1涡轮叶栅前缘上游端壁气膜冷却的流场实验研究显示文摘对前缘上游端壁有单排和双排孔冷却的大尺寸低速涡轮导向叶栅进行了气动测量、热示踪和端壁流场显示 ,在吹风比 1~ 3范围获得了叶栅内的详细流场、冷气的空间分布和端壁上的流动图案。结合先前测得的没有冷却时的流场数据 ,这些结果表明端壁气膜冷却对叶栅流场结构有重大影响 ,吹风比是主宰射流与二次流间相互作用的主要因素 ,双排孔喷射使冷气比单排孔喷射更贴近端壁。低吹风比喷射冷气不能到达压力面并被二次流逐渐卷离端壁 ;中吹风比喷射有效的抑制了二次流的形成 ,并使端壁流线偏向于无粘流流线 ,冷气很均匀的覆盖在端壁上 ;高吹风比喷射可将冷气抛射到压力面上 ,双排孔情况下甚至使二次流反向 。刘高文 刘松龄 许都纯 Lapw orth B L Forest A E 2001航空动力学报2001,16,2:20
2涡轮叶栅前缘上游端壁气膜冷却的传热实验研究显示文摘对前缘上游有单排和双排孔冷却的涡轮导向叶栅端壁进行了详细的传热实验 ,在吹风比 1 ,2 ,3下获得了当地气膜冷却效率和换热系数 ,结合流场测量结果分析了端壁冷却和换热规律。结果表明端壁气膜冷却在很大程度上受二次流的影响 ,冷却效果主要由吹风比决定 ,低吹风比喷射时 ,压力面附近的一个三角形区域没有冷气的覆盖 ,中、高吹风比喷射可以大幅度提高平均冷却效率并使冷气很均匀的覆盖在端壁上 ,双排孔喷射比单排孔喷射平均效率提高 1倍左右。结果还表明尽管冷气喷射使端壁换热系数随吹风比的增大而显著增大 ,气膜冷却还是能有效的降低端壁的热负荷 ,其中以中吹风比双排孔喷射的效果最为显著。刘高文 刘松龄 朱惠人 Lapworth B L Forest A E 2001航空动力学报2001,16,3:15

11Targeted sequencing supports morphology and embryo features in resolving the classification of Cyperaceae tribe Fuireneae s.l.显示文摘Molecular phylogenetic studies based on Sanger sequences have shown that Cyperaceae tribe Fuireneae s.l.is paraphyletic.However,taxonomic sampling in these studies has been poor,topologies have been inconsistent,and support for the backbone of trees has been weak.Moreover,uncertainty still surrounds the morphological limits of Schoenoplectiella,a genus of mainly small,amphicarpic annuals that was recently segregated from Schoenoplectus.Consequently,despite ample evidence from molecular analyses that Fuireneae s.l.might consist of two to four tribal lineages,no taxonomic changes have yet been made.Here,we use the Angiosperms353 enrichment panel for targeted sequencing to(i)clarify the relationships of Fuireneae s.l.with the related tribes Abildgaardieae,Eleocharideae,and Cypereae;(ii)define the limits of Fuireneae s.s.,and(iii)test the monophyly of Fuireneae s.l.genera with emphasis on Schoenoplectus and Schoenoplectiella.Using more than a third of Fuireneae s.l.diversity,our phylogenomic analyses strongly support six genera and four major Fuireneae s.l.clades that we recognize as tribes:Bolboschoeneae stat.nov.,Fuireneae s.s.,Schoenoplecteae,and Pseudoschoeneae tr.nov.These results are consistent with morphological,micromorphological(nutlet epidermal cell shape),and embryo differences detected for each tribe.At the generic level,most sub-Saharan African perennials currently treated in Schoenoplectus are transferred to Schoenoplectiella.Our targeted sequencing results show that these species are nested in Schoenoplectiella,and their treatment here is consistent with micromorphological and embryo characters shared by all Schoenoplectiella species.Keys to recognized tribes and genera are provided.Julian R.Starr Pedro Jiménez-Mejías Alexandre R.Zuntini Étienne Léveillé-Bourret Ilias Semmouri Muthama Muasya William J.Baker Grace E.Brewer Niroshini Epitawalage Isabel Fairlie Félix Forest Izai A.B.Sabino Kikuchi Lisa Pokorny Isabel Larridon 2021Journal of Systematics and Evolution2021,59,4:1

14A new classification of Cyperaceae (Poales) supported by phylogenomic data显示文摘Cyperaceae(sedges)are the third largest monocot family and are of considerable economic and ecological importance.Sedges represent an ideal model family to study evolutionary biology due to their species richness,global distribution,large discrepancies in lineage diversity,broad range of ecological preferences,and adaptations including multiple origins of C4 photosynthesis and holocentric chromosomes.Goetghebeur′s seminal work on Cyperaceae published in 1998 provided the most recent complete classification at tribal and generic level,based on a morphological study of Cyperaceae inflorescence,spikelet,flower,and embryo characters,plus anatomical and other information.Since then,several family-level molecular phylogenetic studies using Sanger sequence data have been published.Here,more than 20 years after the last comprehensive classification of the family,we present the first family-wide phylogenomic study of Cyperaceae based on targeted sequencing using the Angiosperms353 probe kit sampling 311 accessions.In addition,62 accessions available from GenBank were mined for overlapping reads and included in the phylogenomic analyses.Informed by this backbone phylogeny,a new classification for the family at the tribal,subtribal,and generic levels is proposed.The majority of previously recognized suprageneric groups are supported,and for the first time,we establish support for tribe Cryptangieae as a clade including the genus Koyamaea.We provide a taxonomic treatment including identification keys and diagnoses for the 2 subfamilies,24 tribes,and 10 subtribes,and basic information on the 95 genera.The classification includes five new subtribes in tribe Schoeneae:Anthelepidinae,Caustiinae,Gymnoschoeninae,Lepidospermatinae,and Oreobolinae.Isabel Larridon Alexandre R.Zuntini Étienne Léveillé-Bourret Russell L.Barrett Julian R.Starr AMuthama Muasya Tamara Villaverde Kenneth Bauters Grace E.Brewer Jeremy J.Bruhl Suzana M.Costa Tammy L.Elliott Niroshini Epitawalage Marcial Escudero Isabel Fairlie Paul Goetghebeur Andrew LHipp Pedro Jiménez-Mejías Izai ABSabino Kikuchi Modesto Luceño JoséIgnacio Márquez-Corro Santiago Martín-Bravo Olivier Maurin Lisa Pokorny Eric HRoalson Ilias Semmouri David A.Simpson Daniel Spalink WWayt Thomas Karen L.Wilson Martin Xanthos Félix Forest William J.Baker 2021Journal of Systematics and Evolution2021,59,4:1
