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.
Please answer the question and provide explanation why they are correct or incorrect.
A steel tube having k =46W/m•C has an inside diameter of 3.0 cm and a tube wall thickness of 2 mm is covered with a 3-cm layer of asbestos insulation [k =0.2 WN/m•C]. A fluid flows maintains inside tube surface temperature 223•C while the outside surface insulation temperature is 57 C. Calculate the heat lost by the tube per meter of length and what in the tube-insulator interface temperature?
To maximize production and minimize pumping costs, crude oil is heated to reduce its viscosity during transportation from a production field. (1) Consider a pipe-in-pipe configuration consisting of concentric steel tubes with an intervening insulating material. The inner tube is used to transport warm crude oil through cold ocean water. The inner steel pipe (k, = 45 W/m-K) has an inside diameter of D₁, 1 = 150 mm and wall thickness t; = 20 mm while the outer steel pipe has an inside diameter of D₁,2 = 250 mm and wall thickness to = 1;. Determine the maximum allowable crude oil temperature to ensure the polyurethane foam insulation (k = 0.055 W/m-K) between the two pipes does not exceed its maximum service temperature of 7p,max = 70°C. The ocean water is at T, = -5°C and provides an external convection heat transfer coefficient of h, = 500 W/m²K. The convection coefficient associated with the flowing crude oil is h; = 450 W/m².K. (2) It is proposed to enhance the performance of the…
