🟠 Convection Currents in a Lava Lamp - 2D Cross-Section, Stokes Rise and Thermal Cycle

2D companion of the lava lamp convection sim: blob buoyancy from the wax/oil thermal-expansion difference, Stokes terminal speed, lumped heat exchange with a stratified fluid, collisions and a Reynolds number, with two numerical checks.
