This presentation was held at the 2020 NAFEMS UK Conference "Inspiring Innovation through Engineering Simulation". The conference covered topics ranging from traditional FEA and CFD, to new and emerging areas including artificial intelligence, machine learning and EDA.

Resource Abstract

The efficiency and functionality of contemporary tile stoves are numerically evaluated using a commercial finite volume flow solver including heat conduction in solids and compared to experimental results. Careful selection of material and numerical parameters has been necessary to simulate the complete heating cycle over several hours, which so characteristic for this type of stove. The impact of the stoves heating cycle on the room temperature is investigated in a real scenario, where the stove is positioned in a generic house or flat as an unsteady boundary condition based on detailed preceding simulations of the stove itself. Comfort parameters are evaluated at different locations in the vicinity of the stove.

Tile stoves have been used for centuries for heating of homes and houses. Typical for this type of stove is, apart from its construction, its particular usage due to its capabilities to store heat over a long time. The stove is mainly built from chamotte, a material with a high heat capacity but rather low heat conduction. Together with its peculiar interior construction, this type of stove is only initially heated up by burning fire wood and then emits heat for several hours. In the course of strengthening the usage of renewable energies, these stoves have regained popularity as well as due to their unchallenged look and feel.
