Concept explainers

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Can someone please help me with creating an excel spreadsheet to calculate heat transfer phenomenon from a cylindrical fuel rod to the coolant? The excel sheet needs to be able to calculate these 3 things: Heat generated in a fuel rod at a distance ‘r’ from the center; Total Heat generated in the Reactor; the maximum temperature in the fuel and the cladding surface temperature, for a fuel rod at a distance ‘r’ from the center. The fuel used in this will be UO2 and there is a thin layer of helium that will separate the fuel from the cladding material. The user input parameters will be: the thermal neutron flux at the core, thermal conductivity of fuel, thermal conductivity of helium, thermal conductivity of the cladding, thickness of the helium layer, thickness of the cladding, diameter of the fuel pellet, fuel rod location (r), Cylindrical Reactor Size, and the fuel enrichment. For the fluid the user input will be coolant temperature and the heat transfer coefficient.
