Turbine / Compressor Educational Series
The following page breaks down the various definitions needed to understand and learn the dynamics and ideal operating conditions of turbine and compressor system environments. There are four categories of definitions in this lesson: thermodynamics, fluid dynamics, mechanical engineering / design, and turbomachinery operations.
1. Thermodynamics
At the heart of turbomachinery lies the application of thermodynamic principles to understand how energy is transferred between fluids and mechanical systems. To fully comprehend how compressors and turbines work, these key concepts come into play:
- Polytropic Process and Isentropic Process are both idealized processes describing how a gas is compressed or expanded. An isentropic process is an ideal case where no heat is transferred, and the system is 100% efficient. In contrast, the polytropic process accounts for real-world heat transfer and inefficiencies, making it a more accurate measure for real systems.
- Polytropic Efficiency measures the efficiency of compressors and turbines when real-world heat losses and energy transfer are considered. In practice, it tells us how close the system is to operating as efficiently as possible.
- Stagnation Temperature and Stagnation Pressure are fundamental in assessing the total energy of a fluid, accounting for both its kinetic energy (due to its motion) and its internal energy. These properties are crucial for evaluating a machine’s overall performance.
- Enthalpy (H) and Stagnation Enthalpy (h₀) further quantify the energy in a system. They describe the total energy available in a fluid, including both internal energy and the energy required to push the fluid through its environment.
What can be learned:
By understanding the thermodynamic terms, we learn how to analyze the energy interactions in turbines and compressors. These concepts provide the tools to calculate how efficiently energy is converted and how changes in pressure, temperature, and entropy affect the performance of turbomachinery.
2. Fluid Dynamics
Fluid dynamics focuses on how fluids move through a system and how their properties change under varying conditions:
- Flow Coefficient (ϕ) is a key parameter in understanding how much fluid is moving through a machine relative to its size and rotational speed. A higher flow coefficient typically means more fluid is being moved, which affects the machine's design.
- Axial Velocity and Axial Velocity Profile describe the movement of fluids along the axis of a turbine or compressor. These velocities help determine how work is distributed across the length of the machine, influencing the efficiency of energy transfer.
- Compressibility (Z) helps us account for the non-ideal behavior of gases as they are compressed, which is essential when dealing with high-pressure systems like turbines.
- Choked Flow is a critical phenomenon that occurs when the mass flow rate through a nozzle or compressor reaches a maximum, regardless of downstream pressure. Understanding when choked flow occurs helps prevent operational issues.
- Diffusion Factor (DF) helps predict stalling conditions by measuring how much a fluid decelerates in a compressor stage. When the diffusion factor is too high, flow separation can occur, leading to stall, a condition that causes performance issues.
What can be learned:
By mastering fluid dynamics, we can predict and optimize how fluids behave in different sections of a compressor or turbine. This knowledge allows for the design of efficient, stable machines that can handle a wide range of operating conditions, such as changes in pressure or velocity.
3. Mechanical Engineering / Design
The physical construction of compressors and turbines is critical for ensuring that they operate reliably and efficiently:
- Multistage Compressor: Compressors often work across multiple stages, where gas is compressed gradually in steps, reducing energy losses. Understanding how each stage contributes to overall compression is vital.
- Labyrinth Seal and Squeeze Film Damper are key components used to minimize fluid leakage and control vibrations in turbomachinery, improving reliability.
- Radial Bearing, Journal Bearing, and Tilting Pad Bearing are essential for supporting rotating components and reducing friction. Their correct design and selection are crucial for reducing wear and ensuring smooth operation.
- Critical Speed is an important consideration in machine design. At this speed, vibrations can amplify and cause damage. Proper balancing and bearing selection help prevent machines from reaching this dangerous resonance.
- Babbitt Coating: Bearings are often lined with this soft metal to reduce friction and prolong machine life.
What can be learned:
Understanding mechanical design concepts helps in ensuring that compressors and turbines are built to last. By learning how to control friction, vibration, and fluid leakage, engineers can optimize machine performance and prevent failures.
4. Turbomachinery Operations
These terms describe the behavior of machines under different conditions and help engineers optimize their performance:
- Stage Pressure Ratio: Describes how much compression happens at each stage of a multistage compressor. This ratio indicates how effectively the machine increases pressure step by step.
- Stage Loading Factor (ψ): Represents the energy imparted to the fluid in each stage, providing a way to calculate how much work is being done in the system.
- Surge and Stall: Both are dangerous operational conditions. Surge occurs when the compressor’s flow reverses, while stall happens when airflow separates from the blades, leading to a loss in efficiency. Engineers use terms like Surge Margin and Diffusion Factor to predict and prevent these occurrences.
- Stage Matching: A critical operation in multistage compressors where each stage is fine-tuned to ensure that all stages work together efficiently. Without stage matching, some stages may experience stall or choke conditions.
