numerical study of water production from compressible moist-air flow

In this research a numerical study of water production from compressible moist-air flow by condensing of the vapor component of the atmospheric air through a converging-diverging nozzle is performed. the atmospheric air can be sucked by a vacuum compressor. the geographical conditions represent a hot and humid region, for example bandar abbas, iran, with coordinates, 270 11’ n and 560 16’ e and summer climate conditions of about 40℃and relative humidity above 80%. parametric studies are performed for the atmospheric-air temperature between, 40℃ to 50℃, and relative humidity between49.6% to 100.%. for these ranges of operating conditions and a nozzle with the area ratio of 1.17, the liquid mass flow rates falls in the range 0.272 to 0.376 kg/s. the results show that, the energy consumed by the compressor for production 1 kg of water will be 1.279 kwh. the price of 1 kwh is 372 rials, therefore the price for the production of 1 kg liquid water will be 475.8 rials, therefore, the scheme is economically suitable.
