VenturiNozzleAnalyzer: Decision-Support Software for Engineered Air-Nozzle Retrofits in Compressed-Air Systems

The software generalizes an Industrial Assessment Center (IAC) recommendation into a reusable tool.</p><p dir="ltr">It includes:</p><ul><li>a choked-orifice flow model with subsonic-flow correction,</li><li>adiabatic compression work evaluated with absolute pressures,</li><li>energy and demand tariffs, implementation cost, and simple-payback analysis.</li></ul><p dir="ltr">The proposed nozzle can be represented either as a reduced orifice or by its catalog air consumption, with optional pressure regulation.

Built-in consistency checks flag simultaneous air demand exceeding compressor capacity, power reductions above 50% of compressor input, subsonic flow, and the OSHA 30 psi dead-end pressure limit. The application supports US customary and SI units, USD/EUR/TL currencies, a built-in IAC case study, an input guide, four engineering plots, and export to XLSX, TXT, and PNG. This Figshare item contains the standalone Windows executable (.exe), the C# (.NET 8) source code, and the case-study input and output data.</p>
