On the morning of March 4, we had an informal breakfast meeting with other members of the FED Executive Committee that were in attendance at the LTC. The attendees included Awatef Hamed, Dave Halt, Jinkook Lee, George Papadopoulos, and myself. One of the topics of discussion was the location of FEDSM2013. Awatef will the conference chair.

2011 ASME-JSME-KSME Joint Fluids Engineering Conference ACT Congress Center Hamamatsu, Japan July 24–29, 2011

he ASME-JSME-KSME Joint Fluids Engineering Conference 2011 (AJK2011-FED) has grown out of the ASME- T JSME Joint Fluids Engineering Conference that was first held in Portland, Oregon in 1991. From a global per- spective, the world faces a number of daunting challenges including global climate change, finite energy resources, and economic crises. These problems are wide-ranging and extremely complex. Mechanical engineering and mechanical engineers have the potential to overcome these problems. Three mechanical engineering societies, JSME, ASME and KSME, have been addressing these problems both individually and collaboratively. The ASME- JSME Joint Conference on Fluids Engineering has played a major role in addressing these challenges, but the problems are too complex to solve only through bilateral collaboration. We need global and industry-government-academia collaboration to find the answers. On this basis, the three societies have decided to hold the ASME-JSME-KSME Joint Conference on Fluids Engineering 2011 (AJK2011-FED) in Hamamatsu, Japan. The organizing committee of AJK2011-FED looks forward to the active participation of mechanical engineers and researchers from around the world. There are currently over 800 technical papers in process for this conference. The AJK conference will be held as scheduled. Please be assured that the conference venue, Hamamatsu, is very safe as it is far away, or 530 kilometers from Fukushima. For access, Central Japan International Airport is the near- est airport to the venue. 12 Spring 2011 FED Awards

2012 Fluids Engineering Division Summer Meeting

ocation and time: The 2012 Fluids Engineering Division Summer Meeting will be held as a Joint L Conference with ASME Summer Heat Transfer Conference, the Fluids Engineering Division Summer Meeting, and the International Conference on Nanochannels, Microchannels and Minichannels at the Wyndham Rio Mar Beach Resort in Puerto Rico from July 8 to July 12, 2012.

onference Description: This conference will bring together international researchers and engineers C focusing on heat and mass transfer and fluid flow in a variety of applications. The objectives of the meeting are to provide a forum for presentation of state-of-art research and opportunities for technical interactions among participants.

onference Topics: Contributions are being solicited on fundamental research and applications C related to heat and mass transfer and fluid mechanics from large-scale to nano-scale. Conference topics include applications in the areas of energy systems, combustion, aerospace, gas turbines, elec- tronic equipment, biotech, manufacturing, environment, multiphase flows, and nano-, micro-, and minichannels. Theoretical, fundamental measurements, flow visualization, and computational heat transfer and fluid dynamics are also welcomed. Website: http://www.asmeconferences.org/HTFNMM2012/
