“…As AR decreases, the vortices number in the cavity increases. However, the strength of vortices reduces rapidly [13]. Only primary and secondary vortices in the deep cavity promote mass transfer.…”

Particles dispersion studies have attracted researchers' interest in understanding the physics behind the phenomena. Fluid-particle transport related to cavity flow is relevant to several natural and engineering applications such as cleaning of process equipment. This paper intends to provide a brief review of researches on the impact parameters, including geometrical parameters of the cavities, flow-related parameters, heat transfer and fluid-particles interaction and identifies opportunities for future research.

“…The changing shape and velocity of the primary vortex affecting the secondary, the formation of secondary vortex made the particles trap into the circulation of flow without enough drag to disperse out of the cavity. Furthermore, the primary vortex has a high value of kinetic energy, and the strength reduces rapidly for the secondary vortex as the cavity going deeper [32]. Therefore, in a deep cavity, the primary vortex is influential on the mass transfer of the fluid, thus, affecting the dispersion of particles out of the cavity.…”

Particles dispersion studies have attracted researchers' interest in understanding the physics behind the phenomena. Fluid-particle transport related to cavity flows is relevant to several natural and engineering applications such as cleaning of process equipment. However, there is no detailed discussion on the flow in the cavity channel with the dispersion of the particles and the combination of the effect of different geometric and fluid parameters with the presence of heat. This study is about predicting the behaviour of the solid particle dispersion in the channel with cavity and the interaction with the surrounding fluid with different geometrical, flow and particles parameters. Cubic Interpolation Pseudo-Particle (CIP) method was applied to solve the hyperbolic, advective term of vorticity transport Navier-Stokes equations coupled with energy equation in the two-dimensional, incompressible and laminar flow over the cavity and Eulerian-Lagrangian approach to model the dispersion of the particles inside the cavity. Flow inside cavity with an aspect ratio (AR) range from 0.5 to 4, and Reynolds number (Re) from 50 to 1000 were investigated. Validation studies were conducted numerically by evaluating the CIP method on the flow in the channel with the cavity. Qualitative comparisons between the numerical and experimental were evaluated and presented.

“…There are numerous studies about fluid flow over a cavity where researchers were showed the behavior of fluid streamlines inside a cavity [6]. In addition, studies of mass transfer in a cavity have appeared in the pertinent literature [7][8]. As a result, most previous studies have assumed that the fluid flow in a cavity already achieved steady state condition.…”

This paper provides numerical study of the effects of mixed convection on particles removal from a cavity using multi-relaxation time thermal lattice Boltzmann method (LBM) for compute the flow and isotherm characteristics in the bottom heated cavity located on a floor of horizontal channel. A point force scheme was applied for particles-fluid interactionand double-distribution function (DFF) was coupled with MRT thermal LBM to study the effects of various grashof number (Gr) and Aspect Ratio (AR) on the efficiency of particles removal. The results show that change in Grashof number and Aspect ratio causes a dramatic different in the flow pattern and particles removal efficiency.
