+## Validation
+
+One validation case has been performed so far, on the Ariane 5's Vulcain engine. It is hoped that more validation will be performed in the future.
+
+A key effect that needs to be investigated is nucleate boiling, and how significantly that affects the results. Test cases that use a supercritical coolant will not be susceptible to nucleate boiling, and so are better modelled by Bamboo (which currently ignores two-phase effects).

 ## Release 0.2.0
 - Refactored all code to be much more user friendly and intuitive. 
 - A generic heat exchanger solver has been implemented, which is now used for all simulations. This solver is more flexible than before, and allows for new features such as choice between co-flow or counter-flow cooling.
