    diagnostic methods. Correcting the seals enabled the space shuttle main engine high-pressure fuel turbopump (SSME HPFTP) to operate successfully. Keywords: Turbomachine, seals, dynamics, antiswirl, CFD, models, fluid dynamic forces, rotor/ stator clearances Introduction Operating turbomachines by nature are unsteady systems. 5 Steam Turbines Problem 1 Make an observation that out of the 10 solved examples and the 8 exercise problems of this chapter, only 4 problems required the reference to the Mollier Diagram (enthalpy–entropy chart for steam). Locate these four problems. Then, take a Mollier diagram and mark all the four.

EXAMPLE: SEE SECTION FROM H&P • Draw velocity triangles assuming that ωr = 2 times the axial velocity w (w = constant) a b c 3. Centrifugal pumps are turbomachines which are used to transport fluids. The rotation of the pump impeller generates centrifugal forces. These forces are used to deliver the water. The experimental unit provides the basic experiments to get to know the operating behaviour and the important characteristic variables of centrifugal pumps. There are different types of turbomachines. They can be classified as: 1. Turbomachines in which (i) work is done by the fluid and (ii) work is done on the fluid. 2. Turbomachines in which fluid moves through the rotating member in axial direction with no radial movement of the streamlines.

      Preface to the first edition This text outlines the fluid and thermodynamic principles that apply to all classes of turbomachines, and the material has been presented in a unified way. The approach has been used with successive groups of final year mechanical engineering students. who have helped with the development of the ideas outlined. ♥ Book Title: Turbomachinery ♣ Name Author: Rama S.R.
