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...
Digital Simulation for Verification & Validation of Medical Products
This is a short video delivered by James B. (Jim) Thompson, Ph.D. from Siemens PLM Software. Jim has worked in the Product Lifecycle Management (PLM) industry for 30 years. Initially in R&D roles for development of CAD/CAM and PLM software, and then as a leader responsible for technology consulting with customers in a variety of industries. Since 2006, Jim has focused exclusively on the Medical Device and Pharmaceutical industries. At Siemens PLM Software, Jim is currently responsible for Siemens PLM’s global business strategy for the Medical Device and Pharmaceutical industries. James B...

Designing the Next Generation of Supersonic Business Jets with Low to No Sonic Boom
Spike Aerospace is developing the Spike S-512 Supersonic Jet, a state-of-the art aircraft that promises to cut flight times in half , through the use of CD-adapco’s industry-leading computer aided engineering software tool. The goal of this development is to leverage computational methods to design a Mach 1.6 business jet with less than 70 PLdB, allowing the Spike S-512 to fly over land. Viewing this webcast you will earn how leading simulation software is being used to study the preliminary aerodynamics of the S-512 design. Additionally, you will learn how leading companies such as Spike...
Better Designs Faster with Integrated Fluid-Structure Interaction (FSI)
From an aircraft wing flexing in flight, a ship propeller deforming in rough seas, or a tank stressed by sloshing liquid, fluids and structures are in concert all around us in the physical world. And although Fluid-Structure Interaction (FSI) plays an important role in how structures behave in the real world, within the engineering simulation world these two disciplines are largely still treated independently. However, new FSI technology is finally helping to bridge the gap between fluids and structures in many leading companies. Engineers can now tackle FSI problems using an integrated...
