The21stAustralasianFluidMechanicsConferencewasheldfromDecember10thto13th,2018at theAdelaide ConventionCentre.Over the four days therewere 47 sessions covering 30distincttopics,attendedbyatotalof356delegatesfrom24countries.Thedelegatesincluded28 industry personnel, 165 academics and 163 students. Overall therewere 390 abstractsreceivedbytheconferenceorganisers,leadingto7keynotepresentationsand295standardpresentations,158ofwhichweredeliveredbystudents.Of these,approximately45paperswereidentifiedfora(future)specialeditionoftheInternationalJournalofHeatandFluidFlow.TheBatchelorLecturewasdeliveredbyJohnEatonofStanfordUniversity,whichwasfollowedby six brilliant Keynote lectures by leading fluid mechanics researchers, including EllenLongmire(UniversityofMinnesota),BeverleyMcKeon(Caltech),AlfredoSoldati (TUWien),Jens Norkeer Sorensen (Danish Technical University), Julio Soria (Monash University), andYvonneStokes(UniversityofAdelaide).

Under thedirectionof theAFMSRegionalBranchessubcommittee,proposalsweresought in2018fortheformationofLocalChaptersoftheAFMS.ThepurposeoftheLocalChaptersistopromote fluidmechanics at a regional level, increase communication between the local andnationalregionalmembersandtheAFMStherebyenablingengagementandresponsetolocalgovernment and industry needs in fluid mechanics, and to increase collaboration in fluidmechanicsacrossregionalandnationallevels.

Early in 2019 the AFMS council approved proposals from the ACT and WA to form LocalChapters.BothChaptershavesincecommencedpreparationsfortheirinauguralevents,tobeheldlaterthisyear.TheseincludethefirstAFMSsummerschool(seenoteabove)tobeheldinCanberra and a fluid mechanics showcase to be held in conjunction with the Institute ofEngineersinPerth.
