Beamed ceilings and smoke flow explained through real‑world tests
This report compares a field model of smoke movement with laboratory experiments that use beams to shape the flow. It examines how temperature rises and drops travel through channels formed between beams, and how well the numerical predictions match measurements.
The study focuses on two experiments with different beam depths and spacings. It describes grid setups near the floor and ceiling, the interpolation of instrument data, and how the model captures the main features of the plume and channeling. The author shows that the field model can predict the time history of temperature rise and the drop off across adjacent channels, with some locations near the fire presenting greater measurement sensitivity.
- How beams channel smoke and create distinct temperature patterns
- How grid resolution and interpolation affect accuracy near the fire
- How changing beam depth and spacing changes results between experiments
- How numerical and experimental data compare across multiple sensor locations
Ideal for readers of fire dynamics, ventilation modeling, and engineering simulations who want a practical look at validating field models against experiments.
