Critical frequency estimates for thermowells covered under ASME PTC 19.3 /
The ASME Performance Test Code, PTC 19.3, establishes the velocity ratings of thermowells in terms of a simplified resonant frequency estimate. The theoretical basis for this is examined and compared with discrete element methods. It is found that the code calculation fails to guarantee conservative...
