Highlights
The convective flows resulting from uniform vertical buoyancy sources, which we term ‘distributed wall-source plumes’, occur widely within both geophysical environments and within the built environment
A high Richardson number is expected in the laminar region given that the buoyancy flux is being forced through the plate at very low momentum, i.e. there will be an excess buoyancy relative to the momentum
The flow resulting from a vertically distributed wall source of buoyancy was studied by forcing dense source solution through a porous wall
Summary
The convective flows resulting from uniform vertical buoyancy sources, which we term ‘distributed wall-source plumes’, occur widely within both geophysical environments and within the built environment. Any heated vertical surface within a building, be it from a radiator or from incident solar radiation. In these contexts the resulting distributed wall-source plumes are usually turbulent. We carry out simultaneous high-resolution experimental measurements of the velocity and buoyancy fields of turbulent distributed wall-source plumes in order to investigate the structure of the plume and the resulting entrainment of ambient fluid
