Comparison between Lagrangian and Eulerian approaches in predicting motion of micron-sized particles in laminar flows

Eulerian–Lagrangian modeling of solid particle behavior in a square cavity with several pairs of heaters and coolers inside

“…Such system a type of particulate flow, a multiphase system of disperse phase (solid particles) and the carrier phase (ambient fluid). several studies have been carried out to provide a better understanding of such multiphase system using the hybrid Eulerian-Lagrangian methods [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27], where the carrier phase and disperse phase are simulated by Eulerian and Lagrangian approaches (one-way or two-way coupled), respectively. A less typical approach, which is more suitable for denser particulate flows, is based on a continuum description of particle material (a multiphase non-Newtonian multiphase system) solved using an Eulerian-Eulerian or (more recently) LagrangianLagrangian approaches [28,29].…”

Eulerian–Lagrangian analysis of solid particle distribution in an internally heated and cooled air-filled cavity

“…Puragliesi et al [20] studied the effects of solid particle diameter on their flow patterns in a differentially heated cavity (DHC) to observe that by increasing the particle diameter to 10 lm the effect of gravitational forces becomes more important and therefore most of the depositions occurred on the bottom wall. Saidi et al [21] and Vegendla et al [22] studied the behavior of solid particles by using Eulerian-Lagrangian and Eulerian-Eulerian method for dilute gas-solid flow. They found that the Eulerian-Lagrangian method is more accurate than Eulerian-Eulerian method.…”

“…particle deposition on heat exchanger surfaces can reduce the heat transfer rate and adversely affect the energy efficiency of these equipment [8,9]. Therefore, several studies have been carried out to understand this problem using Eulerian-Lagrangian methods [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27].…”

Evaluating Dust Particle Transport Performance within Urban Street Canyons with Different Building Heights

“…When the flow domain is relatively complicated, this code can be used in conjunction with fluid flow solvers. Hence, at each fluid flow time step, this code interacts with flow properties computed by the solver, and the particle positions advance with time (Saidi et al, 2014). Because of the high particleto-air density ratio, dilute particle suspensions, negligible Brownian motion force, and thermophoretic forces, drag and gravity are considered the dominant forces away from the wall (Kleinstreuer et al, 2008).…”
