This work studies the influence of crossflow transition modelling on the performance and
flow field of a controllable pitch propeller. The simulations are performed for two different …

A transition-predictive Reynolds-averaged Navier–Stokes (RANS) model is introduced as
the Reynolds controlling condition to constrained large-eddy simulation (TrCLES) to improve …

Algebraic transitional extensions for the accurate computation of laminar separation bubbles
are developed for use with k− ω models. The transitional model, based on integral boundary …

Predicting the laminar-turbulent transition is becoming a necessity in order to reduce margin
costs in the design of turbines and helicopter rotors. Most RANS models lack the capacity to …

Current trends in aero-engine design are oriented at designing high-lift low-pressure turbine
blades to reduce engine weight and dimensions. Therefore, the validation of numerical …

Hover is certainly the most important and critical flight condition of a rotorcraft. Hovering
capabilities ensure Vertical Take-Off and Landing and allow the rotorcraft to fulfill the most …

The flow within turbomachines is intrinsically complex and involves boundary layer
transition, separation and vortices such as the tip leakage vortex and wakes. In a low …

Flows in low-pressure turbines are highly dependent on the laminar-turbulent transition of
the boundary layer and the separation of the laminar boundary layer. This study focuses on …

The aerodynamic performance of axial turbines depends significantly on profile losses,
secondary flow losses, and clearance gap losses of vanes and blades. In modern high …

The use of transition models in Reynolds-averaged Navier–Stokes solvers is usually
accompanied by high values of the eddy viscosity at the inlet, due to the role of this quantity …
