• 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...
