<P>PROBLEM TO BE SOLVED: To solve the problems that simulation by a computer has become a useful means in safety evaluation of a building to occurrence of fire and a poisonous substance and examination of an operation method of safety equipment, however, in a large building in recent years, a wide space in the complicated shape is mixed besides a rectangle sitting-room with the simple shape, evaluation of density distribution is not easy when smoke, the poisonous substance, and heat by the fire occur, namely, a calculation amount becomes huge in the conventional three-dimensional fluid analysis technology, and on the contrary, the complicated shape cannot be coped with practical macro model fluid analysis technology. <P>SOLUTION: Calculation is efficiently performed by adapting three-dimensional analysis technology to a part required to be simulated in details and adapting the macro model fluid analysis technology to a part for which detailed simulation is unnecessary in consideration of the shape of the building. By an analysis model of a disaster prevention facility in occurrence of the fire and the poisonous substance, its effect is reflected on simulation, and in addition to the case of taking/not taking a measure, an effect like timing of the measure is quantitatively examined. <P>COPYRIGHT: (C)2009,JPO&INPIT |
