Reynolds number in heat transfer coefficient

In Bell's PhD thesis, p. 146, eq. 5.27, the Reynolds number is defined in a way that differs from the code in PDSim/scroll/core.py in the heat_transfer_coefficient() function. The difference is a factor 2. Which one is correct?

Thanks in advance for your comment, Best, Guillaume

It looks to me that the typo is in pdsim. Good catch!
