Vibration analysis has been added for hairpin exchangers in Xhpe.New logic for determining baffle spacing, number, and placement has been added for hairpin exchangers in Xhpe.New logic was added for determining flow areas under nozzles located at or beyond U-bends in Xist.The shellside condensation heat transfer coefficients have been reviewed and updated to resolve a few discrepancies between code implementation and the Design Manual and research reports.The Fair flow regime map has been added for vertical tubeside boiling in Xist.New shellside flow regime boundary correlation has been added to predict potential for phase separation for horizontal exchangers with boiling.Shellside reflux condenser flooding methods were refined to better predict flooding potential in critical areas of the exchanger.

Shellside convective boiling heat transfer correlations have been revised for TEMA type F, G, and H shells.Updates were made to the shellside heat transfer coefficients and pressure drop for un-baffled exchangers.Tubeside mist flow heat transfer correlations are now available for falling film evaporators in Xist.New pressure drop methods have been implemented for U-tube bends in Xist.New heat transfer and hydraulic methods have been implemented in Xist to handle kettle bundles partially submerged in liquid.The issue of calculated pressure drops exceeding operating pressure in Xist, Xhpe, Xjpe, and Xace has been mitigated by limiting local pressures in each increment to a low limit, which allows calculations to continue and provide some answer.Initial heat load guess and convergence logic was enhanced to improve execution speed in Xist, Xhpe, and Xjpe.We added an option to specify an initial heat load estimate for simulation calculations in Xist, Xhpe, and Xjpe to speed execution and improve chances of convergence.This release includes new features and updates to programs across the entire Xchanger Suite line.
