AC-20 Side Blockage Effects on Performance of Forced-draft Air-cooled Heat Exchangers
December 21, 2022
This report details a numerical study investigating the effects of blockages on the performance of an air-cooled heat exchanger. A high-fidelity computational fluid dynamics (CFD) model of HTRI’s Air-cooled Unit (ACU) is simulated and calibrated using experimental data from the unit. The validated CFD model is used to simulate five arrangements...

AC-19 Mixed Convection Heat Transfer Outside High-finned Tube Bundles in Low Airflow
June 23, 2022
Modeling natural-draft air coolers requires accurate prediction of airside heat transfer coefficients at low airflow rates. HTRI has collected additional data from the Air-cooled Unit (ACU) to develop a correlation for mixed convection that predicts low airflow heat transfer. The improved correlation, based on Rayleigh and Reynolds numbers, results in an...
