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.
