To meet the requirements of trellis grape crop root irrigation, spraying pesticides on branches and leaves, an integrated sprinkler was designed, which relies flow pressure to change irrigation water spray pesticide working modes. The structural parameters that affect hydraulic performance were selected based principle sprinkler. key for mode included diversion hole inclination angle, refractiv...

In recent decades, electronic devices have tended towards miniaturization, which necessitates the development of new cooling systems. Droplet on a heated wall is effectively used in power with high heat flux densities. The use surfactant leads to an increase diameter wetted spot and rate droplet evaporation. Despite wide interest numerous works this area, there are still unexplored questions re...

to determine the droplet characteristics of agricultural spray nozzles through water sensitive paper (wsp), the non-circular and overlapped spots appearing on the water sensitive paper surfaces are eliminated. in the conventional approach, the procedure is done according to the subjective self determined estimation of the operator. the objective of this study was to develop a practical alternat...
