| FLOW-3D for Water Resource Recovery Facilities Process Modeling
In addition to presenting on overview of FLOW-3D’s unique range of modeling capabilities in modeling free surface and mixed pressurized flows, this webinar presentation will focus on modeling several key process units that are found in Water Resource Recovery Facilities: • Chlorine tank reactors illustrate hydraulics and chemistry interactions, including bio-kinetic species evolution processes. • Secondary clarifiers and settling tanks demonstrate specialty drift flux and particulate transport features. • Grit removal chambers exemplify a separate class of particulate/hydraulic coupled vortex driven interactions. The webinar will be presented by senior Flow Science CFD modeler John Wendelbo – questions may be addressed to john.wendelbo@flow3d.com. | Oct 6, 2016 | 11:00am MDT | 1 hour | Register |
| HPDC Webinar Series: Part I - Thermal Die Cycling
High pressure die casting (HPDC) simulations are typically quite complex. To accurately model the entire physical process one needs to account for heat transfer, melting and solidification, air entrainment, surface defect tracking and cavitation. We simulate and demonstrate in FLOW-3D Cast the entire HPDC process in this 3-part webinar series. The process based workspace implements the necessary physical models and numerical defaults while setting up the stages of thermal die cycling (TDC), filling, solidification and cooling. Dies are commonly used to produce thousands of castings. Ensuring consistent die temperatures is essential to prevent defects throughout the process of the casting and also to prevent warping in die pieces that can lead to dimensional inaccuracies in the final casting product. Prior to making the castings, thermal die cycling simulations are carried out in order to ensure consistent die temperatures. In the first part of our webinar series, we look at the wall temperatures of the die under the combined effects of die heating, spray cooling, air blow-off and cooling channels. | Oct 20, 2016 | 11:00am MDT | 1 hour | Register |
| HPDC Webinar Series: Part II - Filling
High pressure die casting (HPDC) simulations are typically quite complex. To accurately model the entire physical process one needs to account for heat transfer, melting and solidification, air entrainment, surface defect tracking and cavitation. We simulate and demonstrate in FLOW-3D Cast the entire HPDC process in this three-part webinar series. The process based workspace implements the necessary physical models and numerical defaults while setting up the stages of thermal die cycling (TDC), filling, solidification and cooling. In part II of this series, we explore the filling stage of high pressure die casting. Once the necessary die temperatures are obtained, the next step is to implement a properly designed shot sleeve profile to rapidly push metal into the die. In this stage of the simulation, the molten metal needs to quickly fill the die to prevent premature solidification. At the same time, care should be taken so that the liquid metal front does not fold over itself causing air entrainment that results in internal defects or any potential surface defects formed by oxides. This is one of the more challenging simulations since it entails accurately tracking the metal front at high pressures and speeds. | Nov 15, 2016 | 11:00am MST | 1 hour | Register |
| HPDC Webinar Series: Part III - Cooling and Solidification
High pressure die casting (HPDC) simulations are typically quite complex. To accurately model the entire physical process one needs to account for heat transfer, melting and solidification, air entrainment, surface defect tracking and cavitation. We simulate and demonstrate in FLOW-3D Cast the entire HPDC process in this three-part webinar series. The process based workspace implements the necessary physical models and numerical defaults while setting up the stages of thermal die cycling (TDC), filling, solidification and cooling. In part III of this series, we will explore cooling and solidification in a high pressure die casting. The formation of internal porosity can affect the final quality of the casting part. Once filling is complete, a solidification simulation is performed to track the opening of voids that result in defects. In addition to predicting microporosity and macroporosity, FLOW-3D Cast is also used to investigate a detailed temperature history of the casting part to determine if additional cooling is required, and whether the initial process parameters need to be modified. In the final stage of HPDC, we also look at the thermally induced stresses when the casting part is being cooled after ejection from the die. | Dec 8, 2016 | 11:00am MST | 1 hour | Register |
