Research Update: Evaluation of HTFS and HTRI Shellside Condensation Methods

Using available open literature sources and data from HTRI’s shellside condensation database, HTRI compared the predictions of horizontal shellside condensation correlations documented in HTFS™ reports and methods contained in HTRI Xchanger Suite^®. The results show that HTFS methods slightly overpredict heat transfer coefficients for pure components and poorly predict heat transfer coefficients for condensation of mixtures with and without noncondensable gases. However, HTFS methods for pressure drop outside plain tube bundles perform marginally better than current HTRI methods. We continue to evaluate HTFS methods for possible implementation in our refactored software.
