At the meeting, the attendees discussed about the current trend and future directions in fluids research in civil engineering and proposed 6 specific topics (see item 6). It was concluded that new members should be recruited for the fluids committee in the following year in order to maintain a critical mass of active members for each of the important research areas.
Committee
members are encouraged to submit nominations of new members with their resume
to Dr. Alex Cheng, our ExCom contact person, before
Under the leadership of Dr. Keh Han Wang, the Fluids Committee organized 6 sessions for the EM-2003 conference. Among them, sessions No.54, 56, 57, 58 were organized in collaboration with the Turbulence Committee. The detailed session topics are given below:
Session 53: Sediment Transport
Session 54: Hydrodynamics and Transport Modeling
Session 56: Environmental Fluid Mechanics I: Experimental Studies
Session 57: Environmental Fluid Mechanics II: Numerical Methods
Session 58: Environmental Fluid Mechanics III: Numerical Simulations
Session 59: Fluid Mechanics Applications in Civil Engineering
Teng reported that during
the past 10 months (October 2002 – July 2003), the fluids committee received 19
papers submitted to JEM for review. Among the 19 papers, 12 are new submissions
and 7 are revised or resubmitted papers.
For the 12 new
submissions, 8 are from
- 3 tentatively accepted, re-review required;
- 1 declined with encouragement for resubmission;
- 2 declined, final;
- 4 currently under review;
- 1 returned to ASCE because the topic did not fit fluid mechanics;
- 1 directed to ASCE for number logging first; the authors sent the papers to the committee directly without going through the journals department first.
There is a need
to promote JEM among fluid mechanics scholars in civil engineering in the
4. Report on Completion of Editing of a Special Issue for JEM
In collaboration with the ASCE Turbulence Committee, the Fluids Committee (lead editor: Dr. Keh Han Wang) helped to edit a special issue for the J. of Engineering Mechanics with the theme “Advanced Experimental Techniques in Environmental Fluid Mechanics”. The fluids committee invited 6 papers, and after normal review, 4 were accepted and 2 were declined. The accepted papers cover the following topics: flow measurement by using Particle Image Velocimetry (PIV), new algorithm for PIV, new experimental techniques for studying sediment transport, and field technique for studying waves in harbors. The special issue will be published in October 2003.
Dr. Alex Cheng did an excellent job in
maintaining the committee web site (http://www.olemiss.edu/sciencenet/fluids/)
by frequently updating the committee members’ contact information and adding
committee documents (e.g., meeting minutes, conference announcement, etc). In
addition, Dr. Cheng also added a history (tracing back to 1979) of the fluids
committee by working with senior committee member Dr. Tin-Kan Hung and the ASCE
headquarters. All past committee members’ names can be found at the web site.
Dr. Cheng will continue to be the webmaster for our committee.

During the meeting, an excellent proposal was
made by several attendees to establish the following three awards for fluid
mechanics papers presented at each year’s Engineering Mechanics conference:
ASCE EMD Fluids Committee Best Annual Conference Paper Award in Research
ASCE EMD Fluids Committee Best Annual Conference Paper Award in Application
ASCE EMD Fluids Committee Best Annual Conference Student Paper Award
These awards may attract more participants to the ASCE EM conferences especially in the fluids area in the future.
This proposal
was reported to the Executive Committee on
Drs. Nik Katopodes, Ben Hodges, and Scott Yost will form the task force to
(1) prepare a document to explain
a. the background, objective and expected outcome of the awards;
b. detailed criteria and procedure for selecting papers to receive the awards.
(2) circulate the draft document among fluids committee members for review and comments
(3) obtain approval from the ExCom
(4) serve as the award selection committee at EM-2004
(5) consider establishing an ASCE EMD Fluid Dynamics Award (min. endowment: $25,000)
Donation sources: small donations from
individuals in several years; or one donor contributes $25,000 one time. In the
latter case, the award will be named after the donor.
9. Discussions on Compiling an Emailing List of Major Fluids Scholars in Civil Engineering
In order to effectively promote the ASCE Engineering Mechanics Division
and the ASCE Journal of Engineering Mechanics to the fluid mechanics community
in civil engineering, we plan to compile an emailing list of major fluids
scholars in civil engineering in the
Teng and Katopodes will prepare the first draft of the list and then send to the entire committee for review.
10. Discussions on Increasing the Number of Papers in Fluid Mechanics for J. of Engineering Mechanics
Fluid mechanics is an important branch of
engineering mechanics, however, the ASCE Journal of
Engineering Mechanics has remained relatively unknown to the fluids scholars in
civil engineering especially in the
(1) encourage fluids committee members to contribute papers to JEM;
(2) send promoting messages to reputed scholars in fluid mechanics;
(3) make the journal review process more effective and more efficient:
Teng has set up an implicit web link http://www.eng.hawaii.edu/~teng/JEM for the
authors to check the review status of their papers automatically and anonymously starting
The ASCE fluids
committee will co-sponsor the Theodore Y.T. Wu Symposium on Engineering
Mechanics to be held in
“Fluid
Mechanics Research and Education in Civil Engineering – Current Trend and
Future Directions
Occasionally, fluid mechanics may appear to some civil engineers as too classical a discipline with fewer applications in civil engineering as compared to solid mechanics and structural engineering. In reality, fluid mechanics has always played an important role in developing civil infrastructure and protecting the natural environment. Along with the development of faster computers and more advanced experimental instrumentation, researchers nowadays can solve more complex civil engineering problems (such as fluid-structure interaction) through fundamental fluid mechanics research (such as large scale numerical simulation) instead of the traditional empirical approach. As environmental issues become more and more important in civil engineering, fluid mechanics will also play a more important role in the civil engineering field since only through fundamental fluid research, we can fully understand the many important environmental processes such as the mixing and transport processes.
For the proposed international workshop, well-established and young scholars as well as NSF officers in fluid mechanics will be invited to attend. Participants will present their frontier research results demonstrating the important applications fluid mechanics to civil engineering. In addition, the participants will discuss about the future directions in fluid mechanics education and research relevant to civil engineering. Proceedings produced from this workshop will be published as a special ASCE publication. This special publication can be helpful in promoting fluid mechanics and providing guidance for future research directions, and may even have an impact on future funding levels for research in fluid mechanics in civil engineering.
Teng and Katopodes will prepare the first draft of the proposal.
Dr. Joseph Lee, chair of the Turbulence Committee, has proposed to edit a special issue for the Journal of Engineering Mechanics on “Environmental Hydraulic Processes”. Drs. Ben Hodges and Scott Yost from the Fluids Committee will collaborate with Dr. Lee as co-guest editors for the special issue.
It was noted that quite a large number of
computational fluid dynamics codes with applications to civil engineering have
been developed and commercialized in the US and abroad. However, so far, these
codes have not been evaluated by a professional organization using same uniform
tests. As a result, aside from the developers’ own descriptions, there is no
clear understanding by the engineering community of the true performance
(accuracy, efficiency, and robustness) of the existing codes. During the
committee meetings, Dr. Sanders made an excellent suggestion that the fluids
committee begin developing a database of benchmark experimental and numerical
tests for evaluating the performance of existing numerical codes in fluid
mechanics. This database can be a great service to both the research community
and the engineering community in the fluids area.
