摘要

A crucial requirement of current hood-based calorimetry techniques is the complete encapsulation, collection, and measurement of combustion products. This approach is limited by the need to build supporting infrastructure to facilitate the anticipated fire sizes, such as adequate burn space, a hood structure, and an exhaust system. A proposed approach towards calorimetry is examined in this work, where a sampling plane is established with sampling points placed along the radial direction of the smoke plume. Previous studies were large-scale field trials in outdoor scenarios, with uncertainties contributed by factors such as wind, unknown sampling locations, and limited repeat experiments. This study reduces the uncertainty of this approach by measuring the heat release rate (HRR) of medium-scale kerosene pool fires ( \(D = 0.8{\text{ m}}\) ) floating on calm and wavy water in a controlled laboratory environment with known sampling locations. Results show good agreement with fuel regression analysis and the applicability of the point-based approach in laboratory environments without complete capture of combustion products.
