In this study, simulations are carried out using the Euler-Euler granular model in STAR-CCM+ for a gas-solid flow in a rectangular bubbling fluidized bed. The problem studied was announced as Small Scale Challenge Problem (SSCP-I) in 2013. Experiments for this problem were conducted by The Department of Energy's (DOE) National Energy Technology Laboratory (NETL). The objective of this numerical study is to evaluate the reliability of the kinetic theory based granular model (KTGF) in predicting the hydrodynamics of gas-solid flows. The experimental measurements of the bubbling fluidized bed...
Flipping the Classroom: Strategies for Success in Engineering
Universities are increasingly using the flipped classroom model as an alternative method of teaching. How do methodologies of the flipped model approach benefit engineering students, and what examples are being utilized in engineering companies? Furthermore, how are professors employing these techniques today? In this webcast, Professor Ron Averill discusses examples of the flipped model used at Michigan State University and will explore different teaching approaches. The advantages of lifelong learning and relevant learning tools that can prepare engineers for the transition to industry will...
There is increasing recognition of the influence of the flow field on the physiology of blood vessels and their development of pathology. Preliminary work is reported on a novel non-invasive technique, microbubble void imaging, which is based on ultrasound and controlled destruction of microbubble contrast agents, permitting flow visualisation and quantification of flow-induced mixing in large vessels. The generation of microbubble voids can be controlled both spatially and temporally using ultrasound parameters within the safety limits. Three different model vessel geometries—straight,...

Using CFD to Support the Design and Operation of Offshore Vessels
If you are involved in the design or operation of offshore vessels and are interested in learning how industry leaders such as Heerema Marine Contractors (HMC) are using CFD as part of the Naval Architect’s toolkit, this webinar is for you. Designing and operating offshore vessels can be a challenge, making an accurate understanding of vessel behavior an economic and safety necessity. While potential flow codes and model tests remain key parts of the Naval Architect’s toolkit, their limitations are well known.To prove the capabilities of CFD, validation is performed using model scale and full...
In this paper the commercial CFD software package STAR-CCM+ 8.04 was validated against wind tunnel experiments and a qualitative comparison to a non-commercial code was made. NASA’s generic ROBIN helicopter model was adopted for transient simulations to study Rotor-Body interaction (ROBIN). Two different CFD methods have been applied to model the main rotor rotation and the cyclic blade pitching. The first method uses a sliding interface approach where the volume around the entire rotor is modelled in a cylindrical region with a rotating mesh. The cyclic blade pitching has been modelled with...
Computational Fluid Dynamics is about solving difficult engineering problems, using complicated software, enormous computing resources and highly trained engineers. If the problems weren’t difficult, or very important, then it is doubtful that anyone would devote so much effort, time and money at solving them. From the perspective of a modern engineer, it would be easy to assume that this desire to apply simulation technology to complex problems is a recent concern; that only today are we able to contemplate solving tough industrial problems, armed with a complex array of multiphysics...
Having successfully sold coolant- jacket simulation work to Ford in the US, Steve MacDonald began to spread his net wider, and struck up a business relationship with Ford’s European Powertrain Division, based in the UK. One of the engineers at Ford UK was buying some university-type cooperation from this university professor, David Gosman. And of course, it turned out that David Gosman had a CFD code, well a prototype CFD code. Initially when we got into CFD, we were using FLUENT but when we met David, it seemed to me like, well, geez, maybe we ought to cooperate with this guy." David Gosman...
