I could spend my time investigating pretty much all options for the venturi geometry and air gap combinations by simply utilizing the available CAD modelling and parameterization features. Even so I was able to start producing results immediately, literally! It took longer to generate the CAD model than to set up and run the first simulation.

Full 3-D (not even bothering with 2-D or even symmetry), heat conduction in the solids (including the refractory material, insulation layer and steel outer shell) and specifying the flue-gas as a mixture of the various gases. I remember never even bothering with simplifying the model and just going all out from the start. Use CFD for the design and optimization of the venturi geometry, air slip-gap size and pipe diameter to minimize cost and weight. Cooling of the gas was to be established by throttling the gas through a venturi at the end of the stack base and allowing ambient air to be drawn in by the low pressure induced by the venturi. The maximum allowable temperature on the steel pipe was 350☌, therefore the hot gas needed to be cooled sufficiently. The aim was to save on construction costs by using a 9m long steel pipe for the stack instead of building from refractory brick up to the required height. Hot gas coming from a liquor burner at 950☌ must vent through a chimney stack at the required minimum height of 15m. I even recall my supervisor telling me that he would not be able to assist me if I used “EFD” and that he didn’t believe in these “black box” CFD tools…Okay, challenge accepted! Project description We’d be left to our own devices to gain a working knowledge of CFD. Most of us (students) would otherwise have avoided CFD projects like the plague because up to that point, we’d had zero exposure to CFD. It explicitly required the use of CFD for the design and optimization of a flue gas-stack. I was ready and eager to tackle my final year design project, chosen specifically because it was a “CFD topic”. I had just been introduced to Simcenter FLOEFD (back then it was called “EFD”) while doing vacation work at MSC-Africa (the reseller for “EFD”). A bright-eyed and bushy-tailed mechanical engineering student in my final year. In order to demonstrate how Simcenter FLOEFD can be used by designers, allow me to take you on a trip down memory lane… The year is 2007. CFD for design and optimization of a flue-gas stack Simcenter FLOEFD for the Designer Part 4 demonstrates the enhanced turbulence modelling capability of Simcenter FLOEFD (links to the other posts provided at the end of Part 2). Part 3 will look at a real-world example of how the Smart Cells in Simcenter FLOEFD are used. Part 1 introduced some of the main technologies that make the above statement possible. Here we will discuss how these technologies allow designers to use CFD for design and optimization.
