(Refer Slide Time: 09:39) Here, we had already discussed this in the last class. Let me, again quickly explain the construction of a 90 degree IFR turbine. We have volute or a scroll, which sort of acts like (( )) chamber, through which the flow enters stagnation chamber here, where the flow is stagnant and then that gets accelerated through the nozzle blades. So, these are the nozzle blades. Nozzle exit station is denoted by station two. The flow then passes through the rotor blades or the impeller and exits at station three before going into the diffuser, which is the exit of the diffuser denoted by station four. You can see that, as I mention that is very similar to centrifugal turbine, a centrifugal compressor. In that case, of course, the velocity, the flow direction is the other way round. It is reverse the flow, actually proceeds in this direction. And, instead of nozzle blades, we have diffuser vanes. And therefore, this aerofoil orientation will also be the reverse. Let us look at the velocity triangles for this case. We normally have V 2 which is entering the rotor radically. So, the nozzle flow leaves relative velocity; entering nozzle is in the 90 degrees and C 2 is at an angle of alpha 2. In this case, it is given as 72 degrees. So, alpha 2 in this particular case is 72 degrees. U 2 is the blade speed at the station, that is, station two. Now, as the flow leaves the rotor, the absolute velocity leaving the rotor is axial. Under design condition, relative velocity that an angle of beta 3 with the acceleration, that is, B 3 and U 3 is the rotor speed at station three. So, this is typical inward flow radial turbinePDF Image | Turbomachinery Aerodyanmics
