As the free stream velocity continues to increase, the flow characteristics change to turbulent forced convection flow. The introduction of small free stream velocity on turbulent natural convection flow suppresses the turbulence and decreases the heat transfer from the wall. However, as the salt concentration mixes with the fluid, the denser salt water is pulled down by gravity, inciting. At the beginning of the simulation, the water inside the porous medium is pristine and stationary. As a further simplification, assume the surrounding fluid is quiescent (u 0) and that the particle is initially at rest (q 0 and v 0 at time t 0).Suppose we align our coordinate system so that the gravity vector points in the y. Snapshots of the salt concentrations in the sandstone using the COMSOL Multiphysics solution to the buoyancy-flow benchmark problem.
The results confirmed the use of a combined Grashof number (GR. p has units of time and is usually called the Lagrangian time scale or the particle velocity response time, for reasons that will soon be apparent. However, the deviation in the flow pattern of system 1 surprised us. The abnormal distribution of free charge (Figure 6(c)) causes a deviation in the flow pattern of system 3. The convective flow patterns occurring have been observed using Schlieren photography. The flow direction obtained by Behjatian and Esmaeeli 13 is marked using red rotating arrow in systems 1 and 3 (Figure 7(a) and ). This paper reports on simultaneous heat and mass transfer in free convection at horizontal cylinder electrodes that has been investigated experimentally using the electrochemical limiting diffusion current technique.
