FlowVision at European Turbomachinery Conference 2017:
NREL Phase VI Calculations through FlowVision were presented at European Turbomachinery Conference, Stockholm, 2017.
ABSTRACT: CFD calculations of NREL Phase VI rotor under wide range of operation conditions were conducted using FlowVision software. Computations were performed for various wind speeds with axial inflow, constant RPM and constant blade pitch. The rotation of the blades was modeled via different approaches; steady-state with frozen rotor using rotating reference frame and transient with moving boundaries or sliding surfaces. In addition to this, an ‘Overlapping Boundary Layer (OBL)’ was implemented to resolve the boundary layer for a selected case. Turbulence models ‘k-ε-AKN and k-ω Shear Stress Transport (SST) were used and compared. Except the OBL case, FlowVision wall function approximation was employed for all calculations with y+ values between 30 and 100. Overall results were compared for all of the above-mentioned numerical approaches and showed good agreement with the experimental data. k-ω SST turbulence model is found to perform better to predict stall onset. The stall occurrence and general torque trend as a function of wind speed is fairly well captured. Comparisons of the static pressure distribution around blades with experimental data at different span-wise sections for different wind speeds are presented and good agreement is observed.

New Release Announcement:
Faster and more powerful than ever! FlowVision 3.09.05
We proudly announce release of new version 3.09.05 of the FlowVision CFD software. FlowVision 3.09.05 has already been successfully tested by FlowVision experts in our team and also by some of valuable key users on various tasks. Finally, it is accessible for all existing maintenance subscribers and expecting to meet new users!
One of the 20 test cases: Splashdown of a spacecraft moving in atmosphere air with activated landing-engines
We constantly work to improve quality and performance of FlowVision for more efficient solutions that serve the industry. The new version is coming with new features allowing a wider spectrum of advanced physics cases to be resolved and many important improvements for even better accuracy and stability of FlowVision for solution of various industrial tasks.
Our developers have implemented a new iterative algebraic solver, which substantially speeds up solution of many simulations while reducing the computation times by 25-40%. This means that being already equipped with a foremost powerful CFD solver, FlowVision is now also allowing users to compute much more variations in the same time duration providing shorter lead times and reduced costs. This new high-level of computational efficiency, as it is, goes for the HPC (high performance computing) configurations such as those on large clusters.
Percentage reduction in computation time (FV 3.09.05 vs FV 3.09.04) for 20 different test cases

Hanover Fair 2016: The BOGE compressor manufacturer uses FlowVision in a cloud to reduce the development costs
Small and medium-sized companies are interested in use of engineering software and high-performance computers. The EU’s project CloudFlow provides the both possibilities. 46 partner organizations from 13 European countries are working together in this project coordinated by the Fraunhofer Institute for Computer Graphics Research IGD. The project provides access to the numerical simulation software for small and medium-sized companies with using cloud computing on the CloudFlow platform. In this solution the existing servers provides high computational performance for solving difficult problems (High Performance Computing, HPC). Customers pay for computational power and the software only when they use these resources via Internet. Use of cloud technologies allows the customers to:
- use the software and infrastructure of high performance computations in a cost-effective way
- solve high dimension problems (complex part assemblies)
- carry out several optimization projects on supercomputers in a parallel mode
BOGE engineers succeeded in improving characteristics of compressors using the CloudFlow platform and the FlowVision CFD software package for computational hydro- and aerodynamics optimized for work in a cloud. The BOGE KOMPRESSOREN company is one of the oldest German manufacturers of compressors and it is one of the CloudFlow partners. The software used for development is important tool for achieving the high company’s requirements to quality of production. BOGE’s engineers work on on improving the machine's efficiency and reducing the noise level.
Results of the experiment for improving the characteristics of the BOGE compressors by the FlowVision computational hydro- and aerodynamics software package operating on the CloudFlow cloud platform were presented on the HANNOVER MESSE, April 25-29 2016.
CloudFlow is funded as a joint project within the scope of the 7th Research Framework Program of the European Commission (Grant Agreement No. 609 100)
