  • BG1-16 Shellside Longitudinal Liquid-phase and Flow Boiling Heat Transfer for Horizontal Plain Tube Bundles

    August 01, 2017
    This report discusses liquid-phase and flow boiling data collected on the shell side of a horizontal, nonbaffled plain tube bundle. Using these and other HTRI data, we evaluated heat transfer predictions from HTRI Xchanger Suite 7.3 and modified our methods. Fluid temperature measurements around the bundle demonstrate thermal stratification of liquid...

  • STG-21 Computational Simulation of Fluid Flow, Heat Transfer, and Temperature-induced Mechanical Stress in a Shell-and-tube Heat Exchanger

    July 21, 2017
    We completed a multiphysics computational simulation of a shell-and-tube exchanger, where simultaneous fluid flow and heat transfer of both fluid streams occurred. Temperature-induced mechanical stress also acted on the solid structures. A weak coupling of a finite-volume CFD Navier-Stokes model with a finite-element computational solid mechanics model underlies the multiphysics simulation....

  • Research Update: Identifying Ledinegg instability in a VTTR

    July 20, 2017
    In a vertical tubeside thermosiphon reboiler (VTTR), Ledinegg instability can occur when the tubeside pressure drop decreases with increasing flow rate. Theoretical analysis of two boundary conditions—constant heat flux and constant steam pressure—revealed that for either condition, Ledinegg instability can occur in a VTTR only when intube frictional pressure drop dominates...

  • Beware of Unauthorized Software

    July 10, 2017
    Software piracy is a significant problem for companies around the world. For some, the impact of piracy is simply a loss of revenue, but for highly technical software like HTRI Xchanger Suite®, pirated and cracked versions can lead to far more serious problems for our member companies, often in ways they...
