Manufacturing Simulation for the Casting Industry with STAR-Cast
In manufacturing and product design, CFD is deployed for the design, validation, evaluation and optimization of the production process. The casting industry has adopted simulation to help with challenging castings, such as, to name just a few: designing the gating and the mold, minimizing necessary super heat, and finding the optimum pouring curve to reduce gas entrainment. It is with the aim of providing solutions for this whole range of casting applications that STAR-Cast was developed. With version 8.02, we will reveal a brand new STAR-Cast, now completely embedded within STAR-CCM+. STAR-...
Technology Review: Modeling & Simulation for Biomedical Device Design
Biomedical device design is facing increasing product complexity while prototype building and testing can take months. The inherent risk in new medical product development can be mitigated through a deeper understanding of the design properties and functions achieved through modeling and simulation. Modeling capabilities for the design of various devices from respiratory (inhalers), pacemakers, MIT/CT scanners, to cardiovascular and microfluidic devices will be discussed. The importance of Fluid Structure Interaction (FSI) modeling will also be addressed. The implicit coupling of STAR-CCM+...
Trends, Implications & Electronics Thermal Design Needs due to System Electrification
For many years we have seen increased computing capability via more powerful microprocessors in higher numbers in products; nearly all of our daily tasks involve some type of computing device. The electronics in these devices typically involve information processing, delivery and systems controls. More recently electrical power has been increasingly used for the primary drive functions of much larger systems. This electrification has accelerated in industries including automotive, aerospace and marine. Temperature is the key design constraint for both computing and power electronics even with...
Engine Assembly Thermal Simulation using the Cycle Average Tool
Modeling boundary conditions for thermal simulation of internal combustion engines entails convection heat transfer from the combustion flow path, crank case and head top oil combined with conduction heat transfer from sliding contact and friction between the piston assemblies, liners, valves, guides and intermittent contact of the seats. The time scale for an engine thermal analysis is much greater than the time for one engine cycle. Therefore, it is helpful to average the heat transfer characteristics for surfaces which see sliding contact mixed with convection states over one engine cycle...
Advanced Turbomachinery Simulation using STAR-CCM+
STAR-CCM+ provides a unique set of simulation capabilities, which allow for accurate and rapid simulation of turbomachines. These simulation capabilities include conjugate heat transfer analysis, aeroelastic analysis and performance mapping. This presentation will discuss modeling capabilities critical for the industry such as geometry handling, conformal meshing of complex bodies, solution methods and advanced post-processing. Details of how the Harmonic Balance Solver within STAR-CCM+ can be used to perform aeroelastic analysis will be presented. Additionally, case studies will be used to...
The Effects of the Planform Shape on Drag Polar Curves of Wings: FSI Analysis Results
This presentation discusses the preliminary results obtained from the aeroelastic analyses of two half-wing models, with a curved and a swept planform. This work was carried out by the Aerospace Section of the Department of Civil and Industrial Engineering of Pisa University. As demonstrated in previous papers on the topic of rigid models of wings, the curved planform causes a variable angle of sweep along the wing span, resulting in a greatly reduced wave drag at transonic flight conditions. The present numerical comparisons between a curved and traditional swept wing (with the same aspect...
Aeroelastic Workshop: The Validation of Aeroelastic Simulations using STAR-CCM+ coupled to Abaqus
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...
Fluid-Structure Interaction of a Surface Effect Ship Bow Seal & a Free Surface
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)...
The Validation of Fluid-Elastic Instabilities in a Flexible Rod Bundle using STAR-CCM+ coupled to Abaqus
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...
