  2. 1. Fire Dynamics in Multi-Room Compartment Fires

    Author : Nils Johansson; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fire safety engineering; fire dynamics; multi-room compartment; numerical experiment; small-scale experiment; hot-gas-layer temperature; hot-gas-layer interface height; reproducibility;

    Abstract : Fire dynamics in multi-room compartments are explored in this thesis and new methods to study conditions in rooms adjacent to the room of fire origin are presented. Simple and transparent engineering methods can create good possibilities for understanding different complex phenomena present in fire science. READ MORE

  4. 2. Numerical experiments - a research method in fire science

    Author : Nils Johansson; Avdelningen för Brandteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; experimental uncertainty; accuracy; fire dynamics; compartment fires; models; experiments; Numerical experiments;

    Abstract : Fires are complex and it is hard to derive relationships from theory in fire science. Full-scale and small-scale experiments have been used with great success in order to increase the understanding of fire chemistry and fire dynamics. But, there are shortcomings and difficulties with conducting these traditional fire experiments. READ MORE

  5. 3. On the Lifecycle Management of Standards

    Author : Nils Johansson; Innovation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EDI; SASIG; ODETTE; Standard; ENGDAT; OFTP; PDQ; PDM; eXchange and Management of Technical Data; LMS;

    Abstract : Standards are used everywhere in the modern world and are a fundamental part of a functioning society. But the creation and maintenance of international standards is not an easy task. In addition to the technical prerequisites that must exist to create a standard, there are also political, economic and cultural aspects that must be considered. READ MORE
