Validation of A Low Order Model for Closed Loop Flow Control Enabled Flight

Validation of a low-order model for closed-loop flow control enable flight Tchieu, Andrew A.; Kutay, Ali Türker; Muse, Jonathan A.; Calise, Anthony J.; Leonard, Anthony (2008-12-01) A simple low-order model is derived to determine the flow forces and moments on an airfoil that arbitrarily pitches and plunges with the presence of synthetic jet actuation for the use in an adaptive closed-loop control scheme. The low-order model captures the attached flow response of an airfoil in the presence of synthetic jet actuators near the trailing edge. The model includes two explicit non-linear states for fluid variables and can be easily coupled to the rigid body dynamics of the system. The model...

VALIDATION OF THE PARTICLE IN CELL MONTE CARLO COLLISION NUMERICAL CODE FOR THE RF DISCHARGE SIMULATION Kuşoğlu Sarıkaya, Cemre; Rafatov, İsmail; Çakır, Serhat (2016-3-01) We developed 1d3v Particle in Cell/Monte Carlo Collision (PIC/MCC) numerical code for the RF (radio-frequency) capacitive glow discharge. This method includes the solution of the Lorentz force equation for the motion of super particles and the Poisson equation for the electric field. Collisions between the particles are modeled with the Monte Carlo method. In this process, the isotropic and charge exchange collisions between the ion-neutral pairs, as well as the elastic, excitation and ionization collisions...
Validation of MISES Two-Dimensional Boundary Layer Code for High-Pressure Turbine Aerodynamic Design ANDREW, PHILIP; Kahveci, Harika Senem (ASME International, 2009-07-01) Avoiding aerodynamic separation and excessive shock losses in gas turbine turbomachinery components can reduce fuel usage and thus reduce operating cost. In order to achieve this, blading designs should be made robust to a wide range of operating conditions. Consequently, a design tool is needed-one that can be executed quickly for each of many operating conditions and on each of several design sections, which will accurately capture loss, turning, and loading. This paper presents the validation of a bounda...
Validation of Parallel WRF Downscaling Methodology using OpenFOAM Leblebici, Engin; Tuncer, İsmail Hakkı (2017-06-26) The main objective of this study is to obtain real-time atmospheric flow solutions using open source CFD solver OpenFOAM coupled with Numerical Weather Prediction (NWP) model; Weather Research Forecast (WRF). NWP can take moist convection, land surface parameterization, atmospheric boundary layer physics into account, but wind flow features finer than 1 km aren't captured by the turbulence physics of such models. CFD simulations, however, have proved to be useful at capturing the detail...
