CS-17 Comparison of HTFS and HTRI Horizontal Shellside Condensation Methods
A comparative study was performed using horizontal shellside condensation correlations documented in HTFS reports and methods contained in HTRI Xchanger Suite®. Because the original data underlying the HTFS methods were unavailable, this study used open literature sources and data from HTRI’s shellside condensation database. While HTFS methods slightly overpredict the heat transfer coefficients for pure components, they poorly predict the heat transfer coefficients for situations involving condensation of mixtures with and without noncondensable gases. HTFS methods for pressure drop outside plain tube bundles perform marginally better than current HTRI methods.
