Bubble Departure Diameter Prediction Uncertainty

Prediction of bubble departure in forced convection boiling: A mechanistic

Flow Boiling on Micropin Fins Entrenched Inside a Microchannel—Flow Patterns and Bubble Departure Diameter and Bubble Frequency

Flow boiling of HFE 7000 in five parallel microchannels of 222 m hydraulic diameter, each containing a single row of 24 in-line 100 m pin fins, was investigated. High speed photography revealed the dominant flow patterns, namely, the bubbly flow, the multiple flow, and the wavy-annular flow. The interaction of the bubble with the pin fins during nucleate boiling from G 350 kg /m2 s to G 827 kg ...

Airline Departure Delay Prediction

As any frequent flier is no doubt aware, flight delays and cancellations are a largely inevitable part of commercial air travel. In the past ten years, only twice have more than 80% of commercial flights arrived on-time or ahead of schedule. Punctuality is an issue for all major carriers, with some struggling more than others: through September 2008, American Airlines flights were on time just ...

Uncertainty analysis for shock-bubble interaction

In this paper, we have investigated the effect of uncertainties on the interactions of a bubble with a shock, based on a widely studied experiment case of helium-air shockbubble interaction. Gas contamination inside the bubble and deformation of the initial bubble shape were selected as the uncertainty parameters, and the statistics of the interface evolution and the primary baroclinic vorticit...

Optimizing Integrated Arrival, Departure and Surface Operations Under Uncertainty

In airports and surrounding terminal airspaces, the integration of arrival, departure and surface scheduling and routing have the potential to improve operations efficiency. Recent research developed a mixed-integer-linear-programming algorithm-based scheduler for integrated arrival and departure operations in the presence of uncertainty. This paper extends previous research to the surface to i...
