The purpose of this study is to validate STAR-CCM+ accuracy in aeroelastic applications. The benchmark examined here is from the Aeroelastic Prediction Workshop. The High Reynolds Number Aerostructural Dynamics (HIRENASD) wing is chosen for this verification study as a good distribution of unsteady pressure measurements, deflection measurements and balance loads measurements at transonic conditions with realistic flight Reynolds numbers. The CFD geometry has been combined from IGES files and the CGNS mesh obtained from HIRENASD website. Based on this geometry, a polyhedral mesh has been...
A Surface Effect Ship (SES) has a pair of side hulls with flexible seals fore and aft which contain the cushion pressure provided by lift fans. Due to the highly flexible nature of these seals, they interact quite dynamically with the free surface. A series of model tests were performed at the University of Michigan in order to aid the understanding of this interaction and these tests are being simulated in this presentation. This simulation employs the co-simulation engine coupling Abaqus with STAR-CCM+ first implemented in version 5.06. Early versions of this tool used explicit (loose)...
Fluid-elastic instabilities of a flexible rod bundle in turbulent water cross flow have been well studied in laboratory scale experiments. As a validation, unsteady RANS simulation in STAR-CCM+ are coupled to Abaqus via co-simulation and the results compared to experiments. Because of the strong rod-water coupling, this validation represents a complex test for implicit coupling technique realized in STAR-CCM+. STAR-CCM+ and Abaqus models were constructed based on the description and dimensions provided in the reference documentation.* The rod fastening conditions and properties were tuned to...
The capabilities of Battery Design Studio are presented in the context of battery design challenges facing battery developer and users. Examples ranging from cell design to model selection and parameterization are used for demonstrating how to design cells for automotive applications. Finally, new features in planning are discussed.
First, the computational activities for the thermal management of electronic devices in the development process of a passenger car are presented. The numerical challenges related to the temperature computation of a refrigerant cooled battery and related to its temperature control are reviewed. In this respect, a conjugate heat transfer model has been created in STAR-CCM+. The comparison with experimental results shows a good agreement for the temperature of the cell can. The battery temperature is computed in transient conditions under vehicle electrical and thermal loads. Finally, the effect...
The increasing use of electric drive systems in many transportation devices, whether automobiles, trains or planes, has added a new demand on simulation methods. This trend, coupled with the ever increasing demands on power density and reduced package size, has forced more complex physics into such simulation technology. This presentation will cover CD-adapco's approach to provide engineers with highly accurate tools to simulate these new phenomena and hint at some newer developments.
This presentation illustrates a new application of the previously developed 1D transient DARS Catalyst model for the simulation of a Selective Catalytic Reduction (SCR) catalyst. Initially demonstrated for NOx-Storage Catalyst (NSC), the DARS Catalyst model uses a single-channel or a set of representative channels for the simulation. This model is fully valid and employed further for the SCR catalyst. Each channel is discretized into a number of cells. Each cell is treated as a Perfectly Stirred Reactor (PSR) with a thin film layer for washcoat treatment. Three global parameters are used to...
Counterflow burners consist of steady, axisymmetric, laminar flows of two counterflowing reactant streams toward a stagnation plane. These burners can be used to experimentally study and develop detailed chemical mechanisms of combustion under a wide range of conditions. Global flame parameters such as the critical limits of extinction and autoignition, as well as flame structure, including flame temperatures and species concentrations can be measured and tested against established reaction mechanisms using 1D numerical model with known conditions at the duct exits. This presentation is a...
We have been expanding our application coverage for reacting flows that require coupling of different processes with a wide-range of length and time scales. We capture these interactions by using a combination of online as well as offline computations that enables us to perform advanced reacting flow calculations incorporating finite-rate chemistry while keeping the computational time manageable. Our models have been extended to work in multi-phase as well as with segregated and coupled flow solvers. Examples from chemical process and combustion applications will be shown that will include...
