    Abstract

    Experimental and theoretical investigations of mantle tanks for SDHW systems have been carried out. Five differently designed mantle tanks have been tested in a laboratory test facility. A transient three-dimensional CFD-model of one of the tested mantle tanks is made in the CFD-program CFX 4.1. The model is validated against the experimental tests, and good agreement between measured and calculated results is achieved. The results from the CFD-calculations are used to illustrate the thermal behaviour and the fluid dynamics in the mantle and in the hot water tank. With the CFD-calculations, a detailed analysis of the heat transfer from the solar collector fluid to the wall of the hot water tank is performed. The analysis has resulted in a correlation for the heat transfer between the solar collector fluid and the wall of the hot water.
