This webinar highlights the accomplishments of HTRI Research over the past year and describes how HTRI members can benefit from these developments. We briefly discuss airside studies with our air cooler unit, vacuum condensation experiments with hydrocarbon mixtures, new phase change methods for plate heat exchangers, subcooling with shellside condensation, and more. The session updates information originally presented at the 2018 Global Conference.
This webinar will explore the use of integrated Exchanger Optimizer features in Xchanger Suite 8.0.
In an experimental, sponsored research program, HTRI investigated the thermal and hydraulic characteristics of a welded plate heat exchanger (WPHE). We conducted liquid-phase, flow boiling, and condensation experiments in a WPHE provided by Hisaka Works, Ltd.
These data, together with single-phase and phase-change data from other commercially available chevron-type plate heat exchangers, provide us a strong foundation for developing generalized heat transfer and pressure drop methods for corrugated crisscross channels.
In this presentation, we discuss our analysis of the data. We demonstrate thermal stratification of liquid flow and liquid-vapor and temperature maldistribution of horizontal flow boiling in vertical channels. Because software specific to modeling cross flow of hot and cold streams in WPHEs was not available, we used Xphe to estimate thermal predictions. Using a countercurrent arrangement—and without accounting for the impact of cross flow or maldistribution—Xphe predicts most of the data within reasonable ranges. However, the current phase-change methods in Xphe do require some improvement before they apply to all plate heat exchangers with corrugated crisscross channels.
This webinar discusses considerations and limitations in the use of single-segmental baffles. It demonstrates the impact of baffle cut and spacing in various process applications.
