    Geometrical modification and finite element analysis of a sprinkler
    Boniface, Rowland Pamphil; Bodzás, Sándor; DE--Műszaki Kar
    In fluid flowing systems the machines involved can be grouped as either turbo machines or positive-displacement machines. A machine will be grouped as a turbo machine (centrifugal machine) if it adds or extracts energy from a fluid usually using a rotating component. If the fluid energy utilization is by extraction of the energy from the fluid then the machine is called a power machine. If the fluid energy utilization is by addition of energy to the fluid then the machine is called a work machine. All centrifugal machines have one or more rotating parts called rotors. [1] A sprinkler is an example of many turbo machines used. A water sprinkler or just sprinkler is a device used for irrigation purposes in gardens, farm etc. Water at pressurized form is supplied to the sprinkler at the inlet port and the sprinkler ejects the water into the air where it then falls down in form of water droplets. The aim of this study is to first perform a geometric modelling of the sprinkler using CAD software, then perform a flow analysis using Ansys software to study how total pressure, static pressure and water velocity can change and vary when the sprinkler model is modified. With the results we can learn how flow properties can change under certain modification in the flow paths. Figure 1 below shows a water sprinkler designed by CAD Software (SolidWorks 2022).
