International Journal of Heat and Mass Transfer
The enhancement of natural convection flow and the associated heat transfer in a differentially heated cavity with two horizontal adiabatic fins attached to each sidewall are numerically investigated at different Rayleigh numbers and with various fin positions in this study. The numerical approach is validated by both representative scales and experimental shadowgraph results. A typical double-plume flow regime is identified at both the early and fully-developed stages. The interaction of the two plumes is investigated in detail in this paper. With the increasing of the Rayleigh number, the separation frequency of the plume above both fins increases. It is also revealed that the separation frequency of the upstream plume at the quasi-steady stage does not only depend on the characteristics of the upstream flow, but also greatly depends on the position of the downstream fin. The frequency varies non-monotonically as the downstream fin moving toward the cavity ceiling, suggesting complex nonlinear characteristics. Compared to the scenario without any fin, the flow rate across the cavity is significantly boosted, which is increased by up to 136.2% at the early stage and 124.8% at the fully-developed stage. The heat transfer rate across the cavity having symmetrical fins on sidewalls is enhanced by up to 12.7% at a Rayleigh number of 3.68 × 109.

Controlled 3D nanoparticle deposition by drying of colloidal suspension in designed thin micro-porous architectures

Nanoparticle deposition by drying of colloidal suspension in thin micro-porous architectures has attracted a lot of attention in scientific research as well as industrial applications. However, the underlying mechanisms of such three-dimensional (3D) deposition are not yet fully revealed due to the complexity of the co-occurring processes of two-phase fluid flows, phase change and mass transport. Consequently, the control of 3D nanoparticle deposition remains a challenge. We use a combined experimental and numerical approach to achieve controlled 3D nanoparticle deposition by drying of colloidal suspension in two pillar-based thin micro-porous architectures. By the design of pillar layout, rectangular-spiral and circular-spiral deposition configurations are obtained globally. By varying the surface wettability, vertically symmetric and sloped nanoparticle depositions can be achieved locally. While the numerical modeling reveals the mechanisms of liquid internal flow, as well as the impact of local drying rate on nanoparticle transport, accumulation and final deposition, the experimental results of deposition configurations validate the controlling strategies. This combined experimental and numerical work provides a framework to achieve desired 3D nanoparticle deposition in thin micro-porous architectures, with a thorough understanding of the underlying mechanisms of two-phase fluid flows, phase change and mass transport.
