International Journal of CFD Case Studies - Volume 6

NAFEMS International Journal of CFD Case Studies

Volume 6, March 2007

ISSN 1462-236X
https://doi.org/10.59972/qtz1ankx



The papers in this sixth edition of the Journal are mainly the fruits of a NAFEMS Seminar. The many NAFEMS International groups are warmly encouraged to participate by sending their CFD seminar papers for publication, details may be found at the end of the Journal.


The now well-established CFD seminar held in Niedernhausen, in Germany under the guidance of Dr Moris Habip has provided further papers. Some papers from the seminar “Simulation of Complex Flows (CFD) – Application and Trends”, May 2004,were also published in the 5th edition of the Journal. The papers here deal with topics of CFD complexity whether of fluid-structure interaction, of geometrical shape requiring polyhedral meshing, or of complex properties inviscoelastic flow modelling.

The two remaining papers deal with the important subject of CFD validation and verification. The Quality and Reliability in CFD II: Industrial Challenges, September 2005, has provided a paper discussing the situation, common in complex flow combustion, where detailed corroborating measurements are not always available.

The final paper adopts a hierarchical approach to the verification and validation of an IMPNS space-marching flow solver applied to a complete hypersonic air-vehicle.

Further Details

Each of these case studies has been reviewed by members of the CFD working group to ensure that the paper includes:

  • A full description of the industrial relevance of the case study and why it has been performed;
  • A full description of related experimental or analytical data, together with statements as to their quality and accuracy;
  • A description of the CFD model which allows the interested reader to fully appreciate how it simulates the given industrial case;
  • The CFD model is detailed covering the flow physics, geometry, meshing, boundary conditions, fluid properties and the solving processes;
  • A set of results are presented and discussed to facilitate the reader’s appreciation that the work has been performed well and to a high standard.

Any Journal is only as good as the papers it publishes, so the Journal needs contributors who see the importance and benefit of having their work published and used by fellow engineers. Engineers are by nature supportive of colleagues, and authoring a case study paper for the Journal gives senior engineers an opportunity to pass on their hard won knowledge and experience, and in some sense “set the standard” of practice in the field. The Journal publishes CFD case study papers, i.e. investigations, simulations and validation exercises in accordance with CFD best practice guidelines. Original papers covering either traditional CFD, multi-phase flows, combustion and topics such as parallel computing, immersed boundary methods, DNS, LES, FSI, LBM, DEM, etc. are welcomed, book reviews and letters to the Editor are also acceptable.

Potential contributors are welcome to contact the editor, Professor Don McGlinchey at cfd.journal@nafems.org to discuss any aspect of the Journal and the process, from authoring to review to publication. Further details are available here.
