A017 Smoke spread in shafts

Smoke spreading in vertical shafts in buildings with scale modelling technique

Brief:

Smoke movement pattern in a lift shaft was studied with a scale model. Three cases were considered with the fire at the bottom of the lift shaft; in a compartment next to the lower part of the lift shaft; and in a compartment next to the upper part of the lift shaft. Empirical correlations on the smoke travelling time were derived from the results reported in this study.

This is part of the MPhil project work of P.M. Tang (MPhil).
