Always verify that the software implements the 2016 (R2022) version, as earlier versions may lack the Scruton number criteria. The most common limit
The shedding frequency is calculated as: $$f_s = \fracS \cdot Vd$$ Where: Always verify that the software implements the 2016
If any answer is “no” or “unsure,” do not proceed – consult a senior engineer or perform a detailed FEA.
Before signing off on any thermowell installation, verify the following against :
When fluid flows past a thermowell, it creates a phenomenon known as . This creates wake frequencies that can cause the thermowell to vibrate. If these vibrations match the thermowell’s natural frequency, resonance occurs. Unchecked resonance leads to metal fatigue and can snap a thermowell in seconds, potentially causing high-pressure leaks or environmental disasters. Scope and Applications
