Abstract:

Numerical simulations of buoyant plumes driven by different buoyancy flux sources: oil, gas bubbles or a hybrid case.

Purpose:

Use turbulence resolving simulations to analyze the effect of the inlet buoyancy flux nature (thermal or gas phase) on the plume turbulence characterization.

Data Parameters and Units:

Non-dimensional data: buoyancy flux, volume flux, momentum flux, buoyancy frequency (1/s), thermal expansion coefficient (1/K), gravity acceleration (m/s^2), turbulent kinetic energy, vertical location (z)
