9522968 Kudaravalli This proposal supports the collaboration of Dr. Ravikumar Kudaravalli of the Department of Chemical Engineering at the University of California, Los Angeles and Professor Yoichi Matsubara of the Atomic Energy Research Institute (AERI) at the Nihon University, Chiba. Project funding will enable Dr. Kudaravalli to spend one year in Japan, resident at Nihon University, in order to investigate the thermal and fluid dynamics phenomena for design of cryogenic pulse tube cooler components for optimum performance. Dr. Kudaravalli has previously investigated the heat transfer, fluid dynamics and thermodynamic aspects of various cryogenic systems in general and heat exchangers and regenerators of cryocoolers including pulse tube coolers in particular. Professor Matsubara is one of the leading researchers in the pulse tube cryocooler area. He has pushed the technology further by multistaging of the cooler and by invention of the regenerative tube. Professor Matsubara's demonstration of liquid helium temperatures (3.6 K) is the record low temperature ever produced by a pulse tube cryocooler. Dr. Kudaravalli will combine his expertise with that of Professor Matsubara to study the thermal and fluid dynamics phenomena in cryogenic pulse tube coolers achieving optimum performance. This proposal brings together research scientists from two countries working in the area of advanced cryogenic cooler technology. The U.S. scientist will have the opportunity to become familiar with research techniques, equipment and facilities at AERI while contributing to the overall research effort. Therefore, this proposal fulfills the objectives of the program in its exchange and transfer of scientific knowledge through an international collaboration. ***

9522968 Kudaravalli该提案支持加利福尼亚大学洛杉矶分校化学工程系的Ravikumar Kudaravalli博士和原子能能源研究所（Aeri）的Yoichi Matsubara教授（AERI），吉巴（Chiba）。项目资金将使Kudaravalli博士能够在日本（日本居民）度过一年，以研究用于设计低温脉冲管冷却器组件的热和流体动力学现象，以实现最佳性能。 Kudaravalli博士此前曾研究过各种低温系统的热传递，流体动力学和热力学方面，以及尤其是包括脉搏管冷却器在内的冷冻机的再生器和再生器。 Matsubara教授是Pulse Tube Cryocooler地区的主要研究人员之一。他通过散热器的多阶段和再生管的发明来进一步推动技术。 Matsubara教授的液态氦气温度（3.6 K）是脉搏管冷冻机曾经产生的创纪录的低温。 Kudaravalli博士将将他的专业知识与Matsubara教授的专业知识相结合，以研究低温脉冲管冷却器中的热和流体动力学现象，可实现最佳性能。 该提案汇集了来自高级低温冷却器技术领域工作的两个国家的研究科学家。美国科学家将有机会熟悉AERI的研究技术，设备和设施，同时为整体研究工作做出贡献。因此，该提案通过国际合作来实现该计划的交换和科学知识转移的目标。 ***
