We discuss the theory of cooling electrons in solid-state devices via “evaporative emission.” Our model is based on filtering electron subbands in a quantum-wire device. When incident electrons in a higher-energy subband scatter out of the initial electron distribution, the system equilibrates to a different chemical potential and temperature than those of the incident electron distribution. We...

A theoretical investigation for implementing a scheme of forced evaporative cooling in radio-frequency rf adiabatic potentials is presented. Supposing the atoms to be trapped in a combination of a dc magnetic field and a rf field at frequency 1, the cooling procedure is facilitated using a second rf source at frequency 2. This second rf field produces a controlled coupling between the spin stat...

Gas turbine inlet air-cooling (TIAC) is an established technology for augmenting gas output and efficiency, especially in hot regions. TIAC using evaporative cooling suitable hot, dry regions; however, the limited by ambient wet-bulb temperature. This study investigates two-stage under harsh weather of Riyadh city. The system consists indirect direct stages. In stage, air precooled water cooled...
