  1. 1. Flight Dynamics Software Industrialisation for Inclined Orbits

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Pierrick Houede; [2023]
    Keywords : flight; dynamics; software; FDS; geostationary; orbit; station; keeping; uncontrolled; inclination.;

    Abstract : The geostationary orbit has many applications for Earth observation and telecommunications. Like all satellites, spacecraft in this type of orbit are affected by perturbations. These perturbations can modify the satellites trajectories and, without control, deviate them from their target position. READ MORE

  3. 2. Exploring the Feasibility of Using Fire Dynamics Simulator to Improve the Calculation of the Wildfire Available Safe Egress Time

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Alfred El Haddad; [2023]
    Keywords : Wildfire; Trigger buffer; WUI; WASET; FDS; QGIS; Level set; WUI evacuation.; Technology and Engineering;

    Abstract : Wildland-Urban Interface (WUI) fires pose a significant threat to public safety and property in areas where urban development encroaches upon natural landscapes. This thesis aims to investigate the effect of smoke from a WUI fire on the tenability conditions of a small village and to establish a worst-case-scenario trigger boundary around it as an improved basis for the WUI available safe egress time (WASET).

  4. 3. EVALUATION OF MULTI-ZONE MODELLING FOR FIRE RISK ASSESSMENT IN TUNNELS

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Annachiara Nardone; [2023]
    Keywords : tunnels; tunnel fires; multi-zone modelling; Technology and Engineering;

    Abstract : Abstract Tunnels are one of the most complex and delicate elements of the road system. Assessing fire behaviour and fire severity remains the biggest source of uncertainty in risk assessment and is an essential step in the tunnel design process. READ MORE

  5. 4. A Comparative Study of Fires in Corners and Along Walls

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Josef Utterfors; Adam Tegenfeldt; [2022]
    Keywords : Fire; wall; corner; hot gas layer; flame height; plume temperature; Technology and Engineering;

    Abstract : The topic of fires in corners and along walls has been studied previously, however, two different studies conducted in 1987 and 2018 respectively, produced conflicting results regarding plume temperature for fires along walls, as well as hot gas layer temperature for both fires in corners and along walls. This thesis seeks to add data and clarification about fires in corners and along walls. READ MORE

  6. 5. The Heat reducing Effects of Reflective Clothing in Firefighting : A study on the efficiency of reflective textiles in personal protective equipment

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Albin Henning; [2022]
    Keywords : Firefighter; Reflective textiles; Radiant heat; Protective equipment;

    Abstract : Modern firefighter protective equipment is excellent at protecting firefighters from surrounding heat, but how effective is at deflecting incoming radiant heat, and would the use of more reflective textiles, be able to further increase the equipment’s protective properties? This study aims to understand the different properties that reflective materials, compared to standard firefighter outer layers, have against radiative heat flux. The textiles of firefighter turnout gear and the reflective textiles used in the smelting industry have been examined when exposed to varying levels of radiant heat in a cone calorimeter. READ MORE
