Local nonsimilarity method for the two-phase boundary layer in mixed convection laminar film condensation [PDF]

open access: yes, 2018
The two-phase boundary layer in laminar film condensation was solved by Koh for the free convection regime and forced convection regime using the similarity method. But the problem on mixed convection does not admit similarity solutions. The current work

Impact of Fiber Orientation in Electrospun PLA Scaffolds on Fluid Dynamics in a Custom Microfluidic Device

open access: yesAdvanced Healthcare Materials, EarlyView.
Fiber orientation in electrospun scaffolds affects permeability and fluid dynamics in microfluidic devices. Combining experimental data with computational fluid dynamic simulations, we show that aligned fibers enhance flow uniformity, reduce pressure and shear stress variability.

Cooling photovoltaic panels with air convection – Parametric environmental and economic analysis with case studies

open access: yese-Prime: Advances in Electrical Engineering, Electronics and Energy
Photovoltaic (PV) panels generate electricity due to photoelectric effect, harvesting solar radiation from the sun. However, the hit of photons on the upper surface of the PV panel increases its temperature, and as a result, decreases its efficiency. The

Hierarchically MOF‐Based Porous Monolith Composites for Atmospheric Water Harvesting

open access: yesAdvanced Materials, EarlyView.
This review explores the design of hierarchical porous materials for atmospheric water harvesting, focusing on metal‐organic frameworks (MOFs) and porous monoliths. Emphasis is placed on integrating MOF nanoscale porosity with the microscale channels of monolithic scaffolds to enhance sorption‐desorption performance.
