NE 321 Nuclear Heat Transport Summer 2020 Homework- 5 Due:    Q1) Derive the 2D unsteady heat conduction equation in Cartesian coordinates with heat generation and variable K. Q2) Derive the 3D unsteady heat conduction equation in Cartesian coordinates with heat generation and variable K. [Please submit the answer using text so I can just copy and paste it, thank you] [The book name for the two homeworks is a Nuclear Heat Transport ] Homework- 6 Due date: The 3D, unsteady thermal heat conduction equation is given by: ρC where, ρ is the fuel density, C is the specific heat of the fuel, K is the thermal conductivity of the fuel. K is defined from the Fourier law: Where q is the rate of thermal energy transfer, and A is the area normal to the direction "n" of heat transfer. For constant K, the equation reads: Divide both sides by K, and define the thermal diffusivity α α   =      The equation becomes: Q) For the metric system of units, what is the unit of the thermal diffusivity α ?
