Wall suction is known to be an effective Laminar Flow Control (LFC) technique to delay laminar-turbulent transition, but its commercial implementation is still limited due to design and integration issues. In particular, current design tools that mod

Contrary to transition criteria, the parabolas method allow a sharp analysis of the transition phenomenon. This method relies on a database, created with a stability study of generic boundary layer profiles, and constitutes a robust and accurate meth

The projected increase in air traffic volume has led to a renewed interest in drag reduction research to reduce aviation’s environmental impact. One solution is wall suction, which can effectively postpone the laminar-turbulent transition of a boun

An experimental study of high level turbulence natural convection in a 4m-height differentially heated cavity was conducted at large Rayleigh numbers (4.0×1010≤ RaH ≤1.2×1011). In this study, turbulence quantities including θRMS (θ′), VRMS
