A numerical analysis on a solar chimney with an integrated latent heat thermal energy storage

Summary

Transient two-dimensional CFD simulation, using a k-ε turbulence model in Ansys Fluent, of a south-facade building solar chimney whose absorbing wall carries a layer of phase change material. The converging channel, 4 m tall with a slightly tilted glazing, is analysed through wall temperatures and air velocity and temperature fields to guide design of the storage-integrated system.
