The reasoning research on smoke´ spread between ship cabins

The principle of smoke´s spead between ship cabins is founded on the base of the characters of smoke´ spread and cabins´ frame connection, and the direction of smoke movement is analysed. Afterward the cabins´ frame database and PRI of direction are founded, and mathematical model of smoke´ spread between ship cabins is founded with the database. Finally, the simulation software of smoke´ spread is compiled by Visual Basic 6.0. The software can help people judge the direction of smoke, and can provide references to shipman who choose the key nodes which can restrict smoke.
