I need the answer as soon as possible

Note-If not detailed, I will report you. The increasing rates of unplanned fires in both wild and urban settings, especially in the Western portion of the United States, has brought about the need for research concerning the cause of such tragic events. This research project specifically concerns the effects of spot fire ignition on characteristic combustible materials, and modeling them. The grinding or cutting of metal can create metal sparks which can chemically react with the oxygen in the atmosphere. This can cause an increase in their temperature which makes them a potential source for ignition. In the Combustion Fire Processes Laboratory, a computational model has been developed to simulate the reaction process and the distances these sparks travel. This involves solving the equations of motion and the heat and mass transfer to and from the particle. By making models like this, the fire risk posed by metal cutting and other spark producing processes can be better evaluated preventing dangerous and costly fires. What is POVW. Describe the procedure. The ignition of combustible material by hot metal particles is an important pathway by which wildland and urban spot fires are started. Upon impact with combustible material (e.g. vegetation, cellulosic industrial material or polymer foams), these particles can initiate spot fires. In spite of interest in the subject, there is little work published that addresses the ignition capabilities of hot metal particles landing on natural fuels. This work is an experimental study of how the flaming ignition propensity of fuel beds in contact with hot aluminum particles is affected by the characteristics of the fuel bed
