I know, but my objective was just to get a hint about the "true" answer. Is it close to 1 mm? 10 mm? 20 mm? Etc.
The thing is that we have a sensor reading the differential expansion of the turbine shaft and right now it's showing 10 mm too little according to some people but I doubt that...
Thanks Fred for your reply.
I understand it's a complicated problem and that there's a lot of unknown details. However, at the moment I'm only looking for a figure that is somewhere near the truth. The same goes for the formula I mentioned earlier, concerning the expansion due to increasing...
It's a fact that a shaft in a turbine is expanding when the temperature is increasing. A simple equation gives that the expansion can be described as: deltaX=(T1-T0)*alpha*x0, where deltaX is the expansion, T0 is the initial temperature, T1 is the final temperature and alpha is a coefficient...
