  • Study of a constrained-film bubble absorber under cycle operating conditions

    Creator:
    Cardenas, Ruander
    Abstract:
    An experimental and numerical study of absorption of ammonia vapor bubbles into a constrained thin film of ammonia-water solution is presented in the context of a potential reduction in size of a heat-actuated heat pump component. A large-aspect-ratio channel with a depth of 600 µm restricts the thickness of the...

  • Submerged jet impingement boiling thermal management

    Creator:
    Cardenas, Ruander
    Abstract:
    Technologies such as avionics and power electronics are driving the demand for thermal management schemes towards high heat fluxes and low surface temperatures. Typically, these applications require the dissipation of heat fluxes in the rage of 100-1000 W/cm² while maintaining surface temperatures lower than about 85 °C. Phase-change heat transfer...
