- Large Scale Coupling Simulations of Real Machines based on Partitioned Iterative Algorithms
- Professor Shinobu Yoshimura
School of Engineering, The University of Tokyo
- Various parallel dynamics analysis codes for fluid systems, structural systems, combustion systems, etc. are running in the state-of-the-art HPC environment such as Fugaku and are being used for solving large scale analysis of real machines. However, the coupled phenomena that are unavoidable in real machines are still only handled in small-scale and simple analysis on PCs and workstation environments. This presentation will introduce large-scale simulations of real machines based on partitioned iterative methods Professor Yoshimura and co-researchers have developed over more than 10 years, and it will introduce various application examples on Fugaku. Professor Yoshimura will also explain the knowledge and skills required for analysts when solving coupled problems of real machines based on his extensive experience.

- The latest Version (1.6) and application of VFBasis
- Akio Kawaguchi,PH.,D. Engineering Department 3, VINAS Co., Ltd.
- VFBasis is the world's first commercial package system for fluid vibration/noise analysis by POD/DMD machine learning processing.
This is a tool developed to automatically extract and classify typical periodic fluctuation components that were difficult to analyze in large-scale and complex unsteady fluid analysis result data, and to facilitate analysis. As for features, it is possible to understand dominant fluid vibration phenomena and identify noise sources by extracting feature structures (spatial patterns) and their temporal changes (frequency, amplification factor) at high speed and with less memory. In this presentation, we will introduce the new functions of VFBasis V1.6 and application examples.

In this presentation, two case studies are introduced. One is a fluctuating flow field analysis to investigate factors of aerodynamic force fluctuation acting on a vehicle body using mode decomposition technique with VFBasis. The other is a mode analysis to extract characteristic velocity distribution from aerodynamic analysis results of many vehicle shapes obtained in the optimization calculation process.

- Predicting High-Lift Aerodynamics on NASA Common Research Model - Part I: Reynolds Averaged Navier-Stokes Simulations
- NASA Ames Research Center, Jared Duensing
- An in-depth assessment of the High Lift Common Research Model (CRM-HL) aerodynamic performance is made using a Reynolds-Averaged Navier-Stokes (RANS) methodology within the Launch, Ascent, and Vehicle Aerodynamics (LAVA) framework. Results were produced in support of the 4th AIAA High Lift Prediction Workshop (HLPW-4), with additional simulation results and analysis used to support findings from the workshop. Mesh resolution, RANS closure models, and tunnel effects were among the sources of simulation sensitivity addressed, all in the pursuit of evaluating best-practice simulation methods for complex high-lift configurations. In general, free-air simulations using RANS yield accurate predictions of integrated loads in the pre-stall regime for the CRM-HL, while strong sensitivity to simulation method is observed near CLmax. Several available corrections for the Spalart-Allmaras (SA) turbulence model were tested and generally introduced more error relative to the experiment as compared to the baseline SA closure model. The Standard Menter Baseline Two-Equation (k-w BSL) turbulence model was also explored, which arguably yielded results highly consistent with experiment, but at a substantially higher computational cost. Therefore, as a compromise between computational cost and accuracy, the baseline SA closure model was selected for additional CRM-HL studies that assess alternative solution methods. These strategies include “warm start” approaches, unsteady calculations, and simulations that model the experimental wind tunnel. Results from these studies would reinforce the shortcomings of RANS in predicting aircraft performance at high-lift conditions, namely at high-a and highly loaded flap conditions, while also answering questions about appropriate modeling techniques to minimize the errors associated with RANS where possible.
