Effects of Gravity-Driven Convection on Microstructural Development during Directional Solidification of Particle Suspensions

Description:

Directional freeze-casting is a porous materials fabrication technique that is used to create materials with complex, three-dimensional pore structures. Particle suspensions are solidified under a thermal gradient, promoting anisotropic growth of dendrites and incorporation of particles within interdendritic space. A fully-solidified directional freeze-cast structure is composed of dendrites that are...

Topics on Planet-Disk Interaction and Solar Convection

Description:

In this thesis I focus on two topics: planet-disk interaction and solar convection. These two seemingly separate topics are connected via a similar separation of timescales. Planets excite spiral waves in their disks on fast timescales compared to the time for the disk to viscously adjust to the angular momentum...
