Available in PDF, EPUB and Kindle. Book excerpt: An experimental study was made to determine the quantitative accuracy of the hydraulic analogy when applied to subsonic internal flows such as exist in pure fluid elements. The analogy is based upon the correspondence between density and depth (or pressure and depth squared) when the Mach number and Froude number are equal. Experiments were run in air and in water on geometrically similar nonsymmetrical flow dividers. A factor was used to correct for the difference in apparent specific heat ratios k. (Apparent k = 2 for hydraulic flow, k = 1.4 for air flow.) After this correction was made, the data correlated to within three percent. The Reynolds number for the water flow varied from about 1,500 to 4,000 and, for the air flow, from 17,000 to 100,000. The good correlation, even though some of the water data was taken in apparently laminar flow, indicated that inertial effects predominated over viscous effects. This was because the fluid was essentially at rest before it entered the flow divider. The geometry was characterized by sharp angles and relatively short flow lengths so that convective acceleration and separation zones dominated the flow and established patterns of velocity distribution did not have a chance to completely develop.

Available in PDF, EPUB and Kindle. Book excerpt: The blade life estimation is a multifaceted technology, involving free and forced vibration forces, that lead to the determination of steady and dynamic stresses at different critical speeds during the startup and shutdown procedures, as well as in the operational speed range. Propagation and unstable fracture are described with practical examples to estimate blade life.

Available in PDF, EPUB and Kindle. Book excerpt: Fatigue Failures Of Blades Is One Of The Most Vexing Problems Of Turbomachine Manufacturers, Ever Since The Steam Turbine Became The Main Stay For Power Generating Equipment And Gas Turbines Are Increasingly Used In The Air Transport. The Problem Is Very Complex, Involving The Excitation Due To Aerodynamic Stage Interaction; Damping Due To Material Deformation, Friction At Slip Surfaces And Aerodynamic Damping; Vibration Of An Asymmetric Aerofoil Tapered Along Its Length And Mounted On A Rotating Disc At A Stagger Angle. The Problem Is Also Governed By Heat Transfer Analysis And Thermal Stresses.His Book Deals With A Basic Understanding Of Free Vibratory Behaviour Of Turbine Blades- Free Standing, Packetted, And Bladed-Discs. The Analysis Is Based On Continuous And Discrete Models Using Energy Principles And Finite Element Techniques. A Clear Understanding Of The Interference Phenomenon In A Thin Cambered Airfoil Stage In Subsonic Flow Is Presented To Determine The Nonsteady Excitation Forces Acting On The Blades. A Comprehensive Treatment On The Blade Damping Phenomenon That Occurs In Turbines Is Given. The Nonlinear Damping Models Account For Material Damping And Friction Damping As A Function Of Rotational Speed For Each Mode. Resonant Response Calculation Procedures For The Steadily Running As Well As Accelerating Blades Are Given.Cumulative Damage Calculations Are Then Outlined For Fatigue Life Estimation Of Turbomachine Blades. The Book Also Deals With Heat Transfer Analysis And Thermal Stress Calculations Which Help In A Comprehensive Understanding Of The Blade Problems.
