Gas-transfer at unsheared free-surfaces

WithC. Gualtieri & G. Pulci Doria

Transport processes through the gas-liquid interfaces are of paramount importance in Environmental Fluid Mechanics. In environmental systems gaseous substances may be directly exchanged between air and water in either direction across the air-water interface. Gas fluxes being transferred can be upward to the air or downward to the water depending on the substances involved. Nowadays, despite the significant theoretical, laboratory, field and numerical studies, research efforts have not yet achieved a complete understanding of gas-transfer process.
