Siemens PLM Software releases STAR-CCM+ v11.06, provides engineers with significant gains in technology, customer experience and productivity. New York and London. October 26, 2016 Siemens PLM Software , a leading global provider of product lifecycle management (PLM) and manufacturing operations management (MOM) software, announced today the latest release of STAR-CCM+ ® software, version 11.06. This latest version of the industry-leading engineering software tool allows engineers to discover better designs, faster and aligns with Siemens’ Smart Innovation Portfolio that helps manufacturers...
A well ordered workshop – is it inherently capable of making us more productive? Is it really worth the effort to get organized? Steve Jobs offered the following thought: “That's been one of my mantras - focus and simplicity. Simple can be harder than complex: You have to work hard to get your thinking clean to make it simple. But it's worth it in the end because once you get there, you can move mountains.”
When you spend as much time in an airplane as I do, you learn to appreciate the performance of the environmental control system (ECS). Modern ESC systems are marvels of engineering with complex mechanisms to control pressure, temperature, humidity and air quality to ensure a comfortable environment for hundreds of passengers. In spite of the significant investment airframers have made over the years, customers are looking for a more comfortable ride. With more and more entries into the regional jet market, airframers are looking for ways to differentiate their planes by providing an upgraded customer experience.
A well organized workshop, purposely conceived to build and revise things of interest, is truly appealing with its array of tools, carefully ordered, in a familiar and comfortable environment. Now you’ve probably heard the expression “Use the right tool for the right job.” That works when you know what tools you have in your workshop, what they are supposed to do and exactly where you can find them. With the STAR-CCM+® v11.06 release, we’re adding and upgrading tools that will improve your ability to productively build and revise your simulations. You’ll be able to set up your simulations more comprehensively and consistently with a reduced likelihood of errors. And you’ll be able to more efficiently conduct critical reviews in the deeper details of your simulations with your colleagues and your customers. In part one of this blog, I’ll be talking about Simulation Parameters and Global Tagging.
In an increasingly competitive automotive market, customers demand a comfortable cabin environment for their vehicle. At the same time a combination of consumer demand and fuel and emission targets require that this cabin environment be delivered in the most energy-efficient way. Balancing these requirements represents a difficult engineering challenge.
It is no secret that the oil and gas industry has been experiencing some extremely difficult times over the last few years. During this market downturn that has seen barrel prices plummet, more oil and gas companies are finding that simulation is a viable solution. In fact, simulation is one of the more important tools oil and gas companies can use to trim costs and save money.
The efforts to improve the process efficiency of modern gas turbines usually lead to competing objectives for the design of the cooling system as turbine inlet temperatures are continuously increased. Typically, the designer of modern cooling systems is confronted with the requirement to achieve a wall temperature below the maximum allowable wall temperature which is fixed by the material and life span requirements. Simultaneously, a homogenous temperature distribution is desired in order to reduce thermal stresses due to temperature gradients. To maximize cycle efficiency, all this should be...
In modern gas turbines, the film cooling technology is essential for the protection of hot parts. Today, shaped holes are widely used, but besides others, the NEKOMIMI-shaped cooling holes have shown that there is still potential to increase the film cooling effectiveness significantly by generation of Anti-Counter-Rotating Vortices (ACRV). As a result, the cooling air remains close to the wall and spreads in lateral direction along the surface. The ACRV result from the specialized shape of the expanding hole exits (NEKOMIMI-shape). Thus, the design parameters have a crucial impact to the...
As any connoisseur of champagne or beer knows, not all bubbles are the same. Creamy champagne and gassy stout have never caught on, although the former sounds vaguely appealing! The same goes for droplets for that matter – nobody likes a shower that produces a fine mist rather than an invigorating spray. These examples are an indication that the nature of a fluid is dramatically changed by the size of the droplets or bubbles contained within it.
Increasing CFD Simulation Throughput for Real, Complete Pump Systems
Pump companies use CFD flow simulations to achieve different goals – for instance, to troubleshoot poor performance of existing pumps , to validate the performance of already-defined designs , or to predictively explore the performance associated with new design concepts . But most pump engineers agree that the ultimate goal is to perform more simulations in order to discover better pump designs, faster as a substitute for slower and more expensive physical prototyping and testing. Moreover, it is possible for CFD simulation to be used to predict pump performance under wide-ranging operating...
