Heat-Accumulation Stoves: Numerical Simulations of Two Twisted Conduit Configurations
Published in 2013
An important part of the society considers an increased share of renewable energies as an integral part of a strategy towards a sustainable future. As far as heat supply is concerned, this can be achieved using solar thermal collectors, borehole heat exchangers or trough the combustion of biomass. This article shows two applications of two configurations of twisted conduit inside the external coating of the heat accumulation stoves. The hydrodynamic flow is described by the k-є model, the buoyancy is taken into account, the heat transmission is treated into its three components: conductive, convective and radiative. The numerical results are compared with experimental measurements performed in the same configurations.
