Application of Hofer’s formula in thermal hydraulic calculations of oil transportation systems
Prospecting and Development of Oil and Gas FieldsHydrodynamic calculations are a mandatory procedure when designing new and upgrading and operating existing oil transportation systems, which are performed using computer methods. The implementation of new calculation technologies creates conditions for the use of more accurate mathematical models to describe the hydrodynamic processes that accompany ...

Advanced Materials, EarlyView.An Aloe‐pinspired droplet electricity generator (A‐DEG) overcomes the limited energy collection zone of conventional DEGs by guiding impact droplets through a channeling midrib and artificial cuticle. The channeling midrib induces uni‐directional droplet spreading, while the artificial cuticle on the midrib further reinforces this behavior through its ...

Humid‐Air Condensation Heat Transfer on Hierarchical Structured Superhydrophobic Graphite Composites
Advanced Materials Interfaces, EarlyView.Humid‐air condensation on graphite composites shows that making a surface superhydrophobic is not sufficient to enhance heat transfer. A hierarchical CuO/lauric‐acid coating yields spherical droplets but promotes Wenzel‐type pinning and adds effective thermal resistance under operation.
