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

作者：

Highlights：

• The Eulerian–Lagrangian method was used to study free convection in a cavity.

• Particle deposition and distribution for this problem is investigated.

• Effects of different forces are investigated using a sensitivity analysis approach.

• Thermophoretic force can significantly affect the distribution of particles with dp = 1 μm.

• It is also found that at low Rayleigh numbers the particle distribution is strongly non-uniform.
