Manufacturing of optimized venturi nozzles based on technical-economic analysis

Abstract

Due to limitations relating to the current manufacturing process of Venturi nozzles, high potentials for increasing the efficiency of the nozzles cannot be used. Initially, CFD-simulations are used to determine the potential for optimization. The simulation also provides details about the requirements in terms of production accuracy and surface roughness of the optimized nozzle. Furthermore, different manufacturing processes, with focus on additive manufacturing, are analyzed with regard to their applicability of manufacturing the nozzles. An economic investigation of the different manufacturing processes is done by using a self-developed calculation tool, which calculates the average production costs per unit and thereby allows a conclusion about the profitability of the different processes.
