An overview is presented of key methodologies in STAR-CCM+ and STAR-CD for simulating disperse multiphase flows involving droplets, solid particles and/or liquid films, including: atomisation; particle dynamics and heat/mass transfer; wall impact and erosion; and liquid film dynamics, heat/mass transfer and melting/solidification. Examples are shown of validation studies and applications in the aerospace, automotive, oil/gas and manufacturing and medical fields.
Multiphase and reacting flow simulation capabilities of STAR-CCM+ is increasing with every release. This makes it possible to solve advanced level problems in the chemical processing industry. Some of the largest chemical companies around the world use STAR-CCM+ for addressing challenging day to day problems. A few pertinent enhancements from this year will be reviewed. Then some recent validation and case studies in gas-liquid flow, fixed bed reactor modeling and heater design optimization will be presented.
New capabilities in modeling multiphase flows using the Eulerian Multiphase (EMP) model are demonstrated by examples. These new capabilities include granular model for multi-size particle flows, RSM for turbulent multiphase flows, multi-component boiling model for evaporation of chemical species and the Adaptive-MUSIG (A-MUSIG) population balance model for poly-dispersed flows.
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...
STAR-CCM+ is widely used in the global aerospace and defense industries due to its advanced capabilities in the field of numerical simulation as part of the overall CAE process. This presentation will highlight some specific modeling capabilities in relation to various engineering application areas in the aerospace and defense industry and discuss how simulation tools are evolving rapidly to meet the most demanding engineering requirements.
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...
The evolution of nuclear reactor design is being greatly influenced by the availability of new, versatile next-generation tools. The adoption of the new analysis and simulation techniques is pushing the operational limits of reactors and fuel, with large impact on the economics of the plants, while simultaneously improving the safety standards. One of the most recent and important developments has been the adoption and adaptation of computational fluid dynamics (CFD). Used alone or in combination with neutronics, structural, material performance and system analysis tools, the analysis...
Heat Transfer with STAR-CCM+ including Conjugate Heat Transfer (CHT) will be discussed. CHT Examples will be presented for several automotive applications.
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...
