TPG-2 Flow Distribution and Pressure Drop Calculations for Shellside Two-Phase Flow in Baffled Exchangers

J. W. Palen and J. Taborek

In support of the HTRI methods for two-phase flow shellside heat transfer and pressure drop described in other reports, this report provides additional information in three areas.

  1. Calculation of total shellside pressure drop, including recommendations for nozzles and end baffle spacings.
  2. Calculation of simplified Stream Analysis Method shellside flow fractions, including a comparison of single-phase and two-phase results.
  3. General design recommendations for good shellside flow distribution.

Data for two-phase flow on shellside of large exchangers are badly needed for confirmation, but in lieu of data the recommendations in this report are considered to represent the best HTRI estimations at this time.
