Design, Development and Heat Transfer Analysis of Cryogenic Transfer Lines

IISc, Bangalore

  • The project focuses on designing, developing, and analyzing the heat transfer performance of cryogenic transfer lines, with extensive research on insulation materials and commercially available dimensions to optimize thermal efficiency.
  • A CFD model was validated using published research (Lye et al.), with ANSYS 2020 R2 simulations comparing outlet temperatures. A mesh-independence study and a 2D vs. 3D modeling comparison were performed to reduce computational time while maintaining accuracy.
  • Various insulation techniques, including bare tube, Polyurethane Foam (PUF), and vacuum jacket insulation, were analyzed. Simulations identified a critical insulation thickness, beyond which additional insulation increased outlet temperatures rather than improving performance.
  • A parametric study on insulation thickness provided insights for optimizing cryogenic transfer line designs, ensuring better energy efficiency and practical applicability for commercial industries.
  • Future work includes experimental validation of CFD results to enhance accuracy, with the development of a comprehensive database of optimized transfer line configurations for industrial implementation.
