RBSA or GVLV
We have two modules to calculate the likelihood for vibrations in a shell-and tube heat exchanger. One is called RBSAand the other GVLV.
RBSAis based on TEMA. It is quite conservative. When the calculations results in no warning for vibration, than you are pretty safe.
Sometimes you might want a more realistic calculation, because you want to go to the edge. Our GVLV module is the right way to do this.
It is based on research by Prof. Gelbe from the Technical University in Berlin.
For safety reasons, we still recommend aiming for a vibration hazard level of no more than 85%, as there is still some uncertainty.
