DEVICE FOR ASSISTING IN DETERMINING PLACEMENT OF GAS DETECTION POSITIONS, RECORDING MEDIUM, AND METHOD FOR ASSISTING IN SETTING GAS DETECTION POSITIONS

WIPO Patent Application WO/2012/165158

A1

A computer (100) for assisting in determining the placement of gas detection positions in a detection area receives inputs of information relating to a leakage assumption position that is a position at which gas is assumed to leak in the detection area and information relating to the gas detection positions. The computer (100) then calculates a limit release flow rate that is the flow rate of gas passing through a pipe. The limit release flow rate is a maximum flow rate at which, when the gas leaks in the detection area, the concentration thereof does not reach an allowable concentration outside the detection area. Further, the computer (100) executes a simulation of the gas concentration distribution in the detection area when the gas leaks at the limit release flow rate in the leakage assumption position under each of a plurality of conditions, and calculates and presents, for each of the conditions, the number of positions at which gas with a specific concentration or higher is detected among the gas detection positions, the input of which was received, on the basis of the concentration distribution obtained by the simulation.
