The regional pollutant budget of the atmospheric boundary layer: Concept, interpretations and observational results

Regional budgets of pollutants in the atmospheric boundary layer (ABL) provide valuable information on transport and chemical processes, especially over complex terrain where local assessments are not representative.Horizontal transport, vertical transport (advective and non-advective), deposition, emissions and chemical production/destruction cons

Injection Of air control of propeller performance

With the rise of bubble lubrication technology in transport ships, the interaction between propellers and bubble flow has become increasingly important.On the basis of solving the Reynolds averaged equation and the volume fraction equation, a numerical model of the propeller in a water air mixed fluid was established using the sliding mesh techniqu
