Abstract

The bachelor’s thesis is focused on the comprehensive optimization of the internal geometry of a fire sport nozzle using numerical simulations in the Simcenter 3D environment. The aim of the thesis is to design a configuration of the internal flow channel and flow- straightening elements that ensures the minimization of energy losses and an increase in the stability of the outgoing water jet. The optimization process is divided into two main phases. The first part deals with the CFD analysis of 46 geometric variants, in which the influence of the internal geometry on the flow characteristics is evaluated using multicriteria assessment. The second phase of the thesis integrates structural analysis using the finite element method, which is used to optimize the nozzle wall thickness with respect to strength requirements and the resulting structural weight.
