Investigators at Amirkabir University of Technology Describe Research in Numerical Modeling

  2012 APR 17 - (VerticalNews.com) -- "Thermal energy storage units that utilize latent heat storage materials have received increased attention in the recent years because of their relatively large heat storage capacities and isothermal behavior during charging and discharging. In this study, an analytical approach is presented for the prediction of temperature during the solidification in a two-dimensional rectangular latent heat storage using a phase change material (PCM) with internal plate fins," investigators in Tehran, Iran report.

  "The basic energy equation is formulated accounting for the presence of a heat thermal fluid (HTF) on the walls. A two-dimensional numerical model is developed based on the enthalpy method to predict the distribution temperature of the fin and solid-liquid interface in storage. Results from the analytical solution and numerical model show a good agreement," wrote A.H. Mosaffa and colleagues, Amirkabir University of Technology.

  The researchers concluded: "The developed analytical model estimates satisfactorily the solidification time of PCM in storage, which is useful in the design of PCM-based thermal energy storages and cooling systems."

  Mosaffa and colleagues published their study in International Communications in Heat and Mass Transfer (Approximate analytical model for PCM solidification in a rectangular finned container with convective cooling boundaries. International Communications in Heat and Mass Transfer, 2012;39(2):318-324).
