Objectives
·
The first
workshop will focus on ice shape comparisons between the 3D/2D codes for cases
where experimental ice shapes are readily available. The ice shapes would be generated on both 2D
and 3D geometries for a limited number of configurations and conditions.
·
The intent
is to establish a sound baseline of the current capabilities and use this
baseline to target the best topics for the follow-on workshops. This would maximize the number of
participants that are potentially interested in such a workshop and minimize
the risk of incomplete submissions.
·
There is
also strong interest in performing code-to-code comparisons of collection
efficiency which is possible for all cases and code-to-experiment comparisons
of collection efficiency where such data are available. It is recognized that a methodology for
geometric comparison of ice shapes is also needed and should be a topic of the
first workshop
General Information
·
These Ice
Prediction Workshops are collaborative in nature, aiming at assessing the icing
simulation tools and practices, identify areas of improvement and recommended
practices and at sharing knowledge. They should not, therefore, be viewed as
competition between codes, groups and/or testing facilities.
·
Ice
accretion is, in most cases, a 3D phenomenon and, therefore, 3D modeling and simulation is usually preferred.
·
Great
effort has been invested in the research, development, and testing of 2D icing
simulation. 2D analysis is still widely
used and well accepted. It established the groundwork for 3D methods and,
hence, it should be used as a valid reference for comparison whenever
applicable.
·
It is
important to define a methodology to compare the simulated 3D ice shapes among
themselves and with the 3D experimental ice shapes.
·
Icing
simulation typically involves four modules: airflow solver, droplet dynamics
solver, surface water mass and energy balance module, and ice accretion
geometry module. It is important, to try to understand how each module
contributes to discrepancies in the final ice shape prediction.
·
When
comparing numerical simulation results to experimental simulation results, the
uncertainty of both types of simulations needs to be considered, as well as the
repeatability of the experimental results at a given facility and, if possible,
between facilities.
·
Our intent
is to capture best practices in icing simulation, identify current limitations
of the 3D tools, and make recommendations about specific areas where more work
is needed.
