Alcune prestigiose referenze delle soluzioni CFD di NUMECA International

• ROLLS-ROYCE
  If you are tired of "meshing around", need a robust and easy to use CFD-package and you are dealing with turbomachinery, NUMECA's FINE/Turbo is, at present, the best choice.
  
  
• MAN TURBO
  The system is close to push-button CFD, which is exactly what our company is looking for.
  
  
• ABB TurboSystems
  The R&D department of ABB Turbo Systems Ltd decided to extend the use of FINE/Turbo, which becomes our reference commercial 3D NS CFD tool.
  
  
• SOLAR TURBINES
  We have been using FINE/Turbo? very successfully to tune the performance on an 11 stage compressor by modifying some new front stages, we were able to improve the overall efficiency by a point over the first attempt.
  
  
• MIT (Massachussetts Institute of Technology)
  At MIT we have been using Fine Turbo for a year now on compressor design. It is very user friendly and is pretty fast with the multigrid solver.
  
  
• DOTY Scientific
  We chose FINE/Turbo 4.1 ~2.5 years ago over TaskFlow and Fluent primarily because of the relative ease (minimum number of key strokes per iteration) with which we could modify and optimize our radial-flow and mixed-flow turbines and compressors. We also found Numeca to be ~40% faster than CFX and three times faster than Fluent. We also did some experimental validation studies for micro nozzles and found better experimental agreement with Numeca, though the others were also quite close.
  
  
• MAFI-TRENCH
  We have used FINE/Turbo for about 4 years now, for use in a wide variety of single-phase fluid flows. We chose it based on the user-friendliness and the ability to interface the Concepts' 3-D blade design software (CCAD). In 1998 FINE was already available for a WindowsNT platform, which has proved to be a substantial benefit due to the low cost of hardware upgrades (which means more frequent upgrades). We have found very good agreement between the CFD results and test results. Over the last four years the grid generator, solver interface and the solver itself have seen very positive development, and Numeca has provided a high level of support. I would highly recommend Fine/Turbo.
  
  
• MAN B&W
  As a key player in the field of high pressure turbocharging we have chosen the NUMECA Fine/Turbo software suite for its inherent capability of simulating transonic turbomachinery flows with excellently adapted numerical approaches. .... As regards accuracy, robustness, and computational efficiency, Fine/Turbo exhibits excellent capabilities for our applications, such as full transonic centrifugal compressors and turbines including volutes as well as axial flow turbines. A few remarks to pre and postprocessing: 1. Turbomachinery cascade gridding is highly convenient by virtue of the IGG/Autogrid module 2. Complex geometries, e.g. volutes or ancillaries are meshed by the IGG module, which exhibits numerous convenient features to set up complex multi block grids involving full non matching boundaries 3. Post processing is greatly enhanced by an easy to learn macro language, which includes all required options. Finally, we would like to emphasize excellent and fast support by NUMECA."

• THERMODYN - GENERAL ELECTRIC
  Hexpress is very simple to use and truly automated. Our more complex geometriesare perfectly matched with full hexahedra meshes. Above all, needed input time for grid settings is highly reduced.
  
  
• SBW (Shenyang Blower Works)
  We have done several computations of centrifugal compressors, which help us a lot in the flow field analysis and design improvements. The computation speed, including mesh generation and post-processing, is quite fast with our PC computers". "The accuracy of overall performance, got with about 40,000 mesh points, is within 3% difference compared with our data.
  
  
• HONEYWELL Engine
  I would recommend that you consider Numeca Inc.'s Fine/Turbo code. I have been using this code for multistage analysis of both high and low pressure turbines and I am very pleased with the results. Thanks to its AutoGrid utility it is a matter of an hour or less to come up with a decent, orthogonal, 3D, periodic mesh around multiple blade rows. Also, the convergence is very robust and fast thanks to the multigrid accelaration. I have carried out a comparative study where I compared the results from Fine/Turbo to results from a viscous, 3D, government code and found out that the convergence rate and levels of residuals were much better with Fine/Turbo and the accuracy was as good, if not better. Also, I have simulated some test cases from the literature and found out that the loadings are in excellent agreement with the data. I am also aware of a study where Fine/Turbo was evaluated against some other commercial and government codes and it was found to be more suitable for multi blade row analysis. Finally, their consulting engineers are highly knowledgeable in CFD and are very helpful.

I am an aerodynamics design engineer in the Turbine Aerodynamics group at Honeywell ES&S. Here at Honeywell, we have access to many CFD codes, both commercial and government owned, and I have had had the opportunity to work with most of them. Based on my past experiences with all these CFD tools, I feel fortunate that we have actually chosen to adopt Fine/Turbo as our standard aero design and analysis tool in the turbine aero group. ... We rated several codes based on the ease of model generation, mesh quality, robustness and speed of the solver, and postprocessing capabilities. After also comparing the results from various codes to our rig test data, we have decided to adopt Fine/Turbo over the others. ... Numeca's automated mesher, AutoGrid is an excellent tool for generating 3D mesh around axial/radial airfoils and splitter/tandem vanes. One can generate smoothed H-type and O type grids very quickly using templates. The multigrid accelerator allows for rapid convergence. For big tasks, I found the parallel capability to be also very useful. The postprocessing capability is very user friendly, visual and also quantitative. One can easily select surfaces or create cutting planes and plot velocity vectors or contours of various quantities on these planes. Various macros, allow us to generate mass averaged quantities, both 1D and radial. But in my mind the biggest winner is Numeca's general purpose mesher, IGG. Thanks to that, I am actually using Fine/Turbo not only for multi-stage turbine analysis but for all my CFD needs.. Usually, the geometry is developed by a designer and passed on to us as an IGES file and it is not always the best quality. .... Since with IGG you are actually meshing the blocks that are attracted/wrapped around/and projected onto the geometry, you don't need to spend time with geometry cleanup. I find this extremely useful. ..." Hakan Aksoy
  
  
• HIT (Harbin Institute of Technology)
  We have done cooling flow, steady and unsteady computations of axial turbines and multi-stage axial compressors with NUMECA's software. Compared to other commercial CFD codes we have, the interfaces in NUMECA's is quite user-friend. The speed and mesh quality got with the mesh generator IGG/Autogrid is higher than the others. The numerical accuracy for our all test cases fit our requirement. In addition, the RAM memory required by NUMECA software is much lower than the others. In one of our research project, we can run it with NUMECA's Fine/Turbo, but can not run it with the other codes in the same computer with the same mesh points.
