CFD Study of a New Annular Lift Fan Configuration with High Lift Efficiency
A new annular lift fan configuration that has very high lift efficiency is explored by using a numerical scheme. The inlet lip radius and diffuser angle are maximized by semicircle duct walls and the location of the lift fan is moved from the throat to the diffuser area to maximize the diffusion effect of the ducted fan. The improved lift fan achieves the figure of merit of 0.772 and the power ...
متن کاملCFD study on NACA 4415 airfoil implementing spherical and sinusoidal Tubercle Leading Edge
The Humpback whale tubercles have been studied for more than a decade. Tubercle Leading Edge (TLE) effectively reduces the separation bubble size and helps in delaying stall. They are very effective in case of low Reynolds number flows. The current Computational Fluid Dynamics (CFD) study is on NACA 4415 airfoil, at a Reynolds number 120,000. Two TLE shapes are tested on NACA 4415 airfoil. The ...

متن کاملConvergence Based Prediction Surrogates for High-lift CFD Optimization
Using a surrogate model to evaluate the expensive fitness of candidate solutions in an evolutionary algorithm can significantly reduce the overall computational cost of optimization tasks. In this paper we analyze the convergence profiles of a multi-element high-lift system, revealing insights into the flow physics of the system and how CL varies for different numbers of flow iterations. A hybr...
متن کاملFlying-Hot-Wire Study of Flow Past an NACA 4412 Airfoil at Maximum Lift
Hot-wire measurements have been made in the boundary layer, the separated region, and the near wake for flow past an NACA 4412 airfoil at mad mum lift. The Reynolds number based on chord was about 1,500,000. Special care was taken to achieve a two-dimensional mean flow. The main instrumentation was a flying hot wire; that is, a hot-wire probe mounted on the end of a rotating arm. The probe velo...
