Improving Operations: Coupling DEM and CFD to Optimize Particulate Flows
To produce products at the lowest possible cost and high quality while meeting safety requirements, companies in the chemical and mineral processing industries must optimize all elements of their operations to stay competitive. Handling equipment such as pneumatic conveyors, hoppers, chutes and belt conveyors is used for the transport of particles. Processing equipment such as cyclone separators, calciners, dryers and coaters are used for various unit operations. Process engineers need to take into consideration not only the flow of particles but also that of a carrier fluid. The intricate...

Hybrid Multiphase Modeling: Discover the secret of covering multiple regimes in a single simulation Traditional multiphase flow models such as the Volume of Fluid method (VOF) and Eulerian Multiphase (EMP) embed assumptions about the nature of the flow being modeled, limiting their applicability to a single regime (type of interaction). Real-world applications often contain more than one regime, spray or foam forming next to a free surface, or a component being coated with a film when being taken out of a bath of liquid. These applications traditionally had to be modeled with multiphase...
Neben dem Erhalt immer besserer Energielabels und dem damit einhergehenden Gewährleisten strikterer Effizienzkriterien stehen im Haushaltsgerätemarkt und bei seinen Produkten heutzutage vor allem das Erfüllen gesteigerter Endverbrauchererwartungen und Sicherheitsaspekte im besonderen Fokus. So ist für die Hersteller beim Design und der Entwicklung von Öfen, Kühlschränken, Waschmaschinen und Trockner nicht nur ein möglichst detailliertes Verständnis von dem thermischen Verhalten der Geräte erforderlich, um energieeffizientere Produkte entwickeln zu können, auch die korrekte Funktionsweise und...
In the early hours of Saturday May 6, at the Monza motor racing circuit in Italy, Eliud Kipchoge ran 26.2 miles in 2 hours and 25 seconds, beating the existing marathon world record by 2 minutes and 32 seconds. The run was the culmination of Nike’s “Breaking 2” project, a two year program aimed at demonstrating that it is physically possible for a human to run a marathon in less than two hours. Before the run, much of the publicity had focused on Nike’s spring loaded Vaporfly Elite running shoe, which they had claimed improves running efficiency by as much as 4%. However in the days afterwards much of the conversation turned to aerodynamics, and the influence of the unfeasibly large timing board that was mounted on top of the pace car that drove in front of Kipchoge, and the “delta formation” adopted by his team of “relaying” pacers. By some calculations drafting was responsible for about 1:30 of the 2:32 that Kipchoge knocked off Kimetto’s world record. In order to determine just how much influence "aerodynamic trickery" had in getting Kipchoge within 26 seconds of the mythical 2 hour barrier, we decided to run a series of computational fluid dynamics simulations using STAR-CCM+,
Driving innovation with gas & liquid-fuel combustors through CFD and design exploration
Until recently, the ability to accurately characterize combustion of gas-fuels (usually methane) and liquid-fuels required the use of expensive testing and validation. The development of computational methods over the last 20 years has opened the doors to new methods to help engineers discover better combustor designs faster by enabling the accurate assessment of such important combustor performance characteristics as: Fuel/air mixing The ability to use different fuels in the same combustor (or with only slight modifications) Predictions of NOx and CO emissions and soot formation, including...
Ensuring safety during production and maintenance is critical to the oil and gas industry, while operational reliability and production assurance are key to operating a successful oil and gas production facility. This event will explore the role of simulation in two aspects of oil and gas, maintenance and production operations. We will have two presentations: Simulation Engineering: A Virtual Blow-Out Preventer Alistair Gill, Vice President (Advanced Engineering) Wild Well Control, will present how his team uses simulation of pipe freezing to assess how to perform safe mechanical repairs to...
Growing competition and increasing environmental awareness within the marine industry drives a continuous need for more efficient methods for the design of new vessels. Today, CFD is widely used to perform analyses of ship hulls in calm water, yielding results which can be used to quantify important parameters such as calm water resistance or propeller-hull interaction. However, calm water is usually far from the true operating conditions, meaning that understanding the performance in real sea states is of great importance. In many cases, the optimum design for rough seas differs...
Please join us on June 6 for an introduction to STAR-ICE, the exciting new add-on to STAR-CCM+ ® for setting up in-cylinder simulations. Due for first release in STAR-CCM+ v12.06, STAR-ICE represents the transition of modeling your in-cylinder simulations from STAR-CD, allowing you to leverage the many powerful benefits of the STAR-CCM+ platform. This exciting early look at the add-on will inform and prepare you for the impressive next chapter of in-cylinder CFD. In this webinar, we will be covering the following topics: What is STAR-ICE? Transitioning from STAR-CD to STAR-ICE The STAR-ICE...
Improving semiconductor shower head performance with simulation
The shower head is a critical part of a chemical vapour deposition (CVD) chamber, distributing gases properly to ensure uniformity of deposition rates across the wafer. The shower head typically consists of a large number of small holes through which the gas is delivered over the surface of the wafer. Precise control of flow speed, temperature and gas species distribution is critical, so a well-designed shower head provides higher quality deposition as well as increased wafer throughput. This On-Demand webinar will explore the usage of simulation to improve the design of a shower head. The...
