CFD Simulation Contributes to New Heart Health Metric
Posted Fri February 03, 2017 @05:20PM
Print version Email story Tweet story
Application The heart is a wonder of design – a pump that can function for 80 years, and billions of heartbeats, without breaking down. But when it does malfunction, the results can be dire.

In research reported in the International Journal of Cardiology this month, scientists from Johns Hopkins University and Ohio State University presented a new method for predicting those most at risk for thrombus, or blood clots, in the heart.

Aerodynamic Design of Small Chiller Compressor for Domestic CHP Applications
Posted Wed February 01, 2017 @07:44AM
Print version Email story Tweet story
Application A leading manufacturer of high speed rotating machines, asked Advanced Design Technology to carry out the complete aerodynamic design of a brand new centrifugal chiller compressor stage using the inverse design approach available through the TURBOdesign Suite software.

Performance targets (Pressure Ratios and Efficiencies) and operating points were set by the customer before the start of the project. Tight requirements on off-design and mechanical performance and the overall size of the stage were also set by the customer.

Increasing Mixing in Microchannels using Design Optimization
Posted Fri January 20, 2017 @05:03PM
Print version Email story Tweet story
Application The latest blog post from Flow Science discusses optimizing microchannel geometry using the design optimization software, CAESES®, from Friendship Systems GmbH.

Mixing fluids can be very important in the design of miniaturized chemical and biochemical analysis systems. However, the mixing of fluids at the micro-scale is challenging because of an inherent lack of any mechanism to induce the mixing.

Application Cost reduction is a driving force in pump design. The manufacturing cost of centrifugal and mixed pumps generally varies with the volume of the pump. To reduce manufacturing costs, the pump diameter must be reduced for a given head which results in an increase in head coefficient.

Application Mixing different fluids with potentially different properties remains one of the most important and potentially costly industrial processes. In this Flow Science article, we complete our presentation of the newly-redesigned particle model in FLOW-3D v11.2 and take a fresh look into one of the most common and essential industrial processes: mixing.

Optimization of a Pump-Turbine Runner
Posted Thu December 08, 2016 @05:02AM
Print version Email story Tweet story
Application Pumped hydro energy storage (PHES) is currently the only proven large-scale (>100 MW) energy storage technology. The benefits of PHES on electrical system operations are well documented in textbooks and journals. The flexible generation of PHES can provide upregulation and downregulation in power systems. Furthermore, the quick start capabilities of PHES make it suitable for black starts and for the provision of spinning and standing reserves.
