The characteristics of fluid flow inside a test setup for mechanical seals were determined using Laser Doppler Velocimetry (LDV) testing, as well as Particle Image Velocimetery (PIV) testing. LDV was used to determine azimuthal components of flow, and PIV testing will be used for the axial and component.. These tests were conducted at 1000 and 1800 rpm. The LDV data obtained for the azimuthal component gave a velocity and turbulence profile that agreed at both the 1000 and 1800 speeds. The PIV data obtained was accurately taken in the rotor region, but problems occurred in the rotor/stator gap region. In addition to this, a test design was laid out to determine the heat transfer coefficients along the seal at various rpm. From this testing, thermal stresses in the seal can be studied.
