Computational Fluid Dynamic simulations of ship airwake are performed together with an actuator disk model for a rotor model hovering over the flight deck. The flow around Simple Frigate Shape 2 (SFS2) is computed in steady-state and unsteady conditions by solving RANS and hybrid RANS/LES equations. The unstructured grid is generated for the ship geometry. Also, an actuator disk is added into the model to investigate downwash effect of rotor on ship airwake and interaction of rotor and ship airwake.

Computational fluid dynamics simulations of ship airwake with a hovering helicopter rotor Orbay, Ezgi; Uzol, Oğuz; Sezer Uzol, Nilay; Department of Aerospace Engineering (2016) In this thesis, Computational Fluid Dynamic simulations of ship airwake for a simple ship geometry are performed for the horizontal and inclined deck configurations and also with and without the helicopter rotor over the deck. An actuator disk model is used for the CFD simulations of a rotor model hovering over the flight deck. All of the computations are performed by using a commercial finite volume CFD flow solver. The unstructured tetrahedral grids are generated in the computational domain including ship...
Computational fluid dynamics simulations of ship airwake Sezer Uzol, Nilay; Sharma, A.; Long, L.N. (2005-10-01) Computational fluid dynamics (CFD) simulations of ship airwakes are discussed in this article. CFD is used to simulate the airwakes of landing helicopter assault (LHA) and landing platform dock-17 (LPD-17) classes of ships. The focus is on capturing the massively separated flow from sharp edges of blunt bodies, while ignoring the viscous effects. A parallel, finite-volume flow solver is used with unstructured grids on full-scale ship models for the CFD calculations. Both steady-state and time-accurate resul...
Computational investigation of rotorcraft avionics bay cooling system Akın, Altuğ; Kahveci, Harika Senem; Department of Aerospace Engineering (2019) Computational investigation of a rotorcraft avionics bay cooling system is performed. Within the introduced system, the ambient air is supplied to the avionics-bay by a fan and exhausted back into the ambient after cooling the equipment inside. Depending on the fan and exhaust locations, hot zones may form around some of the equipment. The fan must provide a sufficiently high mass flow rate to keep the temperatures of the avionics equipment below the limits, while avoiding excessive amount of cooling to red...
Mathematical Modeling of the NOTAR Antitorque System for Flight Simulation Yavrucuk, İlkay; Uzol, Oğuz (2013-04-01) In this paper, a mathematical model of a helicopter NO TAil Rotor (NOTAR) antitorque system is developed for real-time flight simulations. The model consists of the circulation control tail boom, direct jet thruster, and the vertical stabilizers. The airflow inside the tail boom is modeled by dividing the flow into aerodynamic control volumes. The model features a bladeelement-type approach for modeling the mass flow through the axial fan blades as well as aerodynamic mass and momentum conservation calculat...
Numerical simulation of lateral jets in supersonic crossflow of missiles using computational fluid dynamics Dağlı, Efe Can; Aksel, M. Haluk.; Department of Mechanical Engineering (2019) In this thesis, numerical simulation method for modelling lateral jet in supersonic crossflow is presented. Lateral jet control provides high maneuverability to the missile at difficult flow conditions. Besides, jet in a crossflow case has a highly complicated flow domain which should be examined using numerical or experimental methods. In this study, numerical methods are used. The thesis consists of two main sections. In the first section, a validation study is conducted for numerical simulation method us...
