    Performance Assessment of a Liquid-Phase-Separation Refrigeration Cycle 

    Darwish, Naif A.; Gadalla, Mohamed (Wiley, 2012-10)
    Absorption refrigeration cycles are alternatives to conventional vapor-compression cycles in which the energy required for refrigeration is provided by heat instead of mechanical work. In this paper, a novel refrigeration ...

    Economics of hydrogen production and liquefaction by geothermal energy 

    Yilmaz, Ceyhun; Kanoglu, Mehmet; Bolatturk, Ali; Gadalla, Mohamed (2012-01)
    Seven models are considered for the production and liquefaction of hydrogen by geothermal energy. In these models, we use electrolysis and high-temperature steam electrolysis processes for hydrogen production, a binary ...
