Design and Fabrication of Spiral Water Nozzle Jet

Abstract

Spiral water nozzle jet is one of a new study for enhancement of capability of wide range usage namely fire fighting, cleaning apparatus and fire suppression system or where is needed. This paper assesses the influence of parameters on long nozzle, spiral criteria, the characteristic of flow and selection of material. Since the limitation of making spiral in small hole which crucial in water jet, the study on design of cutting tools is included. Experiments were conducted in varying water pressure, nozzle and spiral length, nozzle and spiral angle, depth and number of spiral and pattern of spray water. The effects of these parameters on spray pattern have been studied based on the experimental results. In order to correctly select the process parameters, an empirical model of Aluminum Alloy 1060 for the prediction of result such as velocity and spray pattern was developed using regression analysis beside of simulation analysis. This developed model has been verified with the experimental results that reveal a high applicability of the model within the experimental range used.
