaparallelroutetotheuseofcommercial softwarewhichisexpensiveandhasnotyetreachedthescientificfrontiers.
