Hydrodynamics of the Cosmological Quark-Hadron Transition in the Presence of Long-Range Energy and Momentum Transfer

Two previous papers in this series have presented a study of the growth of hadronic bubbles during the cosmological Quark–Hadron transition, treating the material within each phase as a single perfect fluid. Here, we extend the analysis to include the effects of long-range energy and momentum transfer by weakly and electromagnetically interacting particles. After a short review of the formalism adopted, we discuss the numerical strategies used in the computer code which has been constructed in order to solve this system of equations. Results for the growth of single hadronic bubbles are also presented.
