Flow-Induced Vibrations: Understanding Fluid Dynamics in Solar Shading Design

Levolux – a leading UK-based innovator in solar shading and screening systems, approached Xi Engineering Consultants to validate the aerodynamic and structural performance of a new solar shading louvre array. This system was designed to enhance energy efficiency and comfort by managing solar exposure but required precise engineering validation to ensure structural reliability and noise control.

CFD Drag and Pressure Drop Analysis for Optimised Solar Shading Systems

Stage 1 

Xi Engineering used Computational Fluid Dynamics (CFD) simulations to assess wind forces on the louvres, calculating drag coefficients and pressure drops at varying angles. This detailed aerodynamic analysis was crucial for optimising the design and ensuring the solar shading system could withstand wind loads while maintaining operational efficiency.

Modal and Vibration Analysis for Structural Integrity in Wind-Loaded Systems

Stage 2

Through modal analysis, Xi identified potential resonance frequencies within the louvre structure. This analysis provided key insights into how the system would behave under different wind conditions, ensuring that the louvres would not experience damaging vibrations that could compromise structural integrity.

Vortex Shedding and Its Impact on Solar Louvres: A CFD-Based Approach

Stage 3:

Vortex shedding is a common issue for large, wind-exposed structures. Xi Engineering used advanced CFD tools to simulate these effects and evaluate the risk of resonance-induced vibrations. By determining the vortex shedding frequency and comparing it to the system's natural frequencies, Xi ensured that the design would not be susceptible to performance failures.

Noise Reduction Through Acoustic and Vibration Control in Urban Installations

Stage 4:

To prevent disruptive noise, Xi Engineering performed an in-depth acoustic analysis. The team calculated sound pressure levels generated by wind interactions with the louvres, addressing potential noise issues and ensuring compliance with urban noise regulations, a crucial factor for installations in densely populated areas.

Key Benefits of Digital Twin Technology for Building Performance and Management

In addition to CFD and structural analysis, Xi Engineering’s Digital Twin technology capabilities can significantly enhance project outcomes. By creating a digital replicas Digital Twins allow for real-time monitoring, performance optimisation, and predictive maintenance. This enables clients to extend the lifespan of their assets and reduce long-term operating costs by making data-driven decisions, ensuring their investments remain reliable and efficient over time.

Commercial Benefits to the Client

Levolux benefited from Xi Engineering’s services in several key ways:

  • Structural optimisation reduced the risk of operational disruptions due to wind-induced vibrations.
  • Cost savings were achieved by validating the design early, avoiding the need for costly structural modifications later.
  • Enhanced client confidence through compliance with noise regulations and improved overall system performance.
