Transient combustion responses of homogeneous propellants to acoustic oscillations in axisymmetric rocket motors [PDF]
, 1997 A numerical analysis of unsteady motions in solid rocket motors has been conducted. The formulation considers a 2-D axisymmetric combustion chamber and a choke nozzle, and treats the complete conservation equations accounting for turbulence closure ...

Evaluation of the efficiency of cleaning dental plaque on titanium using a cavitating jet
Journal of Biomechanical Science and Engineering, 2014 Dental plaque, which adheres to the surfaces of dental implants and remains in the gingival crevices, can cause peri-implantitis, which is similar to periodontal disease; consequently, cleaning the dental plaque from these surfaces is very important.
