Experimental testing of two-phase maldistribution in air-cooler headers can lead to more effective header design
April 03, 2024
Salem Bouhairie, Group Lead, Research Air-cooled heat exchangers (ACHEs) in the oil, gas, and power industries often process two-phase fluids, and their performance is usually limited by the airside thermal transfer resistance. However, flow on the tube side can undergo phase change, such as by vapor condensation or liquid vaporization, producing...

Two-phase flow in air-cooled heat exchangers
June 10, 2020
Brandon White, Test Engineer Air-cooled heat exchangers are one of the most widely used types of heat exchangers. At times, they can experience two-phase flow separation and flow maldistribution inside their header boxes, potentially reducing process heat transfer. At HTRI’s Research & Technology Center, we are currently working on a project...

Case Study - Reducing Hot Air Recirculation around Air-cooled Heat Exchangers
April 13, 2020
Download Case Study PDF SUMMARY An engineering, procurement, and construction company needed to enhance the performance of a bank of API 661 air-cooled heat exchangers (ACHEs) at a refinery. HTRI was asked to optimize the installation of two new forced-draft ACHEs, which were to be appended to seven existing induced-draft ACHEs....
