Getting Started: Building Your First Case in Xvib
June 06, 2019
If you’re new to Xvib, or simply need a refresher, this webinar will help you. The webinar provides an overview of how Xvib works so that you can use it to analyze the vibration potential—both fluidelastic instability and vortex shedding amplitude—of a specific tube in the bundle of a shell-and-tube heat...

STV-15 Select Crossflow Velocity Distributions for Analyzing Tube Vibration Potential
January 16, 2017
Both the value and distribution of velocity along each span are important for proper assessment of tube vibration potential. Because of the disparity in spatial resolution between the small-scale finite element structural model of Xvib® and the larger scale incrementation scheme of Xist®, engineering judgment is required to populate the important...

STV-16 Calculating Fluidelastic Instability of U-Tubes Near Inlet Nozzles
January 16, 2017
The challenges of a rules-based vibration screening in Xist® have often led to excessive conservatism for U-tubes positioned near the inlet nozzle. In this study, we simulated shellside diabatic flow over the U-bend portion of the bundle for a number of nozzle locations using computational fluid dynamics (CFD). Using the simulation...
