Implication

Multi-objective optimization method improves thermal energy gain and reduces entropy generation in PFMCHEs.

Key Points

  • The optimization framework reduces pressure drop by 30-35% while enhancing thermal energy transfer, leading to better heat exchanger designs.
  • A penalization factor is used to balance solid and fluid distributions, optimizing competing goals like thermal energy gain and entropy generation.
  • Finite volume formulation facilitates accurate temperature, velocity, and pressure field calculations for various fin shapes in PFMCHEs.
  • The model examines variability in topology, showcasing how fin length affects overall performance in microchannel heat exchangers.
