A conventional, axial‐flow, air‐blast orchard sprayer was used to make applications to the outside row of a semi‐dwarf apple block. Fluorescent tracer was applied at the same rate using either disc‐core nozzle sets or air‐induction nozzles fitted with flat‐fan tips. The experiment included measuring the percent area of spray coverage on leaves after three variations in spray application method....

Spraying pesticides using air induction nozzles is a well-known method to reduce drift. These drift-reducing have been tested on many different tree crops (such as apples, citrus, and grapes), but we are still lacking information their utilization hazelnut (Corylus avellana L.) groves, although major nut crop in Italy, recent years its cultivated area has constantly growing. This paper reports ...

We propose a physical model to predict indirect noise generated by the acceleration of compositional inhomogeneities in nozzles with viscous dissipation (non-isentropic nozzles). First, we derive quasi-one-dimensional equations from conservation laws multicomponent flows. Second, validate proposed experimental data available literature for binary mixtures four gases. Third, calculate nozzle tra...
