A Smoke Filling Time Function in Compartment by Dimensional Analysis

Nut NITHIROJPAKDEE

Abstract


A function for illustrating the smoke filling time and related factors in compartment rooms due to various fire movements by dimensional analysis proposed by this study. Dimensional analysis, a numerically expressed physical quantity concept, is applied in developing a function with constants left. Factors effecting smoke filling time are listed for analysis. These factors are height of the compartment room (H), ambient density (), gravity acceleration (g), and ambient temperature (). The factors have been grouped into dimensionless groups. There are 7 Pi groups; these are reduced into the form of a function and can be consolidated in the form of a compact equation through further experiments.
