    A Tutorial on a Unified Approach for Computational Aeroelasticity

    Sunday, 7 January 2018
    1530-1730 hrs
    Aeroelasticity consists of the modeling and understanding of the interactions between the structural dynamics and unsteady aerodynamics of a configuration such as an airplane, a launch vehicle, or a bridge.  By its very nature, aeroelasticity is a multi-disciplinary field and can, therefore, include other disciplines such as controls (aeroservoelasticity) and thermal effects (aerothermoelasticity).  Over the last few years, the field of aeroelasticity has been transitioning from its classical origins involving linear, frequency-domain methods to more modern, nonlinear, computational-based methods.  The study and application of aeroelasticity involves the evaluation of critical loads and dynamics problems including, for example, gust loads and flutter.  While flutter, a dangerous condition that can result in damage or destruction of the structure, is a serious safety concern that needs to be addressed, there are also other aeroelastic concerns that address the structural health and longevity, as well as performance, of the vehicle.

    Verification and Validation Best Practices for Integrated Computational Materials Engineering

    Wednesday, 10 January 2018
    1430-1630 hrs
    Due to the exponential increase in the availability of computing power over the last several decades, modeling and simulation have become an important part of virtually all aspects of science, engineering, and manufacturing.  For modeling and simulation to achieve the Integrated Computational Materials Engineering (ICME) stated goal of delivering tools that aid the science and engineering decision making process, thorough and unbiased assessments of the accuracy and credibility of model results are critical.  This tutorial will provide an overview of the topics of Verification and Validation (V&V) and Uncertainty Quantification (UQ), demonstrated by contextualized examples, with a focus on the process and quantifying the confidence that can be attributed to results of computational materials science models.  While these topics have been investigated for decades in the computational fluid dynamics and structural analysis communities, the ICME community is just starting to grapple with implementing these issues and will face some unique challenges due to the range of physical phenomena that are of interest to the materials science community.

    Recent Advances in Alternative Fuels Combustion

    Wednesday, 10 January 2018
    1800-2000 hrs
    The tremendous expansion of the aviation demand combined with the energy crisis and the stringent environmental pollution regulations has been the challenge and the driving force for the alternative fuels research. Potential drop-in alternative fuels offer the opportunity to provide immediate benefits. Majority of the studies available in public domain deals with just few aspects of alternative fuel research. In this training session we will present a review of current alternative fuels research followed with a wide range of topics that are important for alternative fuels research. The topics would include PM and gaseous emissions, impact of different aromatic species on PM and seal swell, fuel system compatibility issues, combustion instability and noise issues followed with impact on Lean Blowout Limits. Overall aim of the training would be to give overall prospective of alternative fuels research and issues.
