AC-20 Side Blockage Effects on Performance of Forced-draft Air-cooled Heat Exchangers
December 21, 2022This 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...
Pattern vs Performance
July 07, 2022HTRI staff Salem Bouhairie and Syed Haq recently published an article, Pattern vs Performance, in the June issue of Hydrocarbon Engineering. This article discusses how airflow patterns within air-cooled heat exchangers degrade performance....
AC-19 Mixed Convection Heat Transfer Outside High-finned Tube Bundles in Low Airflow
June 23, 2022Modeling 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...
