in this work, harmony search meta-heuristic optimization algorithm has been developed for aerodynamic shape optimization problem for the first time. the aerodynamic shape, which has been investigated, is an airfoil with parces method for its shape parameterization. the problem was minimization of aerodynamic objective function using inverse design method and the objective function has been the ...

Obtaining droplet collection efficiency (DCE) is vital for icing numerical simulations. A impact model based on the Eulerian two-phase flow was established in this work to analyze influence of different incoming parameters DCE. Then, mathematical regularity DCE distribution explored using parametric description, and functional relation between condition accomplished. The results showed that cal...

In this paper we present a unigrid multi–model formulation for transonic flow calculations based on solving, in sequence, the full potential equation and the the Euler equations. The goal is to minimize the overall computation time to simulate steady flows by using a more computational efficient physical model in the early iteration steps. The proposed method is based on two steps. In the first...

Large eddy simulations are performed to study tonal noise generation by a NACA0012 airfoil for Reynolds numbers in the range $0.5\ifmmode\times\else\texttimes\fi{}{10}^{5}\ensuremath{\le}R\phantom{\rule{0}{0ex}}e\ensuremath{\le}4\ifmmode\times\else\texttimes\fi{}{10}^{5}$. Different flow patterns responsible originate from laminar separation bubbles over surface. Intermittency and transition tu...
