摘要

The objective of the present work is to study the performance of ejector vapour compression desalination plant with water spray on horizontal tube bundles. The effects of the operating conditions and the ejector geometry on the total distilled collected water are studied. The amount of evaporation rate due the flash evaporation is calculated by applying the mass and energy of the sprayed water governing equations. The evaporation rate of the falling liquid film around the horizontal tube bundles is evaluated by the non-dimensional mass, momentum and energy equations solved numerically using the finite difference method. The results presented the effect of the change in evaporation pressure, inlet liquid temperature, hot surface heat flux and inlet sprayed mass flow rate. Also, the results determine the effect of the ejector geometry, motive steam temperature, evaporator temperature and the compression ratio across the evaporator on the performance of the vapour compression plant.
