4 Technologies That Can Improve Turbomachinery Efficiency

Turbomachinery plays a significant role in power generation and other mechanical applications. Generally, these machines are designed to use the transfer of energy between fluid and a rotor to perform a desired task.

They are broadly divided into two categories. A category is designed to produce power primarily. Typical examples include steam turbines, gas turbines, and hydraulic turbines. These turbines convert thermal, or mechanical, energy into electricity.

The other category is designed to increase the total pressure of the working fluid by consuming power. Typical examples include compressors, pumps, and fans. Compressors, for instance, are applied to tasks like inflating tires.

For industries that heavily depend on turbomachinery for their business production, it can be expensive to operate the machines. However, with proper optimization offered by reputable experts such as CCC Global consultants, the cost can be significantly reduced.

These experts deploy special technologies to optimize processes and improve turbomachinery efficiency. This means the machine will be able to convert more energy into useful work.

More efficient turbomachinery will consume less energy and have lower operating costs.

Factors influencing the performance of turbomachinery

The performance of the turbomachinery is affected by three main factors:


  • Compressor and turbine design: The shape of the blade, size, and material used in making the compressor and turbine all significantly impact the performance and efficiency of turbomachines.
  • Component sizing: The total size of the compressor and turbine will affect the mass flow rate and, invariably, the power output of the machine. The number of stages in the compressor and turbine will also determine the possible pressure ratio and the overall efficiency.
  • Clearance and friction: The lesser the friction between the rotating and stationary parts of the turbomachines, the better the performance and efficiency.

Operating conditions

  • Fluid properties: Various fluids are used in turbomachinery, including air, water, steam, gas, or liquid. The type of fluid handled by the system, its temperature, pressure, and density will affect its performance.
  • Pressure ratio: The higher the pressure ratio across the compressor, the better the power produced.
  • Speed: The rotational speed of the machinery can affect its efficiency and overall power output. However, there are optimal operating speeds for peak performance. This means inappropriate rotational speed can cause issues like blade stress.

External factors

  • Presence of particles: The presence of particles such as dust and sand in the fluid can cause erosion and damage to the blades, thereby resulting in performance degradation. Understanding the impact of the contamination can help in predicting erosion rates and identifying the appropriate time to change the blades.
  • Ambient conditions: Air density and pressure can affect performance. High ambient temperatures can reduce air density, while high altitudes can lower air pressure.
    Optimizing these factors can help engineers achieve fantastic turbomachinery performance and efficiency.

Optimizing turbomachinery with technologies

Turbomachinery efficiency is the measure of how well it converts energy from one form to another.
The efficiency of turbines, for instance, refers to how effectively they extract energy from a moving fluid, while the efficiency of compressors measures how well they add energy to a fluid.

Engineers can leverage the capacity of certain technologies to improve turbomachinery efficiency. They include:

1. Computational fluid dynamics

Computational Fluid Dynamics (CFD) has played a significant role in the design of turbomachinery for many years.

Turbomachinery are often faced with internal and external fluid flow problems. To significantly reduce the problem and ensure efficiency, turbomachine manufacturers usually use CFD to simulate their designs and analyze possible usage scenarios to decide on the best way to make the machine or its parts, such as blades, for optimal efficiency.

2. Additive manufacturing

Additive manufacturing, also known as 3D printing, is the use of 3D model data to guide hardware to deposit layer by layer to create a 3D object.

3D printing is applied in turbomachinery to make functional components that may be difficult to manufacture using traditional techniques.

These well-fitted components can reduce energy loss in the turbomachinery and improve efficiency.

3. Active flow control

Active flow control (AFC) is designed to regulate the flow of fluid through turbomachinery. The proper use of the AFC can help tackle issues of leakage, which may affect performance and efficiency.

There are also modern control systems that can optimize the flow for different operating conditions in the machine to ensure peak efficiency.

4. Genetic algorithms

Genetic algorithms (GA) help engineers produce the most functional components to solve a specific issue in a turbomachinery.

Engineers input a set of parameters into the genetic algorithm. The software, like the process of natural selection, filters initial designs to recommend the perfect design for optimal performance and efficiency. Such designs may recommend a certain blade angle, thickness, and other geometric features. GA subsequently helps achieve designs with better performance compared to their predecessors or those currently available in the market.
