Spectral radiative properties prediction model and parameter identification for open cell foam insulation.

Author(s) : DOERMANN D., RAYNAUD M., SACADURA J. F.

Summary

In the paper a special emphasis is given to input data determination. Particle dimensions and porosity can be obtained from microscope analysis. But solid hemispherical spectral reflectivity is very difficult to obtain directly. It is determined by an identification method applied to bidirectional spectral transmittance data obtained from an experimental device. Results obtained from this approach are consistent. A good agreement is observed between experimental results of transmittance and reflectance and theoretical data.
