Inclined and horizontal wall plumes

Behavior of thermal plumes from two-heat sources in an enclosure

“…Low level of ambient stratification caused wall plumes to entrain fluid in the horizontal direction. Lin et al [12] studied both theoretically and experimentally the inclined wall plumes which arise from a line thermal source embedded at the leading edge of an adiabatic plate with arbitrary tilt angle. Sangras et al [13] described the measurements of the mixture fraction properties of plane buoyant turbulent adiabatic wall plumes, emphasizing conditions far from the source which self-preserving behavior is approximated.…”

Oscillatory Copper Deposition on Conical Iron Electrodes in a Nonuniform Magnetic Field

“…After a plume rises up, the boundary layer recovers, and the next plume starts to form, which is similar to the oscillation behavior discussed above. On inclined walls, depending on the density gradients on the surface, such intermittent buoyancy plumes may also appear [50]. On vertical walls, provided that the Reynolds number is low, a continuous, laminar boundary layer flow develops, which will not oscillate [49].…”

Inclined wall plumes in porous media

“…The solution to the nonsimilar equations ( 11)-( 13) of the inclined wall plume in a porous medium with boundary conditions ( 14) is obtained numerically using finite differences. At Lin et al (1996) noticed, it is very difficult to integrate the set of equations constrained by an integral equation ( 10), especially when this system of equations is nonsimilar. A considerable effort in this study has been directed toward developing a numerical method for the problem under consideration, which is different of that proposed by Lin et al (1996).…”

“…In this paper, we investigate the Darcian boundary-layer natural convection from inclined wall plumes which arise from a line thermal source imbedded at the leading edge of an adiabatic plate with arbitrary inclination from the vertical to the horizontal and immersed in a fluid-saturated porous medium. The problem is formulated based on the corresponding configuration for inclined wall plumes in a viscous (non-porous) fluid considered by Lin et al (1996). To facilitate the analysis, a dimensionless stretched streamwise coordinate ~ (or ~) has been proposed.…”
