This solution brief reports on a study that used multiphysics simulation and optimization technology to explore drill-bit design. The overarching objective was to reduce costs by improving drilling process efficiency. The exploration project team used STAR-CCM+® software for multiphysics simulation and the built-in Optimate+ software optimization solution from product lifecycle management (PLM) specialist Siemens PLM Software.
Pipeline and piping vibration can cause a range of issues from reduced process efficiency and unplanned shutdowns to decreased equipment life or even loss of containment. It is an issue for engineers designing systems in many industries and has been of specific concern in subsea oil and gas in recent years. This article focuses on the phenomenon termed flow-induced vibration (FIV), where the internal flow of process fluids within a pipeline or piping system causes some form of vibration of the pipe.
Erosion caused by solid particles in process flows impacting on the surfaces of downhole equipment or pipe walls is a common cause of damage and wear in oil and gas production as well as many other process industries. In the oil and gas industry, erosion can pose a significant integrity risk in flowlines, valves and connectors in production systems if not managed appropriately. Computational fluid dynamics (CFD) is a cost-effective means of predicting the location and magnitude of erosion damage. In practice, different flow regimes and particle loadings can lead to a range of erosion...
Enhancing confidence in design decisions by utilising the new postprocessing features in STAR-CCM+ v12
Drones and VTOL (Vertical Take-off and Landing) systems, unlike their fixed-wing counterparts, are extremely versatile in application and operate in highly complex, unsteady environments. The design of such systems has to account for and balance a multitude of physics – fuselage/ rotor aerodynamics, aeroelastic and aerothermal effects, noise and vibration, icing, engine integration, fuselage-rotor aerodynamic interaction, transonic and compressibility effects and many more. Recent advances in automated mesh generation, the availability of high-fidelity and fully-coupled physics, and increased...
Improving the Efficiency of Hydro Turbines with 3D CFD
In just about every part of the world, hydro power offers a reliable source for contributing clean and renewable energy to the electricity grid, helping to reduce greenhouse gas emissions. Moreover, sources such as the recent Hydropower Vision report from the U.S. Department of Energy (DOE) predict that significant capacity can be obtained from multiple sources. Further, when assessing the relative influence of specific variables on the potential for hydropower growth, the No. 1 factor listed among those exerting the greatest influence was “ technology innovation” (in order to increase...

Almost everyone appreciates the beautiful (and often sleek) styling of a new automobile model. However, the smooth curves of a new car model are as much to do with aerodynamic necessity as aesthetic pleasure. A typical sedan cruising on the freeway will use about 18 percent of its fuel energy in overcoming aerodynamic drag*. Since the power required to overcome drag rises with the cube of velocity, the faster you go, the more fuel you use. (If this seems deceptively low, it’s because the process of turning gasoline into the kinetic energy of the vehicle is tremendously inefficient, thanks to the second law of thermodynamics and the fact that entropy sucks). In order to maximize the driving range of a vehicle, it’s generally a good idea to minimize its drag (and therefore fuel consumption). This is a particular concern for drivers of electric vehicles, whose range is limited by a fixed battery capacity.
Growing up in the countryside in Sweden, I got used to several power outages a year due to snow, storms, lightning, etc. No water, no electricity and no heat for days, sometimes in the middle of winter, meant you had to huddle together to keep warm, get water from a local supply and eat cold food. A possible remedy for this annoyance is distributed energy generation. Solid Oxide Fuel Cell (SOFC) combined heat and power systems are independent of local weather conditions (unlike wind and solar systems) and provide a cleaner, quieter and more efficient alternative to traditional petrol generators. SOFC systems are used to power and heat/cool data centers, homes and stores across the globe, as well as for offshore and remote military applications. Power outage for a data center doesn’t only mean inconvenience and freezing indoor climate, it also means large financial losses due to downtime, so SOFC systems are often used to supply reliable power. To support the movement towards cleaner and more efficient distributed energy we have made simulations of SOFC systems straightforward in STAR-CCM+® v12.02. You can now natively specify the required electrochemical reactions on the anode and cathode as well as the ion transported through the membrane, making it much easier than before to set up such calculations.
