   Sammanfattning : Evaluation of fire fighting spray nozzles when cooling hot smoke gases in a compartment fire. Computer simulations have been made concerning the fire scenario and time to reach fire control when water is applied. Total amounts of water are also calculated. Suggestions and conclusions drawn from the results are shown in the report. LÄS MER
