Abstract:
The subject relies on “The National Marine Public Industry Science And Technology Project”. Water jet technology for scallops shelling processing has many advantages: high processing quality; sanitary and safety; material is easy to obtain. Research on the bay scallop in adductor muscle processing was to obtain a new type of scallop in shell adductor muscle processing mode, and water jet on scallop processing was discussed. The nozzle is critical component in shelling equipment, and nozzle parameters would affect the flow velocity distribution. Based on 2-D flow mathematical model, quad-dominated grid was divided. The narrow-angle fan nozzle’s internal flow field was simulated by standard turbulence model. The influence on nozzle velocity distribution such as cone angle, outlet diameter, outlet length were analyzed. After comprehensive analysis, the optimal parameter combination of the nozzle for water jet processing were obtained.
