Flow Analysis and Geometry Optimization

Understanding fluid flow behavior and topology changes can be critical in addressing specific component or system challenges and identifying opportunities for improvement. Leveraging a variety of tools and approaches, the OTS team can model and analyze heat exchanger and system level fluid flows and optimize surfaces, shapes and passages to achieve greater performance.

Flow Analysis and Geometry Optimization
  • Fin Design

    Knowing what improvements and changes to incorporate for a new fin design is critical when considering a capital investment for a new fin die. OTS R&D has worked with multiple teams to identify new fin designs for their application, assessing a wide range of options including the impacts of tube diameter, fin thickness, spacing, slits and louver enhancements, and other novel features.

  • Airflow Analysis and Designing for Maldistribution

    In most systems, coils are installed in small boxes, air has to flow through narrow channels or around sharp bends and there is never uniform flow. Understanding the severity and variation of maldistribution can be critical in assessing appropriate redesign choices to improve performance and reduce noise. Our team is experienced at evaluating unique airflow patterns and working with you to identify opportunities for improvement, whether that is exploring fan and enclosure changes to streamline flow, or coil changes to work with the given maldistribution.

  • Correlation dev

    Correlation Development

    One way to significantly improve the accuracy of heat exchanger models is to develop a specific and comprehensive correlation accounting for the range of parameters accounted for in the design. While this is often done experimentally with strategic testing, it can also be accomplished by leveraging a CFD-developed correlation. We’ve proven this method on multiple occasions and find it offers significant benefit in relation to the low computation and experimental cost.
