In the first attempt at finding a solution to this model, the wrong kinematic viscosity was used. This permitted a solution to be found, but it was worthless. Once the correct kinematic viscosity for air was given, the steady state model would just diverge. The reason appears to be the simple fact that the model…

It’s a very idealised version of a clamp, but it feels pretty OK. The clamp is 8m wide, 2.4m high, and the cross section is 3m broad. The ventilation pipe is 20cm in diameter, and 5.5m long, from x = 0. There are 12 holes in the pipe, each 6cm in diameter and centered at…

To verify my CFD model of a sugar beet clamp, measurements of air speed inside of the clamp are desired. It’s something that I have not been able to do with a simple, post-clamp-construction method. In 2021, it is time to test a more embedded, set-up-at-harvest method. To this end, I’ve turned to do-it-yourself electronics.…

As part of the CFD course I’ve just been through, we had a group assignment. My team was kind enough to adopt the beet ventilation system we at NBR are developming to be the focus of our work. Here is the report (it’s pretty technical and unfortunately not highly conclusive): I hope we’ll get to…

Drying out sugar beets isn’t usually a practice undertaken in their production – at least, not intentionally – and we’re not looking to change this – intentionally. The topic has come up after it became clear in one of my other projects that ventilation isn’t just good for cooling beets, it has the ability to…

If there is one thing that I hope to know more about than anyone else in the world at the end of my PhD, it is how air moves through sugar beet clamps, and how this air movement impacts the quality of the beets over time. To this end, one of the major research trials…
