Experimental and Numerical Investigation on Ignition and Horizontal Flame Spread for Recycled Plastic Pellets

Fire and Materials, EarlyView.
ABSTRACT Fires in recycling facilities are known for producing noxious fumes, having high heat release rates (HRRs), being difficult to extinguish and causing significant devastation to business operations. This research aims to provide experimental data and numerical models from which performance‐based designs can be developed for recycling facilities.
