Towards optimal mixtures of working fluids: Integrated design of processes and mixtures for Organic Rankine Cycles

“…The reduced heat transfer coefficients of mixtures during evaporation and condensation are commonly calculated using a general correlation for pure fluids with a correction factor [92,93]. In this work, a general correlation for flow boiling of pure fluids is used for evaporation, wherein a superposition of forced convection and bulk boiling is assumed [94].…”

Simulation of a rotating drum heat exchanger for latent heat storage using a quasistationary analytical approach and a numerical transient finite difference scheme

“…Therefore, a generalized value of 15 000 W•m -2 •K -1 is used in this study. Details for a detailed investigation of the surface-specific heat transfer coefficient for a boiling HTF can be found in [16]. For the specific properties of water, the data given in [17] are used.…”
