After some feedback regarding using methanol as a fuel in a DIY turbocharger based turbine and more so how it affects TIT compared to common fuels JetA, Kero or propane. Also any experience anyone may have had with water/meth injection supplementing fuel to reduce TIT

Methanol would be a waste of an expensive fuel , plus you'll burn twice as much of it compared to running on kero .
With regards using water/meth flametube injection, we run into flow capacity issues of the turbine stage , if the turb stage is oversized and needs "filling out" ,there might be a reason to use it , but again , its a waste of the methanol when straight water would do the job .
Cheers

Cheers John Hi John, thanks for the quick reply. Aware of the significant increase in fuel consumption, but I have access to significant amounts of methanol. If we disregard the consumption and price from the equation how does it behave form a performance point of view with regards to mass flow and temperatures. For example being used as a gas generator and recovering power with a free turbine. Thanks Paul |

Hi Paul
It'll work OK , same as in an IC engine :-)
Cheers
