News Fluent Inc., the world leader in computational fluid dynamics (CFD) software, announces the release of FlowLab 1.1 software. FlowLab is a unique piece of educational software that uses the power of flow visualization through CFD to teach basic fluid mechanics principles in the engineering classroom.

The software runs Fluent's general purpose CFD code, FLUENT 6.1, and pre-processor, GAMBIT 2.1, in the background, with a user-friendly, student-specific graphical user interface (GUI) on its front end. Students have been using FlowLab as a complement to traditional lab exercises for two years and this release provides additional features and functionality:

Application Robert Kunz wrote in about his work titled "Modeling of Oxygen Uptake and Particle Deposition in the Human Lung using Homogeneous and Two-Fluid Models".

Researchers at Penn State University Applied Research Laboratory (USA), Center for Medical Diagnostic Systems and Visualization (Germany), and Image Processing Laboratory, Institute of Anatomy and Cell Biology (Germany), are using modern medical imaging technology and three-dimensional, time accurate mul­tiphase CFD to model oxygen uptake and particle deposition in the human respiratory system.

A physically accurate representation of the trachea and most of the convective regime bronchi (up to generation 13) are obtained using high-resolution computed tomography (HRCT) of a rubber cast of an adult human tracheobronchial tree (Fig. 1). A triangulated model of this data is used as a bounding surface for hybrid unstructured meshes generated using the ICEM CFD 4.2 package.

Application: Bringing Simulation Closer to Reality

Application In this story, Dr. David Kinnear describes the challenges which must be overcome when modeling a packed bed chemical reactor.

The [CFD] technique is easy to apply to investigations where there are either no chemical reactions or where the reactions all take place in a gaseous phase. But where solid beds of material catalyse the reactions, the surface chemistry and heat transfer to/from the bed also need to be incorporated.

Initial application of CFD to packed bed reactors has been to just look at a simplified system (for example, just the flow and pressure losses), then infer good or bad performance based on that. Recent developments in CFD software focused on this application are intended to make it much easier to undertake simulations, moving towards direct prediction of performance.
