In our classes about packed beds, (18 and 19), we found the T o using a simplified thermal energy balance, as well as the thermal energy generated per pellet. We made the assumption that the k of the uranium oxide and graphite were the same (2 W/m 2-K). Now assume that graphite is 5.7 W/m-K. What are the temperatures at the surface of the pellet as well as at the surface between the uranium oxide and the graphite? What is the maximum temperature? 2. Consider laminar flow in a parallel plate channel. The axis is in the center of the channel, and the width between the two plates is 2y O . Velocity and temperature profiles have the form: with units of m/s and o C respectively. Find the mean velocity and mean temperature, and plot the velocity and temperature distributions....
