Turbulent Heat Transfer Enhancement of Microencapsulated Phase Change Material Slurries with Constant Wall Heat Flux

This article presents a novel insight as to the turbulent heat transfer enhancement of microencapsulated phase change material slurries flowing through a circular tube with constant wall heat flux. A turbulent heat transfer model, based on the effective specific heat model, for microencapsulated phase change slurries is presented. Its numerical calculation results agree well with the previously published experimental data. For microencapsulated phase change slurries through a circular tube with constant wall heat flux, the main factors influencing turbulent heat transfer enhancement, Ste, Reb, Mr, ML, and the types of cp curves, are clarified and analyzed in detail.
