Development of Reduced-Order Maps of Heat Exchanger Performance for Aerodynamic Applications

In this report heat exchangers (HX) for single-phase and two-phase problems are modeled under a variety of conditions with the goal of assessing and modifying simplified models suitable for iterative design and optimization applications. Reference models are developed for two relevant configurations to allow for development of reduced order approaches. Corrections to adapt and improve existing frameworks are introduced and compared to references under a range of conditions to determine applicability for engine cycles of interest.
