THERMOWELL VALIDATION TESTS - VortexWell
NEL Ltd was commissioned to carry out a series of laboratory tests and analyses to evaluate the resilience of two types of thermowell, namely standard thermowell and Okazaki VortexWell, to be operated in the oil flow facilities. In parallel with the laboratory tests, both finite element (FE) and closed form techniques were employed to verify test results. Having obtained the test and analytical data, a comparative study was also instituted to evaluate the dynamic performance and mechanical strength of the designated thermowells. Further work is recommended to undertake a computational fluid dynamic simulation (CFD) to investigate if unsteady flows and installation effects could affect the dynamic performance and hence induce higher loading magnitude over the two thermowells. Also, further laboratory tests could be carried out to individually and independently test the VortexWell and standard thermowell on NEL’s flow process line and an experimental modal analysis could be carried out to verify if natural frequencies of these two thermowells could be influenced by installation effects and unsteady flows.
