Breakup of Liquid Streams at High Pressures
Abstract
A theoretical and computational study of the break-up of injected liquid streams at high pressure by stress-induced cavitation is the research subject. The breakup criteria by stresses differs greatly from the traditional criterion in which a fluid cavitates at places and times at which the local pressure falls below the vapor pressure. Rather, cavitation occurs where the tensile stress exceeds the liquid breaking strength. The hydrodynamic stability and subsequent breakup of these liquid streams will be examined using viscous-potential-flow analysis and the direct numerical simulation of the viscous-fluid motions. The deformation of free surfaces and the fields of principal stresses are monitored to determine places and times at which the liquid is at risk to breakup.
