The swollen polymer technique
Abstract
The swollen polymer technique for measuring heat transfer in gas turbine steady state facilities is described. It is a combination of the swollen polymer approach to mass transfer and laser holographic interferometry. The former is used in place of the sublimating naphthalene surface and the latter replaces the associated mechanical profilometric measurements with optical measurements. Application to the measurement of adiabatic wall effectiveness on film cooled surfaces is outlined.
