Jetter Nozzle Of Science From Dublin Institute Of Technology

Flow Patterns Figure 4-2, (DIT Nozzle 2, Shroud 1) and Figure 4-3, (DIT Nozzle 2, Shroud 2) show the shroud for DIT Nozzle 2. To further enhance the regularity of the flow direction a piping system in the top of the part is suggested. This is achieved by increasing the size of the protrusion in the top of the part so that it closes off against the cut-outs in the cap. This protrusion has a number of slots in order to serve as pipes that bring the fluid into the 5mm holes. At the base of the holes, a three dimensional cut-out has been introduced which in conjunction with the core brings the fluid to the exit of the nozzle in an effort to direct the flow in the desired direction. Manufacturing of such a part could be difficult. However if the part is shown to optimise the product then it may be feasible to investigate the design of a similar product which is more convenient to manufacture.
