  1. Noise prediction and control for the failure of a quartz window in a high pressure test cell.

    Article - En anglais

    This paper reviews the theory of jet noise prediction, presents results of noise prediction and measurements, and discusses the test results in terms of compliance with regulatory requirements.

    A high-temperature /high-pressure (HTHP) visual test cell is used to test drilling muds.

    The cell has two l inch diameter quarts glass viewing ports and is shielded by an open top composite cylindrical wall.

    Shock noise levels at the operator's position (3 ft from the barrier) were predicted with a mathematical model based on jet noise theory for the quarts glass rupturing.

    The predicted results indicated that noise levels at this position may be near the Occupational Safety and Health Administration's (OSHA) limit of 140 dB for impact or impulse noise.

    Simulated tests closely confirmed predicted results.
