Whether it is a large container ship or a submarine operating at depths of hundreds of meters, propellers are in action to advance in the water. Counter-rotating propeller, abbreviated as CRP, is a combined propulsor where the propellers, called forward and aft, are placed one behind another and rotate in opposite directions. The main advantages of a CRP are increased efficiency due to less fuel consumption than a single propeller and torque cancellation phenomena by rotations in opposite directions. In the present study, design and performance analyses of a CRP are conducted for the bare hull geometry of DARPA Suboff. OpenProp which is an open-source computational tool for the design and analysis of propellers written in the MATLAB programming language is used as the parametric analysis and design tool. ANSYS Fluent is used for performance evaluations. The methodology for design and numerical analyses is set with a propeller called DTMB4119 and validated with an experimental data.

Numerical investigation of the behaviour and performance of ships advancing through restricted shallow waters Terziev, Momchil; Tezdogan, Tahsin; Oğuz, Elif; Gourlay, Tim; Demirel, Yigit Kemal; Incecik, Atilla (2018-01-01) Upon entering shallow waters, ships experience a number of changes due to the hydrodynamic interaction between the hull and the seabed. Some of these changes are expressed in a pronounced increase in sinkage, trim and resistance. In this paper, a numerical study is performed on the Duisburg Test Case (DTC) container ship using Computational Fluid Dynamics (CFD), the Slender-Body theory and various empirical methods. A parametric comparison of the behaviour and performance estimation techniques in shallow wa...

PERFORMANCE COMPARISON OF SU2 REAL GAS MODELS AND TESTING FOR A COLD GAS THRUSTER Özden, Aysu; Baran, Özgür Uğraş; Aksel, Mehmet Hâluk (null; 2019-09-19) Cold gas propulsion systems are mainly used for attitude controlof satellites.It is possible to obtainvery low pressure and temperature at the exit section of the nozzledue to propulsion system’s nature. Investigation of steady state performance of a cold gas thruster under real gas effects is decided to be carried out. SU2, an open source compressible CFD tool,is used for analyses ofideal gas, Peng-Robinson and van-der Waals gas models. Vacuum chamber test facility of Roketsan is usedfor performance tests....
Simulation of the Transient Response of a Helicopter Turboshaft Engine to Hot-Gas Ingestion Uzol, Oğuz; Yavrucuk, İlkay (2008-06-09) Hot-Gas Ingestion (HGI) to the engines can potentially occur when a rotorcraft or a VTOL/STOVL fixed-wing aircraft is operating in close proximity to the ground. Especially for helicopters, due to the rotor downwash hot exhaust gases get recirculated into the engine inlet. Similar conditions may also occur due to the ingestion of hot exhaust gases from rocket launchers or gun fire. In this study, we present the results of a simulation of the transient response of a helicopter turboshaft engine to HGI. Speci...
Mathematical model development of the anti torque system of a notar helicopter Bakır, Hüseyin Murat; Yavrucuk, İlkay; Department of Aerospace Engineering (2008) The anti-torque mechanism of a NOTAR helicopter is a complex system including vertical tail and pressurized tail boom which provides air ejection used for both circulation control around the boom and creating directed jet air at the end of the boom. This thesis targets the modeling of this mechanism and integrating it to a helicopter simulation model. Flight tests are performed on the MD 600N helicopter to verify the results. Finally, the simulation is compared with flight test data.
