Overall Research Project Description Heat is the enemy when operating a fuel tank containing liquid hydrogen. If not properly controlled, a fuel tank can pressurize and even explode due to evaporation (or boiling!). An additional bogeyman is that in microgravity, it can become unpredictable as to where the fuel is in the tank! In order to attempt to combat these problems, one must design a tank with appropriate placement of input nozzles (recooled fuel), liquid acquisition device (remove heated fuel), and baffles. Numerical simulations of the dynamics of the liquid hydrogen take an impractical long time if sub-scale models are not incorporated. This is a multiscale problem in which evaporation occurs on a time scale longer than the scale associated with sloshing dynamics. Because the tank size is on the scale of meters, the Reynolds' number is very large, which in turn influences the representative scales associated with heat convection. In this project, the UROP student will explore possible "fake parameter" solutions so that simulations can be run on a coarse mesh, but still have reasonable agreement with experiments.
Research Tasks literature review (previous models?), data collection (i.e. simulations on coarse grids), data analysis
Skills that research assistant(s) may need: Calculus I recommended
Physics I recommended
computer programming ability recommended
Mentoring Philosophy The ultimate purpose, to me, for the UROP project is to provide a vehicle for the student to continue to gain the knowledge they need in order to better position them for fulfilling their career goals. So, in light of this philosophy, the project itself (hydrogen fuel tanks) can be mutated depending on a given students' goals. Another thing, I collaborate often with other researchers at FSU, other schools, labs, and industry. Always best I think to try and have multiple "mentors" involved because if things work out, that translates to more references ....
