  THERMAL RADIATION IN A COMPARTMENT FIRE


    An IMMERSOL application is presented aimed at the demonstration
    of the method for the simulation of fire in a 3D enclosure when
    the convection, chemical reactions, thermal radiation and
    conjugate heat transfer in the internal structures have to be
    considered simultaneously.

    The demonstration case considered consists of rectangular room
    with an internal wall of finite thickness and door opening at
    the front end of the room. The dimensions of the room are those
    of the Test Compartement used by Swedish National Testing
    Institute for calibration experiments.

    It is supposed that a fuel (methane) leaks from the
    communication system and enters the room vertically upwards
    through an aperture located at the floor in the bottom of the
    rear wall. In the vicinity of fuel leak, there is a vent
    supplying the air for heating and ventilation purposes.

    The fuel is ignited on entry and steady combustion is in
    progress producing the high temperarture combustion products.
    Their movement is greatly influenced by buoyancy with the
    salient features as follows:
  
  The task is to calculate the temperatures of the internal wall
  structure and combustion gases along with all related field
  distributions.
