Optimization of a Pump-Turbine Runner
Posted Thursday December 8 at 5:2am
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.

Selecting an Appropriate Turbulence Model
Posted Tuesday November 29 at 12:5pm
Engineering.com has published a concise article on the various turbulence models available in commercial CFD software packages. The article lists the various models in use, their theoretical basis, advantages, and disadvantages.
Various empiric or semi-derived turbulence models have been created to help engineers to find the best model to fit their system of study, but this process could take a lot of trial, error and physical testing.
How to Add CFD Into a Fluid Mechanics Course
Posted Tuesday November 29 at 10:24am
Siemens PLM Software will host How to Add CFD Into a Fluid Mechanics Course on December 13th.
Faculty often want to add computational fluid dynamics (CFD) into their Fluid Mechanics courses, but don’t know how to make it fit into their already crowded syllabus. In addition, CFD class projects are sometimes limited due to learning curve challenges that involve the creation of geometries and meshing. Are there better ways to teach CFD techniques, especially to undergraduates?
