The gas-kinetic BGK scheme on unstructured hybrid grids is presented. In order to accurately resolve the boundary layers in wall bounded viscous flow solutions, quadrilateral grid cells are employed in the boundary layer regions normal to solid surfaces while the rest of the domain is discretized by triangular cells. The computation time, which is a significant deficiency of the gas-kinetic schemes, is improved by performing computations in parallel. The parallel algorithm for hybrid grids is based on the domain decomposition using METIS, a graph partitioning software. Several numerical test cases are presented to show the accuracy and robustness of the proposed approach.

Parallel Computation of 3-D Viscous Flows on Hybrid Grids
Ilgaz, Murat; Tuncer, İsmail Hakkı (2009-10-12)
In this study, a newly developed parallel finite-volume solver for 3-D viscous flows on hybrid grids is presented. The boundary layers in wall bounded viscous flows are discretized with hexahedral cells for improved accuracy and efficiency, while the rest of the domain is discretized by tetrahedral and pyramidal cells. The computations are performed in parallel in a computer cluster. The parallel solution algorithm with hybrid grids is based on domain decomposition which is obtained using the graph partitio...
Design Methodologies of a Distributed Propulsion Aircraft
Fouda, Mahmoud; Haq, Rameezul; Naeem, H Nabih; Saeed, Muhammad Asif; Wanyonyi, S Nafuna; Cigal, Nazlıcan; Beker, Can; Yayla, Metehan; Kurtuluş, Dilek Funda (null; 2019-09-20)
This paper discusses the conceptual design of a hybrid thin haul air taxi. It presents a design methodology for a distributed propulsive hybrid aircraft highlighting the differences in design procedures between conventional design and hybrid distributed propulsion design. In addition, it demonstrates the impact of both hybridization and distributed propulsion on the reduction of direct operating cost for operators. The aim of the design is to offer a better alternative aircraft to serve the emerging new mar...
Multi-physics design optimisation of a GaN-based integrated modular motor drive system
UĞUR, MESUT; Keysan, Ozan (2019-06-01)
Here, a multi-physics approach is presented for the design optimisation of an integrated modular motor drive (IMMD). The system is composed of a modular permanent magnet synchronous motor (PMSM) and a GaN-based modular motor drive power stage. The multi-physics model includes motor drive inverters and DC-link capacitor bank (electrical model), stator windings and rotor magnets (electromagnetic model), heat sink (thermal model), and a geometrical model. The main purpose of the design optimisation is to obtai...
Cooperation control of three UAV’s for Aerial Rescue and Aerial Retrieval
Erkmen, Aydan Müşerref; Yavrucuk, İlkay (IEEE; 2009-12-14)
In this paper two new conceptual robotic system designs, called 'aerial-retrieval' and 'aerial-rescue' are presented and demonstrated by simulation results. The Unmanned air vehicles (UAV) used in this design are thrust vector controlled robotic systems. The 'aerial-retrieval' concept aims at entrapping and retrieving a (lost) floating object in the air. The second concept, 'aerial-rescue' aims at rescuing a free falling object (e.g. a person) in the air using a stretched net attached to the UAV's. Position...
Multiobjective design optimization of rockets and missiles
Öztürk, Mustafa Yavuz; Tekinalp, Ozan; Department of Aerospace Engineering (2009)
Multidisciplinary design optimization of aerospace vehicles has attracted interest of many researchers. Well known aerospace companies are developing tools for the mutlidisciplinary design optimization. However, the multiobjective optimization of the design is a new and important area investigated very little by the researchers. This thesis will examine the approaches to the multiobjective and mutlidisciplinary design optimization of rockets and missiles. In the study, multiobjective optimization method cal...
