Numerical modelling focused on the continued development of a prescribed wake vortex model for HAWT [horizontal axis wind turbine] performance prediction. This model represents the turbine blades as lifting lines from which emanate filaments of trailed vorticity. In yawed flow, additional filaments of shed vorticity are produced and the unsteady loading on the blades is represented by a semi-empirical unsteady aerofoil model. 1, record 2, English, - prescribed%20wake

Usually, Marangoni convection is obscured by density-driven convective flows. Limited experience during space experiments indicates that above a critical Marangoni number(ratio of surface tension force to viscous force), the flow becomes unsteady and temperature fluctuations in the melt are observed. In addition, a detailesd series of ground and low-gravity experiments have demonstrated that striations due to Marangoni convection are produced in float-zone grown silicon. 2, record 4, English, - Marangoni%20number

The computer method consists of applying the three full Navier-Stokes equations of fluid mechanics(...) over a pattern of points on a theoretical airframe before any hardware exists. Plotted over a sufficiently large number of points around an aerodynamic shape, these equations can predict lift, drag and heating. Some unsteady [air] flow patterns, such as the 3, 000 Hz shock wave buzz round the inlet spike of a missile at Mach 3, have been successfully plotted. 1, record 7, English, - inlet%20spike

La méthode sur ordinateur consiste à appliquer les trois équations complètes de Navier-Stokes sur la mécanique des fluides (...) à un certain nombre de points d'une cellule théorique. Si on les applique à un nombre suffisant de points d'une surface aérodynamique, elles permettent de connaître la portance, la traînée et l'échauffement cinétique. Cette méthode a permis de déterminer correctement certains types d'écoulements instables, tels que le "bourdonnement" de 3000 Hz dû aux ondes de choc, qui se produit à Mach 3 autour du cône d'entrée d'air d'un missile. 1, record 7, French, - c%C3%B4ne%20d%27entr%C3%A9e%20d%27air
