Turbomachines: A Guide to Design, Selection, and Theory Turbomachinery is the heart of modern industrial infrastructure, powering everything from aviation propulsion to global energy grids. Whether you are a student exploring the fundamentals or a professional engineer seeking a reference for preliminary sizing, understanding the dynamic interaction between rotating components and flowing fluids is essential. 1. Fundamental Theory of Turbomachinery

At its core, a turbomachine is a device that transfers energy between a continuously flowing fluid and a rotating element (the rotor). This energy transfer is governed by the principles of fluid mechanics and thermodynamics.

The Euler Turbomachine Equation: Often considered the most important equation in the field, it relates the work done per unit mass to the change in the fluid's angular momentum as it passes through the rotor.

Velocity Triangles: These are critical diagnostic tools used to visualize the relationship between absolute fluid velocity, relative velocity (as seen by the moving blade), and the blade's own rotational speed.

Conservation Laws: Modern design relies on the conservation of mass (continuity), momentum (Newton’s Second Law), and energy (First Law of Thermodynamics) to predict machine performance. 2. Classification and Selection Criteria

Selecting the right turbomachine depends on the required head (energy per unit weight), discharge rate, and the properties of the working fluid. I couldn’t find a direct, publicly accessible PDF

Case Study A: High-Head Hydropower (Pelton Turbine)

• Requirement: Q = 5 m³/s, H = 500 m.
• Theory Application: Specific speed (Ns) calculation suggests a Pelton wheel (impulse turbine). Euler equation is simplified because pressure remains constant across the rotor.
• Design Challenge: Jet-to-bucket ratio and number of nozzles (typically 4-6). Bucket geometry must split the jet without causing interference.
• Selection Outcome: A horizontal-axis Pelton wheel with a rotational speed of 500 RPM, manufactured from stainless steel to resist cavitation erosion.

4.1 The Selection Matrix (Based on Specific Speed)

| Machine Type | Specific Speed (N_s) | Typical Head | Typical Flow | Applications | | :--- | :--- | :--- | :--- | :--- | | Centrifugal Pump | 100 – 800 | High | Low | Water supply, oil pipelines | | Mixed Flow Pump | 800 – 5,000 | Medium | Medium | Flood control, drainage | | Axial Flow Pump | 5,000 – 20,000 | Low | High | Circulation, cooling water | | Centrifugal Compressor | 200 – 1,000 | High (20:1 ratio) | Low | Refinery, turbochargers | | Axial Compressor | 1,500 – 5,000 | Low (1.2:1 per stage) | High | Jet engines, large gas turbines |

Step 1: Preliminary Sizing (Mean Line Design)

The mean-line (or through-flow) analysis is the first approximation. The guide provides spreadsheets and step-by-step procedures to calculate:

• Inlet and outlet blade angles
• Number of blades (using Pfleiderer’s or Stepanoff’s equations)
• Solidity ratio (chord/pitch)

2. Supercritical CO2 (sCO2) Turbomachinery

Next-generation power cycles use supercritical CO2 because of its high density, leading to incredibly compact turbines (one-tenth the size of a steam turbine for the same power). The theory requires real-gas equations of state, not ideal gas assumptions.

6. Loss models & efficiency contributors

• Profile (airfoil) losses — scale with loading and Reynolds.
• Secondary flows and endwall losses — increase with spanwise loading and blade aspect ratio.
• Tip leakage (shrouded vs unshrouded).
• Shock and wave losses (transonic/supersonic blades).
• Disc and bearing mechanical losses, tip clearance, leakage flows.
• Use empirical correlations or CFD for detailed prediction.
