Description
The hydrodynamics of expanding bubbles plays an important role in the study of gravitational wave emission from first-order phase transitions. It determines the possible expansion types and provides an estimate of the energy available for gravitational wave emission. By interpolating between electroweak- and QCD-like transitions, I will investigate the hydrodynamics of expanding bubbles in transitions with non-conformal thermodynamics. In doing so, I will uncover a new set of obstructions to bubble expansion and a new class of bubble solutions, both of which are absent in electroweak-like transitions, and I will discuss their impact on the space of solutions and the kinetic energy fraction.
