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...

Simulating air-cooler header and fan performance informs physical testing plans
June 05, 2019
Salem A. Bouhairie, Senior Project Engineer, Research Both tubeside and airside behavior affect the overall performance of an air cooler. Two concerns with air-cooled heat exchanger (ACHE) operation are two-phase process-side maldistribution in headers and misrated airside fan performance. At HTRI’s Research & Technology Center (RTC), we are developing plans to...
