Abstract:
Turbulent convective plumes appears in natural complex systems such as the oceans
and the atmosphere. The theoretical description of these models is very important for
understanding the convective transports in these complex systems. The behavior of the
convective plumes is coupled with the environment in which they evolve. Although the
effect of the environment stratification has been the subject of numerous experimental,
analytical and numerical studies, the influence of the ambient co-flow received very little
attention. Until this day, we still do not have a theoretical description for the
three-dimensional round plumes in a uniform co-flow. In this work, the governing
equations for the round turbulent plumes are derived and analytical and numerical results
are presented. The obtained governing equations are the ordinary differential equations
that represents the conservation of mass, momentum, kinetic energy and buoyancy.
Finally, the comparison between the entrainment hypothesis and the energy-consistent
entrainment is discussed.
