Differential Equation Solution of Heat Transfer of Polyethylene Terephthalate Fiber and Composite Concrete as a Thermal Neutron Shielder

Heat behavior especially flowing and distribution of heat in materials are very important for considering the selection of materials to be suitable for various activities, being able to predict or explain thermal behavior can be considered very useful in engineering field. This research focused on finding general mathematical models to explain or predict heat flow phenomena in fiber reinforced concretes. The study found that heat dissipation in fiber and concrete materials can be explained by nonhomogeneous partial differential equation by setting simple appropriate initial conditions for analysis the models.
