Water Spray Interaction with Dense Gas Clouds

May 7, 2012
Submission by: Robert N. Meroney, PhD. Wind Engineering Software, and Civil and Environmental Engineering, Colorado State University, Fort Collins, CO., USA Water spray curtains can provide an effective and rapid dilution mechanism for low lying dense clouds.  Frequently such clouds are released as a result of a chemical manufacturing, storage or gas transportation accident. Extensive field and laboratory tests have been performed to determine how well water curtains can mitigate actual spill conditions.  Numerical methods are often proposed to provide system design or timely response information, but most of these models reduce mathematical and computational complexity by integrating the equations of motion over volumes, sections or depths which provides computational speed but often sacrifices mixing detail and typically presume the use of empirical entrainment relationships.  Read More...
