During FY2022, Dr Lusher has published 1 journal paper [1] and 2 international and 1 domestic conference papers [2,3,4]. A poster presentation was also made at SuperComputing22 conference, USA. Oral presentations were made at both domestic and international conferences. Dr. Lusher was awarded a Junior Researcher computational grant for 153.6 Million Core Hours on the Fugaku supercomputer at RIKEN. A research visit was made to NASA Langley Research Center, USA, in January 2023, for collaborative research and to present a seminar. The OpenSBLI code has been extended to be able to simulate high-fidelity simulations of transonic airfoil buffet. The code has been validated against data in the literature [2], and its performance has been tuned on both JAXA’S JSS3 supercomputer and Fugaku.

于2022财政年度，Lusher博士已发表1篇期刊论文[1]及2篇国际及1篇国内会议论文[2，3，4]。在美国SuperComputing22会议上也作了海报介绍。在国内和国际会议上作了口头介绍。Lusher博士获得了RIKEN Fugaku超级计算机1.536亿核心小时的初级研究员计算补助金。2023年1月赴美国NASA兰利研究中心考察，进行合作研究并举办研讨会。OpenSBLI代码已经扩展到能够模拟跨音速翼型抖振的高保真模拟。该代码已根据文献[2]中的数据进行了验证，其性能已在JAXA的JSS3超级计算机和Fugaku上进行了调整。
