Summary on Grant Application Form |
|
Evaporation from the sea surface could be increased if sea water is lifted through the stagnant humid layer at the sea surface using energy from arr offshore, vertical-axis wind-turbines. The water would be sprayed as drops of a diameter such that that substantial evaporation can take place befor residues fall back into the sea. The energy required to lift water in quantities which could make a significant contribution is easily provided direcity by wind. The project will study the possible increase in rainfall and reduction of normal evaporation in drought-stricken countries using available informa the present moisture flux across desert coastlines followed by computer meteorological modelling to predict the effects of an increase of moisture flux its ultimate destination.In parallel with the meteorological work will be the design, construction and testing a series of small spray nozzles with accurate control of drop diameter achieved by notching, piezo pulsation and induced electrical charge intended to establish the essential physics for a full size nozzle.
