Ventilation of mill buildings - new directions.

Natural ventilation of mill buildings is a process which is complicated by several factors such as external wind pressure and local distribution of heat sources. Describes theoretical and small-scale physical modelling techniques for predicting ventilation rates. The theoretical approach using a computer for the numerical aspects allows rapid and reliable assessment of the ventilation rates for very complicated building designs under any appropriate wind conditions. The physical modelling involves small-scale modelling of fluid flow to predict ventilation patterns and the distribution of heat and contaminant sources.
