Flow Science is a leading provider of computational fluid dynamics solutions. Flow Science's flagship CFD software, FLOW-3D, provides a powerful tool for complex fluid modeling problems. FLOW-3D enables highly accurate simulations of free-surface flows using TruVOF, the original and true form of the Volume-of-Fluid technique.
FLOW-3D/MP enables modelers to take advantage of high-performance computing clusters to tackle problems featuring large domains or long runtimes, delivering shorter design cycles and an opportunity to do comprehensive parametric studies within design cycles. All this can be achieved while retaining the accuracy offered by FLOW-3D.
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. Three case studies are presented in this article 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.
Laser-powder bed fusion additive manufacturing involves complex physical processes. Particularly, the absorbed laser beam energy melts the particles and forms a molten pool where a strong fluid flow occurs driven primarily by surface tension gradient. The heat transfer and fluid flow are significantly affected by local arrangement of powder particles in the powder bed that can vary from location to location. Because of the highly transient fluid flow, the shape of the molten pool surface is constantly evolving, affecting the final surface quality.
