Design methods for reflux condensers Reflux condensers have become increasingly important to eliminate condensable organic components from plant off-gas streams and meet environmental requirements. Recognizing this need, HTRI conducted an experimental and analytical study in the late 90s to predict flooding, as well as heat transfer and pressure drop in vertical intube reflux condensers. |

The Synergy of Simulation, Experimentation and Technical Support Activities in a Research Consortium For the business of designing process heat exchangers, computational fluid dynamics (CFD) tools are still not practical for everyday use. However, in a research consortium such as HTRI, integrating advanced analysis tools like CFD with industrial-sized experimentation and then applying them to real-world technical problems provides a significant synergistic benefit to the consortium members. |
