Abstract

An artificial dispersion method by spraying water drops has been considered for warm fog without any ice phase process. This method is based on the fallout of tiny fog droplets being collected by the bigger spraying drops. The processes of collection, breakup and sedimentation are considered in the present stochastic model for seeing the spray effect on the stagnant fog. Fog visibility is improved higher than 1000m, meteorological definition of fog, by spraying drops with the economical water supply. It is found all the 240m deep fogs, of which LWC (water liquid content) less than 1g/m³ (55m-300m visibility), will be dispersed within 30 seconds by spraying drops which has 10g/m³ LWC, corresponding to 1.625litre water per square meter.
