The flow nozzle aerator, which is the part of the water tap made up of acryloni-trile butadiene styrene, can be modified entirely with a new design. The curved and cone-shaped slopes are used to improve the smooth flow at uniform velocity. Simultaneously, discharge is optimum by modified interior design. The smooth laminar delivery of water with optimum pressure, the liquid element at the aera-tor end becomes smooth. The assembled nozzle aerator solid model has been generated before experimentation. This can promote through the prediction by the modern tool ANSIFLUENT and CFD for finding the flow behavior and its outlet characters. The solid model can be fabricated to prototype for accurate dimensions by using 3-D printing technology. Comparing fluid motion with the time consumption of filling water has been done over these different kinds of aer-ator and nozzle models, which are fabricated by 3-D printing.
