Sommario/riassunto |
|
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 velocity ratings for shorter thermowells. The implications of this finding and possible remedies are discussed. |
