Figure 16.14 shows velocity triangle for radial blades. Dotted lined diagram represents ideal conditions while full lined diagram represents actual conditions. In actual practice, when impeller has finite number of blades, fluid is trapped between the impeller vanes due to its inertia and the fluid is reluctant to flow over the impeller.
13. 2.2 Impeller velocity triangles [2] . Centrifugal- compressor schematic and velocity triangles. From figure (a) in previous slide, fluid enters the rotor with an absolute velocity that is completely radial In a centrifugal compressor, energy is transferred from a set of rotating impeller blades to the gas. The designation “centrifugal” implies that the gas flow is radial, a) Axial Inlet Guide Vane b) Impeller Inlet c) Impeller Exit. Fig. 1: Velocity Triangles in a Centrifugal Compressor.
Thus, it is convenient to define a slip factor s as: s¼ C w2 U 2 ð4:1Þ Figure 4.6 shows the phenomenon of fluid slip with respect to a learn the principle of making velocity triangles of centrifugal compressor.Special thanks to poornima university family It is often assumed that the axial velocity component remains constant through the stage. From this condition we get, c x = c 1 cos α 1 = c 2 cos α 2:= w 2 cos β 2 = c 3 cos α 3 = w 3 cos α 3 Also, for constant axial velocity yields a useful relation: . tan α 2 + tan α 3 = tan β 2 + tan β 3. Single impulse stage. A single-stage impulse turbine is shown in Figure Air enters the compressor at stagnation temperature of 20oC and 1 bar. If the impeller has radial blades at the exit such that the radial velocity at the exit is 136 m/s and the isentropic efficiency of the compressor is 0.82. Draw the velocity triangle at the exit of the impeller and calculate slip.
Thus, the inlet velocity triangle and the main geometry dimensions can be determined from the above parameters. The rotor exit velocity triangle can be found out from the conventional coefficient which are discussed and recommended by the Aungier. The ratio of meridional velocity ratio is: à5 à4 =1+5(𝑏4 4) 2 :12 ;

So, v1 = vr1, vw1 = 0 and α1= 90ᵒ. According to the practical test from Imperial College of Engineering, impeller inlet velocity V1 is less than at eye due to the rise in static pressure. From inlet velocity triangle relative velocity is, = …
