     nowadays multiple effect desalination plants are used widely in water treatment processes. they utilize thermal vapor compressors instead of mechanical ones. one of the major complexities about thermo-compressors is related to its unstable operational mode. an experimental malfunctioning occurred in a desalination unit established in south pars gas field phases 9&10 with 1718 cubic meter per day capacity. some modifications on the thermo-compressor design were applied and well tested. in the current study a numerical investigation was performed on a malfunctioning thermo-compressor and the source of the problem was observed via a numerical simulation. afterwards, the modifications were conducted on the numerical models and then a perfect analyzed and verified model was selected to manufacture and install. the test results were shown a better performance of thermo-compressor which yields an increase in entrainment ratio and extend the stable region of thermo-compressor working. it is shown that the entrainment ratio is very sensitive to the geometrical parameters of mixing area zone and throat section of thermo-compressor.
