Happy Winter Solstice 2018!
Today’s post is something a little light hearted as it’s the shortest day of the year in the southern hemisphere. I was (re)watching the Hitch Hikers Guide to the Galaxy movie last night and was inspired by the scene above Magrathea where a pair of nuclear missiles are turned into a bowl of petunias and a sperm whale (Physeter macrocephalus), respectively. If you’re not familiar with this here is an extract from the movie:
Or better yet, buy all the books and then read them.
For this work I’ve made some assumptions and the whale is travelling head first rather than belly first as in the move. The grid is pretty rough and was generated using the CFD-VisCART adaptive cartesian mesher – you can see the refinement boundaries. I used CFD-FASTRAN as the density based solver for the supersonic flows.
