Noise, vibration, and … harshness?

December 04, 2023

NVH (noise, vibration, and harshness) is an increasingly important design metric for many commercial products—from vacuum cleaners and dishwashers, to lawnmowers and chain saws, to cars, trucks, and aircraft. Consumers demand a product that performs well but with low "observables." The first two qualities are measureable. A sound power meter can...

TT-31 Beware of flow obstructions in inlet and outlet regions

February 14, 2023

Component: Xist, Xvib Applicable to: All supported versions (Version 8.2 and Version 9.x) Date posted: 14 February 2023  Flow obstructions in the inlet and outlet regions can invalidate the Xist bundle entrance and exit velocities and thus impact the rho-V2 calculations. The Xist vibration analysis for shell and bundle entrance and exit...

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...

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...
