Aircraft Wake Vortex Transport Model
Journal of Aircraft, 1973An analysis has been developed for high-aspect-ratio jet-flap wings of arbitrary geometry and blowing. It appears that the present method is as accurate as other known methods and is flexible and rapid, particularly for discontinuous planforms. Although definitive test data are lacking, correlation with existing experimental data is satisfactory.

Propeller Wake Alignment Models
SNAME 8th Propeller and Shafting Symposium, 1997Various wake alignment techniques which have been developed in the past for the analysis of non-cavitating propellers in uniform inflows are reviewed and some of them are extended in the case of cavitating flows subject to inclined inflows. The effect of the inclined trailing wake geometry on the predicted cavities and blade forces is found to be ...

Wake Interaction Effects Using a Parallelized Free Vortex Wake Model
34th Wind Energy Symposium, 2016Turbine-wake interactions pose significant challenges in the development of optimal wind farm configurations. These interactions can lead to a marked reduction in wind farm power efficiency as well as an increase in structural loading, which reduces the functional lifetime.

Different models of wake expansion are presented in this chapter: the 1D momentum theory model, the cylinder analog model and Theodorsen’s model. Far wake models such as the ones from Frandsen or Rathmann or only briefly mentioned. The different models are compared to each other. Results from this chapter are used in Chap.

Stochastic model for turbulent, reacting wakes
Aerothermochemistry of Turbulent Flows Conference, 1965Electron density fluctuations in a turbulent wake are examined by means of a stochastic model. The gas velocity fluctuations are prescribed, both in mean values and in statistical properties, and the chemical rate and continuity equations are solved for an ensemble of velocity samples.

Aerodynamic Investigation of Hover Using Vortex Ring Wake Model and Free Vortex Wake Model
AIAA SCITECH 2025 ForumModeling rotor inflow and wake dynamics is fundamental to understanding and improving rotorcraft performance. Especially, hover modeling plays an important role in aircraft design, aerodynamic assessments, and the development of control systems for helicopters and eVTOLs.

A model of shiftworker sleep/wake behaviour
Accident Analysis & Prevention, 2012Software-based biomathematical models of alertness provide a means to estimate fatigue-related risk in advance of a schedule being worked. Obtaining a good estimate of employees' sleep/wake behaviour during non-work periods is critical in obtaining accurate estimates of alertness.
