- The key role of an efficient post-processing with FieldView in the Dallara CFD Process
- Simona Invernizzi, CFD Manager, CFD Department, Dallara Automobili SpA
Elisa Serioli, CFD Methodologist, CFD Department, Dallara Automobili SpA
- Nowadays the CFD simulation is an essential tool since the supporting information and awareness provided for a state-of-art aerodynamic development of a racing car. In this respect Dallara, a Company located in the Parma area and working in Motorsport and Automotive services, invested a lot in the simulation tools (hardware and software) in order to get the maximum benefit in optimizing different products. In particular, for the CFD tool, it is fundamental to speed up every phase of the CFD process in order to get the most accurate results in the shorter time and, moreover, deriving the most useful information from the amount of data generated, this for sure through smart and efficient post-processing. In this context we will present the role of the FieldView tool in achieving the target of the process speed up and managing the most significant information coming from the CFD simulation.

- Surrogate-modelling the effect of building shape on the local wind microclimate through multi-directional, multi-fidelity CFD
- Aidan McLoughlin , CFD Engineer: WSP in the UK

- Formation of Vortices in Idealised Branching Vessels: A Parametric Validation Study with HELYX and Dakota
- Rudolf Hellmuth , Vascular Flow Technologies in the UK
- Atherosclerosis, the leading causes of death in the developed world, preferentially occurs near the junction of branching vessel, where blood recirculation tends to occur. Studies have shown that the endothelial cells covering the inside of blood vessels develop an atherogenic phenotype when exposed to low wall shear stress in recirculation zones. In 1980, Karino and Goldsmith mapped the the formation of eddies in glass models of circular branching junctions of various branching angles, diameter ratios, and Reynolds numbers (up to 350). These models served as idealized models of branching blood vessels in mammalian circulatory systems.
For decades, CFD has been used to predict flow patterns such as separation and recirculation zones in hemodynamic models, but those predictions have rarely been validated with experimental data. Recently, a technical standard was issued by the American Society of Mechanical Engineers to guide the execution of verification and validation (V&V) procedures to demonstrate credibility and fidelity of computational models in the medical device industry (ASME V V 40 - 2018). In the context of V&V, we set a parametric setup using Dakota to automatically run more than 12,000 CFD simulations using HELYX, where the whole range of parameters of the experiment of Karino and Goldsmith (1980) were covered. The critical Reynolds number for both the formation of the main vortex (MV), in the main branch, and side vortex (SV), in the side branch, was automatically detected and saved into a a table data. Therefore, it was shown that HELYX is able to correctly predict the critical Reynolds of vortices, which validates the use of this CFD package to predict the same kind of vortices in patient-specific branching blood vessels.

- Increasing Automation in the CFD Mesh Generation Process
- Richard J Matus, Ph.D. Executive Vice-President, Pointwise, Inc.
- Pointwise is known for providing explicit meshing control and the flexibility to easily integrate into customers’ design and analysis processes resulting in highly efficient and accurate CFD simulations. Recent developments have focused on automating the meshing process to achieve both precise meshing and ease-of-use. Details of new features like voxels and automatic surface meshing as well as upcoming automation-directed developments will be shown. The benefits of these approaches will be illustrated with example application and benchmark cases. A product roadmap will show Pointwise’s future direction toward making fully automatic, high quality meshing invisible to the user.

- High-Fidelity Modeling of sCO2 Cycle Components: Compressors and Direct-Fired Combustors
- Ashvin Hosangadi, Ph.D. , Vice-President , CRAFT Tech.
- This presentation will focus on technical issues and simulation challenges in modeling sCO2 compressors and oxy-combustors for direct fired cycles at off-design conditions. The CRUNCH CFD® framework features advanced capabilities for modeling subcritical operation of sCO2 compressors and has been extensively validated. Results for subcritical operation of the Sandia compressor will be presented. Oxy-combustors in direct fired sCO2 cycles operate at high pressures (~300 bar) with large amounts of CO2 recycled as diluent to achieve a low exit temperature (~1150 K). There is a large design space for optimally splitting the CO2 between the injector and chamber wall for cooling. A comprehensive modeling framework for high-fidelity design support is presented and physics affecting flame stability and combustor performance are identified.

- Japan Aerospace Exploration Agency (JAXA) has been using CRUNCH CFD in developing the first-stage engine LE-9 for Japan's new flagship launch vehicle ”H3”.
As the inside of the Liquid Rocket Engine is multi-physics environment involving real fluid physical properties, heat transfer, combustion and phase change, etc. under wide range of pressure and temperature conditions, it is very complicated to handle with conventional CFD solvers. In this talk lecture, the example of the initiative development of the simulation technology in cooperation with the software developer, CRAFT Tech, for the past 10 years will be introduced.
