Jacob Bear Short Course – Day 4

without comments

The course is over. Instead of blogging immediately about day 4, I spent the evening in Torino and hung out with some people from the course. At this point I have to point out how nice the city of Torino is, how nice and willing to help the people are. In the town, during the days of my visit, I was asked at least three independent times, if I needed help! On the final evening, we sat down on a bench on one of the plazas, and an elderly man started to talk to us in Italian, slowly and very well understandably. He ended up walking with us through the old city four over an hour and pointed out places of interest. It was just wonderful!

On the last day we covered heat transport and transport with fluids of variable density, especially sea water intrusion. From a historical point of view it’s interesting that because of sea water intrusion, density dependent models were the first “contamination” models to be developed. That is before dispersion was developed, and hence sea water intrusion was treated with sharp interfaces. We learned about the “Hele Shaw Model“, which Jacob Bear has used to model sea water intrusion before the use of computers was feasible. Bear developed during his M.Sc. thesis a horizontal Hele Shaw model. His first bookhas a full section on constructing Hele Shaw models. The idea seems from a former time, but such a model could have its uses for education!

In the afternoon, Dr. Rajandrea Sethi gave a presentation on how his group models colloid- and nano-particle transport under saturated conditions.

These were just amazing four days in Torino. It was such an interesting approach – to hear essentially a short but complete version of porous media theory in four days. Jacob Bear as teacher for this short course was amazing. Every word he uses has a meaning, everything he says builds up consecutively, and he stresses the important points. I will have many ideas to write about in the next little while for sure! 🙂
