Nevertheless, the readily available calculation methods are typically related to homogenous layers, even though hollow or insulated bricks are often used. For this reason, a study of the dynamic thermal performance of insulated concrete blocks is brought forth in the present paper. A finite-volume method is used to solve the two-dimensional equation of conduction heat transfer. An excitation consisting of a triangular temperature-pulse is used to analyse the thermal response of the bricks. The effects of both the type of concrete and the insulating filler are investigated and discussed.7 pagesPDFenUniversity of PretoriaFinite-volume methodConduction heat transferUnsteady heat transfer through wallsThermal response of bricksPresentation
