Effects of Rectangular Obstacles on the Flow Characteristics of Ultrafine Dry Powder Fire Extinguishing Agent in Confined Spaces

Effects of Rectangular Obstacles on the Flow Characteristics of Ultrafine Dry Powder Fire Extinguishing Agent in Confined Spaces

This study establishes a transient numerical model for the gas–solid two-phase flow of ultrafine dry powder fire extinguishing agents released in the confined space based on the Fluent software platform. The model investigates the spatial flow and diffusion characteristics of ultrafine dry powder un...
