Direct numerical simulation of jets in fluids with stable density stratification
Samuel Schofield, University of Arizona
The finite Reynolds number behavior of a negatively buoyant jet injected into a fluid with stable density stratification is examined. Three-dimensional and Hele-Shaw experiments have shown instabilities in the jet leading to varicose and sinusoidal modes. Direct numerical simulation of the Boussinesq equations using high order spectral element methods can capture the instability modes and provide detailed information on the flow.
