SubscriberHow can I calculate the Nusselt number for pulsating flow? I'm just working on a simple pipe. Water will enter at 2000 Reynolds numbers and a frequency of 1, and I need to calculate the outlet temperature. I also need the Nusselt number and pressure change. I've imported the mass flow rate data from Excel, and I think there's nothing wrong with the graph. But I can't calculate the Nusselt number. What should I do?
