Boiling Heat Transfer

Robust and scalable cladding surfaces to enhance boiling heat transfer performance in LWR conditions

Synopsis of project aims:

This project intends to develop resilient and effective micropillars texturing of fuel cladding material with ideal surface that has

  1. The highest possible critical heat flux (CHF) limit in LWR conditions.
  2. The highest possible heat transfer coefficient in LWR normal operating conditions, including:
    • single-phase liquid forced convection,
    • subcooled nucleate boiling, and
    • saturated boiling (across different flow regimes, e.g., slug, churn, and annular flow) regimes
  3. The highest possible Leidenfrost Point Temperature (LPT) in both droplet impingement and reflooding scenarios.
