What's New in FLOW-3D Version 9.4 This new release of FLOW-3D is packed with useful features and capabilities across the spectrum of industrial applications. The following summary highlights the key new benefits offered in Version 9.4. Contact us to find out how you can purchase or lease the new version of FLOW-3D. New CFD Modeling Capabilities Multi-Sediment Scour and Bedload Transport Model The sediment scour model has been extended to allow the simulation of multiple species of sediment. Among other things, this will allow users to model sands, silts and fine gravel in a single simulation. The addition also includes a bed-load transport model which describes the transport of heavier debris by the currents along the top of the packed bed. Gas mass flux at the core surface. A new core gas model has been introduced in version 9.4. This model describes the generation of gas in sand cores during the pouring and cooling of metal. The gas comes from the decomposition of the sand binder due to the heat coming from the metal. The model is based on first principles and aims at capturing in detail the heat transfer between metal and mold, binder pyrolysis and the flow of gas within the core, and its venting at the core’s external surfaces. The core gas model can be used together with filling and solidification simulations. The model predicts the gas pressure and velocities, and evaluates the mass flux of gas at core prints, at the open surfaces and, most importantly, into the metal. Read more about the Core Gas model in Flow Science Technical Note #84.
