Effect of Convection on Latent Heat Storage in a Tube and Shell Exchanger

Abstract

The Lattice Boltzmann Method is a very strong numerical modeling method that has proved its effectiveness in many areas of study, especially in the field of fluid flow and thermo-hydrodynamic problems. In this paper, we present a new numerical study involving a tube and shell heat exchanger to evaluate the heat storage phenomena, and especially the effect of convection on storage enhancement. A case study and numerical results are provided using.an axisymmetric Lattice Boltzmann model. The results obtained show that convection accelerates latent heat storage.
