3D printing and CAE analysis of spraying nozzles for different orifice sizes

The solid model of the nozzles was created, and the prototype was produced with the help of a 3D Stratasys printer. Afterwards, an analysis of three flat fan nozzles (N1, N2, and N3) with different orifice sizes (1.050 mm, 1.150 mm, and 1.340 mm) using Computer-Aided Engineering (CAE) techniques. The purpose of the analysis is to evaluate the structural and computational fluid dynamics aspects of these nozzles. In the analysis, the nozzles were subjected to external forces 1N, 2N 3N and total deformation (mm), equivalent elastic strain, equivalent stress (MPa) parameters were evaluated theoretical calculations are done and CFD simulations are also done on the nozzles surface using ANSYS Workbench software version 2021 R1 and computational fluid analysis of nozzle. The objective of conducting this analysis is to identify potential points of failure and evaluate the structural performance of the nozzle under the given external forces. By understanding the behavior of the nozzle under these conditions, design improvements can be made to minimize the risk of failure during its operational use. The validation of these formulae is carried out using the Computational Fluid Dynamics (CFD) software ANSYS Fluent.
