    Role of heat transfer in bubble dynamics neglecting phase change. A numerical study 
    Fostiropoulos, Stavros Rafail; Malgarinos, Ilias; Strotos, George; Nikolopoulos, Nikolaos; Kakaras, Emmanouil; Koukouvinis, Phoevos; Gavaises, Manolis (Editorial Universitat Politècnica de València, 2017-07-28)
    [EN] Bubble dynamics is generally described by the well-known Rayleigh-Plesset (R-P) equation in which the bubble pressure (or equivalently the bubble density) is predefined by assuming a polytropic gas equation of state ...

    Supercritical and transcritical real-fluid mixing using the PC-SAFT EOS 
    Rodriguez, Carlos; Vidal, Alvaro; Koukouvinis, Phoevos; Gavaises, Manolis (Editorial Universitat Politècnica de València, 2017-07-28)
    [EN] A numerical framework has been developed to simulate the mixing of supercritical and transcritical fluids using an equation of state based on statistical associating fluid theory. In a Diesel engine the liquid fuel ...
