چکیده

In order to estimate Reynolds number effects on a transonic transport aircraft CFD calculations have been performed. The CFD calculations have been done solving the RANS equations on an unstructured grid for varying Reynolds number at transonic conditions. Low Reynolds number data have been extrapolated to a higher Reynolds number condition with different scaling methodologies in order to evaluate each methods strengths and weaknesses.

26th INTERNATIONAL CONGRESS OF THE AERONAUTICAL SCIENCES PREDICTION OF HELICOPTER MANEUVER LOADS USING A COUPLED CFD/CSD ANALYSIS

A fluid-structure analysis framework which couples Computational Fluid Dynamics (CFD) and Computational Structural Dynamics (CSD) is constructed to study the aero-mechanics of a helicopter rotor system under maneuvering flight conditions. The CFD approach consists of the solution of Unsteady Reynolds Average Navier Stokes (URANS) equations for the near-field of the rotor coupled with the dynami...

25th INTERNATIONAL CONGRESS OF THE AERONAUTICAL SCIENCES ADAPTIVE NODE DISTRIBUTION FOR ON-LINE TRAJECTORY PLANNING

Direct methods for trajectory optimization are traditionally based on a priori temporal discretization and collocation methods. In this work, the problem of node distribution is formulated as an optimization problem, which is to be included in the underlying non-linear mathematical programming problem (NLP). The benefits of utilizing the suggested method for on-line trajectory optimization are ...

Convective Heat Transfer from a Heated Rotating Disk at Arbitrary Inclination Angle in Laminar Flow

In this paper, experimental data and numerical results of heat transfer from a heated rotating disk in still air are presented over a large range of inclination angles and a dimensionless correlation is developed for forced, natural and mixed convection. The measured Nusselt number over the rotating disk is compared with the numerical results. The goal of the present research is to develop a se...

Development of a Low Cost and Safe PIV for Mean Flow Velocity and Reynolds Stress Measurements

In this study, a white light particle image velocimetry (WL PIV) system which employs a light sheet generated with a flash was used. The system was developed in order to provide a cost-efficient and safe alternative to laser systems while keeping the accuracy limits required for hydraulic model tests. To investigate the accuracy of WL PIV method under different flow conditions, experiments were...

Multilevel Monte-carlo Methods Applied to the Stochastic Analysis of Aerodynamic Problems

Abstract: This paper demonstrates the capabilities of the Multi-Level Monte Carlo Methods (MLMC) for the stochastic analysis of CFD aeronautical problems with uncertainties. These capabilities are compared with the classical Monte Carlo Methods in terms of accuracy and computational cost through a set of benchmark test cases. The real possibilities of solving CFD aeronautical analysis with unce...
