Team 4: Simulation of Jet Mixing in Supersonic Flow with Shock

team-30b

This team project focused on simulating jet mixing in supersonic flow with shock. One important finding was that remote visualization provided possibilities for remote, very large data management, limiting the unpleasant (and unavoidable) remote-rendering delay effect.

Resources used by the team
• openFOAM Solver (sonicFoam)
• web interface provided by CILEA

Team 15: Weather Research and Forecasting on Remote Computing Resources

team 15a

In this HPC Experiment, the team attempted to evaluate the performance of WRF (Weather Research & Forecasting) open software on a remote compute cluster, which is larger than the end-user’s existing computing cluster.

Currently, it has been empirically determined that the improvement in the system performance becomes negligible with an increase in the number of parallel computing cores beyond the current 96 computing cores. With the usage of applicable High Performance Computing methods, the team investigated if it is feasible to reduce the overall processing time of the WRF software and thus provide faster weather predictions and/or higher-resolution predictions as well.

Team 20: NPB2.4 Benchmarks and Turbo-machinery Application on the Amazon EC2 Cloud

turbo-machinary-simulation

The team used an application from machinery manufacturing in this experiment. The engineers who use CAE software on physical workstations or compute clusters can do the same operations on cloud resources based on their skills and knowledge of creating, configuring and connecting to instances on the Amazon EC2 Cloud.

Team 34: Analysis of Vertical and Horizontal Wind Turbines

Team34

The goal was to optimize the design of wind turbines using numerical simulations. The case of vertical axis turbines is particularly interesting, since the upwind turbine blades create vertices that interact with the blades downstream. The full influence of this can only be understood using transient flow simulations, requiring large models to run for a long time.

Team 36: Advanced Combustion Modeling for Diesel Engines

diesel-engines

Modeling combustion in Diesel engines with CFD is challenging. The physical phenomena occurring in the short combustion cycle are not fully understood. This especially applies to the liquid spray injection, the auto-ignition and flame development and formation of undesired emissions like NOx, CO and soot.

A model designed to address these types of challenging cases where combustion initiating chemistry plays a large role has been implemented in ANSYS Fluent and was validated.

Team 44: CFD Simulation of Drifting Snow

Team44

Simulation of drifting snow for the purposes of predicting the redistribution of accumulated snow by the wind around arbitrary structures. Such computations can be used to determine the snow load design parameters of rooftops, which are not properly addressed by building codes at the present.

Team 52: High-Resolution Computer Simulations of Blow-off in Combustion Systems

combustion

The undesired blow-off of turbulent flames in combustion devices can be a very serious safety hazard. Hence, it is of interest to study how flames blow off. Simulations offer an attractive way to do this, however, due to the multi-scale nature of turbulent flames, and the fact that the simulations are unsteady, these simulations require significant computer resources.

In this project, a canonical test problem of a turbulent premixed flame is simulated with OpenFOAM.

Team 54: Analysis of a Pool in a Desalinization Plant

team54

Many areas in the world have no available fresh water even though they are located in coastal areas. As a result, in recent years a completely new industry has been created to treat seawater and transform it into tap water. This water transformation requires that the water must be pumped into special equipment, which is very sensitive to cavitation.Therefore, a correct and precise water flow intake must be forecasted before building the installation.
The CFD analysis of air-water applications using free surfaces modeling is a highly complex modelization. The computational mesh must correctly capture the fluid interface and the number of iterations required to obtain physically and numerically converged solution is very high. If both previous requirements are not matched, the forecasted solution will not even be close to the real world solution.

Team 56: Simulating Radial and Axial Fan Performance

team56

For the end user the aim of the exercise was to evaluate the HPC cloud service without the need to obtain new engineering insights. That’s why a relatively basic test case was chosen a case for which they already had results from the end user’s own cluster, and which had a minimum of confidential content. The test case was the simulation of the performance of an axial fan in a duct similar to those found in the AMCA standard. A single ANSYS Fluent run simulated the performance of a fan under 10 different conditions to reconstruct the fan curve. The mesh consisted of 12 million tetrahedral cells and was suited to test parallel scalability.

Team 58: Simulating Wind Tunnel Flow Around Bicycle and Rider

team-58a

Trek Bicyle, the end-user of this project, has been heavily investing in engineering R&D, and does extensive prototyping before producing a final production design. CAE has been an integral part of design process in accelerating the pace of R&D and rapidly increasing the number of design iterations. Advanced CAE capabilities have helped Trek reduce cost and keep up with the demanding product development time necessary to stay competitive.

Team 60: Simulating unsteady flow around an aircraft landing gear

Tem60

Team 60 focused on setting up and successfully running a simulation of unsteady airflow around aircraft landing gear. Rescale’s web browser-based simulation platform was used to set up and submit the job, and Rescale also provisioned the required computing capacity directly from its hardware partners. The software code of choice was Gerris, an open-source program used for the solution of partial differential equations describing fluid flow.
