HTRI experimentally evaluated the thermal-hydraulic performance of a water-water plate-and-shell heat exchanger at the Research & Technology Center and then used the results to calibrate a solution approach through computational fluid dynamics. The tortuous flow paths through the corrugated channels of the plate pack were modeled effectively using porous media. Inertial resistance...

This report provides a comprehensive look at the turndown operation of a vertical tubeside thermosiphon reboiler (VTTR), including predictions of thermal and hydraulic performance and quantitative criteria for turndown limits. Data were collected for water, n-pentane, p-xylene, and n-pentane/p-xylene mixtures in an industrially relevant VTTR flow loop. The unit was systematically turned...
