Behavior of thermal insulation materials under fire conditions with reference to their position within building envelopes
Abstract
The aim of the present thesis was the determination of the behavior of thermal insulation materials in fire, in reference with their type, position and width on the behavior of a typical Greek apartment’s fire enclosure. The research was performed by the method of comparative parametric analysis of the basic design variables of the building envelope. For the research an advanced computational fluid dynamics model was incorporated, using specialized fire simulation software. The thermophysical properties of all building materials used in fire simulations were considered as functions of temperature, while all the relevant thermochemical processes were simulated. The data of the relevant material properties of the most commonly used building materials used in Greece were collected through an extensive literature review. In addition, a one dimension heat transfer model is proposed for the perforated brickwork, capable of accurately predicting the evolution of surface temperature on the une ...
