Educational: Shell-and-tube Heat Exchangers in Refineries
January 16, 2017
Oil refineries fractionate components by exploiting their boiling point differences. This process is energy intensive, requiring the oil to be heated to temperatures up to 750 °F. Heat exchangers are critical to recovering the heat input and to making the process more efficient and economical. Because of their key role in...

Research Update: Predicting Phase Separation in Shell-and-Tube Heat Exchangers
January 15, 2017
Recent experiments performed in the Multi-purpose Visualization Unit (MVU) analyzed the dependence of shellside phase separation on exchanger geometry. During this webinar, we discuss the variation of the stratified to non-stratified transition boundary with exchanger geometry, applicable over a wide range of flow regime parameters....

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....
