In this project, the fluid flow behavior in the Dry Gas Seal was numerically simulated and analyzed using ANSYS Fluent software to evaluate the hydrodynamic performance of the seal grooves under different operating conditions. The process included creating the geometry, generating a high-quality mesh, defining boundary conditions, and solving flow equations to investigate the pressure distribution, velocity, flow pattern, and gas layer capacity between the sealing surfaces. The analysis results showed the role of groove geometry and operating parameters in creating gas film stability, reducing leakage, preventing surface contact, and increasing seal life. This simulation was used as an effective tool to optimize the design of the Dry Gas Seal and increase the reliability of rotating equipment in the oil, gas, and petrochemical industries.
