Analysis-Led Design in Subsea Engineering
This webcast illustrates the effectiveness of analysis-led design methods in the up-front engineering phase. Presenters discuss the use of sophisticated modeling and simulation techniques for the verification of design concepts. These methods have become essential as production operators and service providers operate and design subsea equipment for High Pressure/High Temperature (HP/HT) wells, and for field equipment that may reach seawater depths approaching 10,000 feet. In addition, presenters discuss incorporating the use of modeling and simulation software to ensure during the design...
The inter-phase momentum transfer between gas and solid phase is accounted for by the drag force. Several researchers have proposed correlations for modeling drag for gas - particle flows. In this report, we will be focusing on the steps needed to tune the Syamlal O’Brien drag law.
Prometheus (which literally means "forethought"), was a Titan whom Zeus had defeated. He was given a task to go to earth and make its creatures. He crafted human beings and gave them arts and culture. But they were suffering and terribly shivering in the cold. So against Zeus’ direct wishes, he also gave “fire“ to mankind. Little did humans know that this gift meant literally they would have to “play with fire”. In order to have control over the the wild rage, as wise as they were, humans started to investigate it in more scientific ways. But they found it wasn’t very easy. In fact it was so complicated, even schoolbook combustion examples would have stiff and difficult to solve ODE systems…
CD-adapco, the largest privately held CFD-focused provider of Computer Aided Engineering software, today announced the release of DARS v2.10. DARS is a standalone simulation tool for the 0D and 1D management and analyses of chemical reactions. DARS v2.10, which is available on the Steve Portal, now features a library generation functionality that makes it possible for customers to quickly explore new fuel blends and operating conditions for simulations with STAR-CD® and STAR-CCM+®.
The release of DARS v2.10 makes customers more competitive through the software’s enhanced capabilities in the areas of technology , experience and productivity . Technology DARS v2.10 provides a new library generation functionality which facilitates analysis of fuel compositions, accurate prediction of knock and emissions for dual fuel engines, exploration of combustion of any fuel or oxidant mixtures and exploration of soot yield for new fuels and new operating conditions. The technological gains in DARS v2.10 provide customers with confidence in their results through new modeling...
Industrial flames contain 1,000s of species interacting through 10,000s of reactions. Resolving the flame using a detailed CFD grid with full chemistry and including proper turbulence-chemistry interaction is extremely CPU intensive. DARS makes it possible to pre-tabulate the chemistry to enable efficient simulations.
Perforated Plates and Other Porous Media: To Idelchik or not Idelchik
Electronics assemblies frequently include perforated plates, louvers, fibrous filters, finger guards and other components with very fine flow passages. The primary purpose of each of these parts might serve aesthetic purposes, provide EMI shielding, dust filtering or ensure user safety, but they also can significantly restrict the air flow through the system. Properly accounting for the added flow resistance they introduce is critical for the thermal design of the electronics. But because these porous media have fine geometric features with small flow passages, it may not be desired — or even...
DARS Basic is GUI-driven and provides a library generation functionality which facilitates analysis of fuel compositions, accurate prediction of knock and emissions for dual fuel engines, exploration of combustion of any fuel or oxidant mixtures and exploration of soot yield for new fuels and new operating conditions.
Using DARS, the product design cycle will be faster and more cost-effective through the prediction and analysis of chemical processes and emission formation before, or as a complement to, experimental testing
