U.S. Japan Long-Term Research Visit: Diesel Combustion Modeling and Inlet Port Geometrical Effects on Flow and Combustion

该奖项将促进威斯康星大学的Jay Martin教授与札幌北海道大学的Tadashi Murayama教授和Takemi Chikahisa教授在项目的一个阶段的合作。第二阶段是Martin教授和日产汽车公司中央工程实验室高级研究员Yasuv Takagi的合作。与北海道大学的计算研究将侧重于开发一种改进的柴油燃烧模型，用于多维流体力学代码KIVA-II。与日产汽车公司的实验研究将包括建立一个粒子图像测速（PIV）系统，用于测量往复式发动机进气部分的速度流体。这两项研究都可能在建模和气缸流动的重要领域为先进内燃机的设计做出重大贡献。所有参与的研究人员在他们的专业领域都是非常合格的。马丁教授在发动机激光测速方面有丰富的经验，在发动机建模方面有坚实的基础，使用KIVA是最广泛使用的气缸发动机建模代码。威斯康星大学和北海道大学都是世界柴油燃烧研究的两个中心。此外，北海道大学和日产汽车公司都在高质量的研究方面享有国际声誉。预计在正式项目完成后，研究人员之间建立的密切联系将长期持续下去。

This award will facilitate cooperation between Professor Jay Martin of the University of Wisconsin, and Professors Tadashi Murayama and Takemi Chikahisa at Hokkaido University in Sapporo for one phase of the project. The second phase involves collaboration between Professor Martin and Yasuv Takagi a senior researcher with the Central Engineering Laboratories of Nissan Motor Company, Ltd. The computational research with Hokkaido University will focus on the development of an improved diesel combustion model for use in the multidimensional fluid-mechanics code KIVA-II. The experiment- al research with Nissan Motor Company will involve the set up of a Particle-Image-Velocimetry (PIV) system for measuring the velocity fluid in the intake part of a reciprocating engine. Both studies are likely to contribute substantially to the design of advanced combustion engines in important areas of modeling and incylinder flows. All of the researchers involved are highly qualified in their areas of expertise. Professor Martin has extensive experience in laser velocimetry in engines and a solid base in engine modeling using KIVA which is the most widely used code for incylinder engine modeling. Both the University of Wisconsin and Hokkaido University are two of the world centers of diesel combustion research. In addition, both Hokkaido University and Nissan Motor Company have an international reputation for quality research. It is anticipated that the close ties developed between the researchers will continue long after the formal project has been completed.
