Abstract: The present study aims to understand the leakage flow rate parameter of labyrinth seals with respect to the different profiles and validation of leakage flow rate through experimental setup known as seal test rig for labyrinth seals. The different labyrinth seal profiles are designed using CATIA software and CFD analysis is performed to study the mass flow rate at inlet and outlet of the labyrinth seal, results in terms of pressure, velocity distribution profiles, pressure, velocity contours, turbulence dissipation rate, turbulence kinetic energy, velocity field are tabulated, studied to understand the mass flow rate through a labyrinth seal and study aims to conduct static analysis, modal analysis using ANSYS software & CFD analysis using COMSOL Multiphysics software. The results and observations are tabulated and compared to analyze the leakage flow rate of labyrinth seal for different configurations and design changes.
