Okoosi, (2019): Some New Results on a Free Boundary Value Problem Related to Auto Ignition of Combustible Fluid in Insulation Materials, proceeding of the 6th Annual International Conference on Mathematical Analysis and Optimization: Theory and Application (ICAPTA 2019): 95 – 105http://repository.futminna.edu.ng:4000/handle/123456789/2038Auto ignition of combustible fluids in insulation materials is one of the major problems facing the processing industries and many developing nations because it leads to serious environmental problem. This paper presents an analytical solutions to a free boundary value problem related to auto ignition of combustible fluids in insulation materials. The aim is to ascertain whether such a system is safe or if it will undergo ignition for a particular set of conditions. The conditions for this existence of unique solution of the model is established by actual solution method. The properties of solutions is examined. The analytical solution is obtained via polynomial approximation method, which show the influence of the parameters such as the Lewis numbers and Nusselt number are presented graphically and discussed.enAuto ignitioncombustible fluidsfree boundary value problempolynomial approximation methodArticle
