This study exploresthe interaction between a propellerand various framearm geometries,which are typically used in multi-rotor applications. The influence of the arm on the propulsiveperformance of the propelleris investigated by using commercial computational fluid dynamics (CFD) solver ANSYS Fluent 17in hovering flight. CFD results are validated for hover and vertical climb conditions with thrust and torque measurements conducted on a 16x4 carbon fiber propeller. Four different arm geometries (i.e., an Eppler arm, a cylindrical tube, a square tube, and a slotted square tube) are studiedto investigate their effect on the propulsive performance of the propeller and the complete propeller-arm configuration. Regardless of the geometry, the arm enhances the thrust generation of the propellerfor all propeller-arm distances considered in this study. However, the total thrust of the propeller-arm configuration is smaller than the single propeller case due to drag exerting on the arm. In this respect, the Eppler armconfigurationhas the best performance in terms of the total forcegenerationdue to relatively low drag of the Eppler profile. Thesquare arm configuration yields the highest thrust generation and propulsive efficiency for the propeller despite having the lowest total force generation.

A Computational analysis on rotor-propeller arm interaction in hovering flight
Yener, Serkan.; Perçin, Mustafa; Department of Aerospace Engineering (2019)
This study presents a computational analysis on the interaction between rotor and different rotor frame-arm geometries in hovering flight. The influence of the frame arm on the aerodynamic performance of the rotor is assessed by using commercially available computational fluid dynamics (CFD) solver software ANSYS Inc. Fluent 17. Numerical results are validated for hovering and forward vertical climb flight conditions with thrust and torque measurements conducted on a 16x4 carbon fiber propeller. The thrust ...
Design and Optimization of Nanoantennas for Nano-Optical Applications
Işıklar, Göktuğ; Ergül, Özgür Salih; Department of Electrical and Electronics Engineering (2020-9)
In this study, design and simulation of plasmonic nanoantenna structures to obtain high power enhancement capabilities at optical frequencies, as well as utilization of nanoantennas for imaging and sensing applications are presented. Plasmonic characteristics of nanoantennas, which depend on many parameters, such as material, frequency, geometry, and size, are investigated in detail via computational analyses of various nanoantenna structures. Numerical solutions of electromagnetic problems are performe...
Atmosferik geçiş yapan araç etrafında navier- stokes denklemleri ile üç boyutlu hipersonik akış analizi
Özgün, Muharrem; Eyi, Sinan (2014-06-01)
Bu çalışmada hipersonik akışlar için kullanılabilecek isabetli ve etkin bir hesaplamalı akışkanlar dinamiği kodu geliştirilmesi amaçlanmaktadır. Akış analizi üç boyutlu Navier-Stokes denklemlerini temel almaktadır. Bu denklemler Newton metoduyla çözülmekte ve Jacobian matrislerini hesaplamak için analitik metot kullanılmaktadır. Model olarak alınan AS-202 Apollo uzay aracı geometrisi üzerinde akış parametreleri ve taşınımla ısı transferi analiz edilecektir. Ayrıca nümerik olarak stabil olan ve genelde hiper...
Numerical and experimental investigation of tubeaxial fan noise
Bodur, Ahmet; Çalışkan, Mehmet; Department of Mechanical Engineering (2014)
In this study, the noise characteristic of a tube axial fan is investigated numerically and experimentally. The effects of blockage plate in front of the tube axial fan on the tube axial fan noise level are experimentally investigated. A computational aero-acoustic method is used to predict the flow induced fan noise. This method couples a flow solver and a wave equation solver. Unsteady flow analysis is performed with URANS (Unsteady Reynolds Average Navier Stokes Equation) method while acoustics radiation...
CFD simulation of the developing boundary layer in an atmospheric wind tunnel
Kıran, Defne; Aksel, Mehmet Haluk; Çete, Ali Ruhşen; Department of Mechanical Engineering (2018)
Structural coupling methods are widely used in predicting dynamics of coupled systems. In this study, the reverse problem, i.e. predicting the dynamic behavior of a particular subsystem from the knowledge of the dynamics of the overall system and of all the other subsystems, is studied. This problem arises when a substructure cannot be measured separately, but only when coupled to neighboring substructures. The dynamic decoupling problem of coupled linear structures is well investigated in literature. Howev...
