Overview

Experimental and numerical study demonstrates over 50% reductions in size and pressure drop in finless heat exchangers, indicating major efficiency gains through additive manufacturing.

Key Points

Evaluate the thermal-hydraulic performance of small finless tubes and optimize their shape using automated numerical simulations and additive manufacturing to outperform microchannel heat exchangers.
Conducted numerical analyses on fin effectiveness across small tube characteristic lengths.
Implemented shape optimization leveraging automated computational fluid dynamics (CFD) and approximation-assisted optimization techniques.
Fabricated and experimentally tested a metal 3D-printed prototype (NTHX-001) to validate the computational predictions.
Optimized designs demonstrated greater than 50% reductions in size, material volume, and pressure drop relative to baseline microchannel heat exchangers.
Experimental testing of the 3D-printed prototype matched numerical simulations within less than 5% for capacity, 10% for air heat transfer coefficient, and 15% for air pressure drop.
