At Western Spring Manufacturing, we take pride in our ability to produce high-quality custom springs and wire forms tailored to meet the unique needs of our clients. One of our specialties is manufacturing coiled or formed turbulators, essential components in many industrial applications, particularly for enhancing heat transfer and pressure drop.
Made primarily from brass and other non-corrosive materials, these turbulators play a crucial role in enhancing the efficiency and performance of systems across various industries.
In this resource, we will go through what coiled turbulators are, their applications, and why Western Spring Manufacturing should be your go-to source for custom turbulator solutions.
What Are Coiled Spring Turbulators?
Coiled turbulators are spiral-shaped devices designed to be inserted into tubes or channels to disrupt the flow of fluid or gas. This disruption, or turbulence, enhances heat transfer and improves efficiency in systems such as heat exchangers, condensers, and boilers.
Coiled turbulators generate a wave-like motion that directs fluid energy up and down rather than creating a spinning effect. This movement pushes the fluid toward the tube walls, disrupting the boundary layer and enhancing heat transfer efficiency.
Unlike straight turbulators, coiled turbulators are specifically engineered to fit within round tubes, making them ideal for applications where space is limited, and heat transfer enhancement is crucial.
By increasing the surface area in contact with the fluid and causing turbulence, these coils promote more uniform heat distribution and prevent hotspots, which can lead to system failures or decreased efficiency. At Western Spring Manufacturing, we understand the intricacies of these applications and offer custom coiled spring turbulators precisely designed to meet your specifications.
Heat Transfer Coefficient Increase
- Impact: Turbulators can significantly increase the convective heat transfer coefficient (h) within a tube or channel. The heat transfer coefficient is a measure of the thermal conductivity between the tube wall and the fluid.
- Typical Increase: Depending on the type of turbulator, the increase in the heat transfer coefficient can range from 20% to over 200% compared to smooth tubes. For example, coiled turbulators can increase the heat transfer coefficient by 50% to 100% in many applications.
Nusselt Number Enhancement
- Definition: The Nusselt number (Nu) is a dimensionless number that represents the ratio of convective to conductive heat transfer across the boundary layer. Higher Nusselt numbers indicate more efficient convective heat transfer.
- Effect of Turbulators: The presence of turbulators can increase the Nusselt number significantly. Studies show that Nusselt numbers can increase by 1.5 to 3 times with the use of turbulators, depending on the design and operating conditions.
Pressure Drop Considerations
- Trade-Off: While turbulators enhance heat transfer, they also cause an increase in pressure drop due to the induced turbulence. This can lead to higher pumping costs and energy consumption.
- Pressure Drop Data: The increase in pressure drop can range from 10% to 100% depending on the turbulator design and flow conditions. This is an important consideration when designing systems with turbulators to balance heat transfer efficiency with energy costs.
Performance Ratios (Heat Transfer Enhancement vs. Pressure Drop)
- Thermal-Hydraulic Performance: The thermal-hydraulic performance of a turbulator can be evaluated using a performance ratio, which compares the relative increase in heat transfer to the increase in pressure drop. A ratio greater than 1 indicates that the enhancement in heat transfer is more significant than the increase in pressure drop, making the use of turbulators beneficial.
- Typical Ratios: For well-designed turbulators, performance ratios are often between 1.1 and 2.0, meaning that the enhancement in heat transfer outweighs the additional pressure drop.
Importance of Material Selection
Choosing the right material for coiled spring turbulators is vital to their performance and longevity. While brass is typically the material of choice, below is a full list of metals used by Western Spring to produce custom turbulator coils.
1. Brass
- Properties: Good corrosion resistance, high thermal conductivity, and excellent formability.
- Applications: Commonly used in heat exchangers and HVAC systems due to its thermal conductivity and resistance to corrosion in moist environments.
2. Stainless Steel
- Properties: Excellent corrosion resistance, high strength, and good temperature resistance.
- Applications: Ideal for use in harsh environments, including those exposed to high temperatures, corrosive substances, and industrial processes, where heat transfer performance is critical. Commonly used in oil and gas, chemical processing, and food and beverage industries.
3. Copper
- Properties: Superior thermal conductivity and good corrosion resistance make these materials ideal for use in tube heat exchangers.
- Applications: Used in applications where efficient heat transfer is critical, such as in electronics cooling systems, radiators, and HVAC units.
4. Aluminum
- Properties: Lightweight, good thermal conductivity, and resistance to corrosion.
- Applications: Often used in automotive and aerospace applications where weight reduction is important without compromising heat transfer efficiency.
5. Carbon Steel
- Properties: High strength and durability, but lower corrosion resistance compared to stainless steel and brass, can affect the heat transfer performance in specific applications.
- Applications: Suitable for applications where high strength is needed, but exposure to corrosive environments is minimal. Commonly used in certain types of boilers and industrial equipment.
6. Titanium
- Properties: Extremely high strength-to-weight ratio, excellent corrosion resistance, and good thermal conductivity.
- Applications: Used in highly corrosive environments, such as marine and chemical processing industries, and in applications where weight is a critical factor, such as aerospace.
7. Nickel Alloys (e.g., Inconel, Monel)
- Properties: Exceptional resistance to corrosion, oxidation, and high temperatures.
- Applications: Ideal for extreme environments, including chemical processing, oil and gas extraction, and aerospace, where both high temperature and corrosion resistance are required.
Each of these materials can be selected based on the specific needs of the application, considering factors such as operating conditions, desired lifespan, maintenance requirements, cost, and heat transfer and pressure drop.
