Magnetic influence on water evaporation rate: an empirical triadic model

Over the past decades researchers have described what happens to the water when a polarizing external field is applied to it and changes the bonding forces existing in it. Water evaporation, an essential process in nature, has been targeted in a great number of studies. In this paper, static magnetic fields ranging from 30-to-200 mT were applied to circulating purified water to study their effect on how the evaporation rate changed under different ambient conditions. A statistical approach was employed to verify the significance of the magnetically induced effect. Our results showed that by applying a static magnetic field to the water, the evaporation rate increased at lower temperatures, yielding an evaporation increase for magnetized water of up to at 6 °C. We found too that the circulation of the water did not contribute significantly to the evaporation rate. We used an empirical triadic model to correlate the applied magnetic field with the ambient parameters of temperature and humidity. ; This work was supported in part by the Ministerio de Ciencia, Innovación y Universidades (ID: PGC2018-096994-B-C22), the Ministerio de Economía y Competitividad -Infraestructura FEDER- (ID: EQC2018-004395-P), and by Funding for open access charge: Universidad de Huelva/ CBUA. ; Ciencias Agroforestales ; Ingeniería Eléctrica y Térmica, de Diseño y Proyectos
