Consider Problem 17.13. Now consider the overall heat transfer coefficient (U) to be 100 W/m 2 C.
Question:
Consider Problem 17.13. Now consider the overall heat transfer coefficient (U) to be 100 W/m2°C. Simulate the same changes as before. Did you notice any difference in the transient profiles in comparison to what you obtained before? Why or why not?
Problem 17.13
Consider Figure E17.6(a), in which the overall heat transfer coefficient (U) is assumed to be 25 W/m °C. It can be noted that in Figures E17.6(b) and E17.6(c)(b), the transients in exit temperature and CO concentration appear to be negligible. Now increase the flowrate of benzene to 0.01 kmol/h, while keeping the flowrate of air constant. Simultaneously increase the temperature of air to 520°C. Did you notice any difference in the transient profile of temperature and benzene and CO concentration at the exit of the reactor compared to what is obtained in Example 17.6? Why or why not?
