Hello,
Yes, I have figured this part out that the pressure is the same after the nozzle and after the bucket (afterall, this is the theory behind impulse turbine) but currently I am looking for the pressure before the labyrinth. I used my magical MS Paint skills to draw a picture.
Yellow is...
Hello,
Yes, I have assumed all enthalpy drop (186 kJ/kg, isentropic case 206 kJ/kg -> loss 20 kJ/kg) to be in the nozzle set, but I am a little lost how to calculate the state after I have lost all kinematic energy generated with nozzle.
I highly doubt the state which counts as leakage loss in...
Hello,
Forgot to mention, this turbine is one-wheel HP turbine (impulse, Curtis wheel) so condensing / wet-% shouldn't be a problem as shouldn't exist in this only stage.
So if I assume nozzle speed ratio to be 0.95, the efficiency for the nozzle is around 0.9 (0.952 if you don't account v0)...
Hello,
I am trying to calculate the state of steam between the nozzle and impulse turbine wheel for tip and labyrinth leakage purposes for a specific steam loss model, and having some troubles with it.
Using _0 before nozzle, _1 after nozzle but before turbine blades, and _2 after turbine...
