STAR-CCM+ is considered the market leader for simulation of flow and motion of floating bodies within marine and offshore industry. In this presentation examples of applications by customers are used to highlight the individual features of STAR-CCM+ and to prove the benefits of simulation. This is followed by presenting the new features that are currently under development and targeting specific marine and offshore applications e.g. extensions of motion modeling to allow various combinations of prescribed and free motion (like PMM-tests), extension of cavitation model, internal wave...
CD-adapco has been involved with simulation in the ground transportation industry for nearly a third of a century. Initially, simulation was used as a tool to investigate the cause of a failure. Models were fairly simple that looked at a specific feature of the design, for example, coolant flow through an engine, and used simulation to bring the coolant flow to the critical parts of the engine that were failing. Today, simulation is much more mature, allowing engineers to simulate various real-world tasks of a system of components. It is no longer just bring the coolant flow to critical part...
Accurate and efficient simulation of rotating machinery is critical to many industries including energy, aerospace, automotive and healthcare. Each of these application areas presents unique challenges and simulation objectives. Turbomachinery specific capabilities within STAR-CCM+ allow users to model rotating systems with unparalleled accuracy and efficiency. These unique capabilities along with simulation recommendations and guidelines will be discussed using examples from a variety of industries. Examples will include the multi-objective optimization of a fan, unsteady analysis of a gas...
STAR-CCM+ has been providing a high level multiphase model with melting/solidification capabilities which contain appropriate viscosity models to account for the influence of the solidification on the melt flow, and allows defect prediction such as air entrainment and misruns. In addition, add-on module STAR-Cast contains material database for various kinds of alloys and shell generation tool for investment casting and it provides high-fidelity casting simulation toolset to model a series of casting processes. Some of examples will be introduced with demonstration.
Granular materials are of critical importance in many industrial processes. We make use of STAR-CCM+ DEM model for granular material’s behavioral analysis as well as for solving engineering problems. In this report the results of a channel blockage simulation of granular flow in a pipe is discussed. We found good consistency between the simulations and the data in our hands.
During the last two decades, combustion models and application for internal combustion engine was mainly developed using a single component fuel. When the situation allows it, this component could be a pure substance like a pure iso-octane or a representative single component for blended fuels. In theory, the single component should represent all the physical and chemical properties of the blended fuel. Although this approach appears relatively rough it has successfully applied to engine application. Recent regulation to reduce fuel consumption and emission, the use of bio-fuel (presence of...
Presentation includes the overview of DEM capabilities in STAR-CCM+ and examples with analysis of DEM and DEM coupled to CFD simulations for Chemical Processing Industry.
A flash boiling phenomenon differs from the normal evaporation (isobaric heating) and where a rapid evaporation occurs due to rapid pressure drop under saturation pressure condition. This report explains the physical process of flash boiling phenomenon for single component fuel and further describes the evaporation enhancement effect when multicomponent fuel is applied. The fuel for normal engines is multicomponent fuel and when mixing fuel components, which have largely different boiling temperatures, two phases region is formed on the pressure-temperature diagram. This allows evaporation...
The evolution of nuclear reactor design is being greatly influenced by the availability of new, versatile next-generation tools. Multi-physics analysis of nuclear reactor systems is pushing the operational limits of reactors and fuel, with large impact on the economics of the plants, while simultaneously improving the safety standards. Computational Fluid Dynamics, used in combination with neutronics, structural, material performance and system analysis tools, has enabled nuclear operators and vendors to greatly enhance the capacity and availability of current reactors. The increased adoption...
We have been expanding our application coverage for reacting flows that requires coupling of chemistry and flow physics that span a wide-range of length and time scales. We capture these interactions by using a combination of online as well as offline computation using our chemistry tool called DARS to incorporate finite-rate chemistry effects while keeping the computational cost manageable. These models have been extended to work in multi-phase as well as with high-speed flows. Examples from chemical process and combustion applications will be shown that will include surface reactions, multi...
