ABSTRAKT

Isobaric and isometric test procedures are typically used in lieu of more conventional hydrostatic tests on buried airport fuel hydrant systems; using currently installed equipment, the isometric test is implemented in a spreadsheet-style application, designed for ease-of-use by operating and maintenance personnel on-site who may not have a knowledge of fluid flow, heat transfer, and thermodynamics. Visual Basic for ApplicationTM (VBA) program execution is initiated through buttons provided on data worksheets. Final analysis results in a recommendation that the test may be considered satisfactory (i.e., the likelihood of a leak is small), or that a leak (or leaks) exist(s) with an estimate of the magnitude of the leak. Model design was conducted using the REFPROP program from the National Institute of Standards; REFPROP calculations were validated using a simple one-dimensional COMSOL heat transfer simulation. On-site testing and validation of the leak testing program will be performed during summer 2012.
