Computational CFD Simulation and Experimentation Engineering
Both Require Profound Understanding of Physical Phenomena
".......It is important to repeat again, that computational simulation and ingenious experimentation engineering have their exclusive strengths and weaknesses and can not replace each-other, particularly for the cutting-edge performance, but if properly integrated, will strongly complement each-other, resulting in a synergistic outcome. “With unprecedented advances in computational software and hardware, it is now possible for more people to get bad results faster and cheaper than ever before.” The message behind this quote is that many software are becoming more and more sophisticated, with more and more features and user friendlier, but we have to be very careful about how to use it and how to interpret and justify simulation outcomes. Profound understanding of physical phenomena and software features and constrains are very critical in properly setting-up simulations and outcomes justifications. Tendency of use of CFD simulation software by fluid/thermal non-experts is risky at best and may be costly. It is equally true for setting up a good experimental testing. " (by M. Kostic)

Hydraulics and Aerodynamics Research in Transportation Applications Project (Profs. Kostic & Majumdar) is defined in collaboration with Argonne National Laboratory (ANL; Dr. Tanju Sofu-BridgeHydraulics&scour*R[N] b-c) as part of wider collaborations between Argonne National Laboratory (ANL), Turner-Fairbank Highway Research Center (TFHRC), University of Nebraska in Omaha (UNeb), and Northern Illinois University (NIU). The Computational fluid dynamics (CFD) based simulation techniques are being developed and evaluated by all four organizations to validate the CFD models based on the reduced scale experiments conducted at TFHRC hydraulics laboratory .
"The CFD simulations will address a range of hydraulics and aerodynamics research including, but not limited to, the assessment of lift and drag forces on bridge decks under various flood and wind conditions, optimization of bridge deck shapes to minimize pressure flow scour, analysis of sediment transport and its influence on scouring, evaluation of active or passive scour countermeasures to mitigate the damage, and addressing environmental issues such as fish passage through culverts. The applicability of the commercial CFD codes such as Star-CD and Fluent for prediction of these phenomena will be investigated, and the agreement between the code predictions and experimental data will be evaluated for various modeling options (NIU-P1)."

For MEE 340 Students: Study posted Handout (PDF-B&W) and online Help and get acquainted with Fluent's FLOWLAB CFD application software available in our Computer Lab: "The FLOWLAB educational software package is designed to be a virtual fluids laboratory which uses CFD to teach and visually reinforce concepts in fluid flow and heat transfer, and to introduce you to the effective use of CFD for solving fluid flow problems. FLOWLAB receives user input by means of its Graphical User Interface (GUI). A part of the FLOWLAB GUI is problem dependent. This is managed by a problem specific template file. A user session is referred to as a job and a template is used to create multiple jobs. FLOWLAB provides a seamless integration of CFD preprocessor, solver, and postprocessor. FLOWLAB uses GAMBIT for preprocessing and postprocessing. It uses FLUENT for solving a fluid flow problem."
