  • TT-1 Beware of large height under nozzle with parallel-cut baffles

    January 26, 2017
    Component: Xist Applicable to: All supported versions (versions 7.3 and 8) Date posted: 4 January 2008 In cases with parallel-cut baffles, when the height under nozzle lowers the top of a tube bundle below the baffle cut, the accuracy of Xist results is reduced. In such cases, a bundle bypass path...

  • TechTip: Self-venting Nozzles in Condensers

    January 16, 2017
    Self-venting nozzles are often desired in partial or complete condensers. HTRI recommends sizing these nozzles for gravity condensate flow to produce weir-type flow. Xist® can help users size self-venting nozzles properly with warning or informative messages; however, certain criteria must be met for the software to complete the necessary calculations. Xist uses...

  • Q11-2 Simulating Nozzle Flow in Spiral Exchangers using CFD

    January 16, 2017
    Computational fluid dynamics (CFD) analysis was used to calculate the nozzle pressure drop K-values for spiral plate heat exchangers. Results of this analysis resolved the discrepancy between K-values from the Minton method and in PHE-11. The K-values from PHE-11 compared better with the CFD results in the region of Reynolds numbers...
