    Abstract

    Characteristics of vertical mantle heat exchanger tanks for SDHW systems have been investigated experimentally and theoretically using particle image velocimetry (PIV) and CFD modelling. A glass model of a mantle heat exchanger tank was constructed so that the flow distribution in the mantle could be studied using the PIV test facility. Two transient three-dimensional CFD-models of the glass model mantle tank were developed using the CFD-programmes CFX and FLUENT.The experimental results illustrate that the mantle flow structure in the mantle is complicated and the distribution of flow in the mantle is buoyancy dominated. The numerically predicted flow distribution was found to be in good agreement with the experimental results. The numerical results were also found to be independent of the grid system used to model the convection processes on either side of the mantle heat transfer wall.
