velocity triangle. 4.5 SLIP FACTOR From the above discussion, it may be seen that there is no assurance that the actual ﬂuid will follow the blade shape and leave the compressor in a radial direction. 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

Let us first understand here the various nomenclatures that we are using here. u1 = Mean blade velocity at inlet = πD1N/60. u2 = Mean blade velocity at outlet = πD2N/60. V1 = Absolute velocity of air at inlet to rotor or impeller. Figure 16.18 shows velocity triangles for one stage of the compressor. Air approaches rotor blade with absolute velocity V 1 at an angle α 1 to the axial direction. Combining V 1 with blade velocity u 1 gives relative velocity V r1 at inlet, inclined at angle β 1 with the direction of motion.

Static and stagnation values of pressure and enthalpy in the absolute and relative systems are also shown. The change in magnitude of radial velocity. a velocity triangle or. Performance characteristics for high speed machines such as compressor and turbines are also discussed in the chapter.

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.

The vector nature of velocity is utilized in the triangles, and the most basic form of a velocity triangle consists of the tangential velocity, the absolute velocity and the relative velocity of the fluid making up three sides of the triangle. The velocity triangle is the vectorial representation of kinematic movement.

Centrifugal compressors, sometimes called radial compressors, are a sub-class of dynamic axisymmetric work-absorbing turbomachinery.. They achieve a pressure rise by adding kinetic energy/velocity to a continuous flow of fluid through the rotor or impeller.
