The Effect of Turbulence Modeling on Dynamic Urban Wind Simulation
Posted Wed March 15, 2017 @03:02PM
Print version Email story Tweet story
Application Rheologic has posted a case study on the effects of turbulence modeling on dynamic urban wind simulation.

Wind in urban environments impacts on a number of issues from local microclimate, to energy use for heating and cooling, facility performance (HVAC), rents (arcades, outdoor dining areas) and in the future possibly UAV delivery routes. While steady-state simulations that cover the average wind velocity are very helpful, looking at the dynamic behaviour can sometimes be critical.

Print version Email story Tweet story
Application Grundfos are one of the world’s leading pump manufacturers for circulators, heating and air-conditioning as well as other centrifugal pumps. They have been a pioneer in utilizing computer aided engineering (CAE) in their design, development and manufacturing process for pumps and motors.

Grundfos have been using an integrated CAE and design system with ANSYS/CFX for structural and fluid flow analysis and TURBOdesign1 for hydrodynamic design.

Application by Faizal Yusuf, M.A.Sc., P.Eng.
Specialist Engineer in the Hydrotechnical Department at BC Hydro

BC Hydro, a public electric utility in British Columbia, uses FLOW-3D to investigate complex hydraulics issues at several existing dams and to assist in the design and optimization of proposed facilities.

Faizal Yusuf, M.A.Sc., P.Eng., Specialist Engineer in the Hydrotechnical department at BC Hydro, presents three case studies that highlight the application of FLOW-3D to different types of spillways and the importance of reliable prototype or physical hydraulic model data for numerical model calibration.

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.
