  1. 1. Fundamental design approaches for improvement of the fire safety in car parks Research activities planned by the Industrial Safety research group of K.U.Leuven Dr. Filip Van den Schoor Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
  2. 2. Overview Industrial Safety research group Objectives Planned research activities Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
  3. 3. Industrial Safety research group Past and current main research activities: • Flammability limits • Auto-ignition limits • Consequence modelling Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
  4. 4. Industrial Safety research group Laboratory for Industrial Safety (LIV) Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
  5. 5. Industrial Safety research group Spin-offs that originated from the Industrial Safety research group: • Adinex: expert advice on explosion safety (prevention, protection and mitigation, incident analysis,...) • Protec Engineering (now part of M-tech): safety reports (risk analysis, consequence modelling) Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
  6. 6. Industrial Safety research group Mechanical Engineering Department Division of Applied Mechanics and Energy Conversion Applied Combustion Energy & Environment Engine Technology Industrial Safety Thermal and Fluids Engineering Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
  7. 7. Industrial Safety research group Relevant research activities by other research groups: • Turbulence modelling • Combustion modelling • Particle image velocimetry Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
  8. 8. Objectives The study focuses on the following aspects in car parks: • smoke control in case of fire; • explosion risk; • structural aspects (structural integrity and reliability assessment). Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
  9. 9. Objectives With respect to the explosion risk, the objectives are: • to carry out an approximate quantitative risk analysis (QRA) of the explosion risk in closed and semi-closed car parks due to the presence of vehicles fuelled with LPG and hydrogen; • to gather experimental and simulation data for the derivation of simplified calculation methods for the design of gas detection and ventilation systems, for closed and semi- closed car parks. Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
  10. 10. Planned research activities Gas dispersion experiments and modelling (WP 3) Hot surface ignition experiments (WP 3) Quantification of explosion effects (WP 3) Reliable design calculation methods (WP 5) Quantitative risk analysis (WP 7) Dissemination (WP 8) Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
  11. 11. Planned research activities Gas dispersion experiments and modelling: full-scale CFD simulations reduced-scale full-scale wind tunnel field experiments experiments reduced-scale CFD simulations Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
  12. 12. Planned research activities Hot surface ignition experiments: objective: to experimentally study the ignition of stagnant and flowing flammable mixtures by hot surfaces in order to determine the probability that an accidental fuel release will lead to a vapour cloud explosion possible “hot spots”: engines, exhausts, brakes,... Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
  13. 13. Planned research activities Quantification of explosion effects: explosion scenarios: • rupture of a fuel tank filled with a liquefied fuel BLEVE (boiling liquid expanding vapour explosion) • delayed ignition of a leak of a fuel tank VCE (vapour cloud explosion) explosion effects: blast pressure, thermal radiation and fragments based upon exisiting analytical calculation methods Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven

  15. 15. Planned research activities Reliable design calculation methods: ventilation system: smoke control and flammable gas dispersion gas detection system: e.g. spacing of gas detectors guidelines for explosion risk reduction Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
  16. 16. Planned research activities Quantitative risk analysis: defining potential accident scenarios (fire, BLEVE,...) estimating consequences estimating probabilities estimating and evaluating risk identifying risk reduction measures Laboratorium Industriële Veiligheid Departement Werktuigkunde, K.U.Leuven
