DYNAFLOW, INC.
DYNAFLOW, INC.® founded in 1988 has established a reputation for quality R&D and testing work. The company pursues an inter-disciplinary approach to problem solving using a combination of scientific tools to achieve results. This is reflected in the diversity of research at DYNAFLOW, which includes contracts on hydrodynamics, cavitation, bubble dynamics, underwater explosion, liquid remediation, material testing, CFD research and software development from federal agencies, and consulting, development, and testing jobs from industry.
The DF_MULTI_SAP® product is an advanced multi-bubble dynamics code for Lagrangian tracking of a distribution of nuclei in a CFD computed or measured flow field. The code uses a spherical bubble dynamics model which incorporates knowledge of non-spherical effects acquired from studying bubble dynamics in complex vortical flow fields using DYNAFLOW's axisymmetric, 2DYNAFS©, code or three-dimensional, 3DYNAFS©, code. DF_MULTI_SAP® uses a Surface-Averaged Pressure (SAP) scheme to improve the classical bubble dynamics model in the Rayleigh-Plesset equation.
DF_MULTI_SAP(r) has been coupled to FLUENT as an add-on package, which is now available from Dynaflow and is suitable for studying bubble cavitation inception and bubbly flows involving bubble entrainment. DF_MULTI_SAP® benefits FLUENT users by providing convenient means of tracking bubble nuclei recording their trajectories, volume changes, dynamics, and acoustic signals generated by the bubbles. Industrial applications include bubbly flow, cavitation inception, and cavitation noise in turbo-machinery, marine propellers, bubble plumes, and pipe flows, etc.
