Wing airfoil geometric parameterization method for efficient aerodynamic design optimization

A new geometric parameterization method, called here as TBM (thickness-based method), was presented and evaluated through different optimization cases and algorithms. This method is based on the well-known CST and it keeps all the baseline characteristics of the core method: geometrical flexibility, surface smoothness and small number of design parameters.

Store Separation Analyses by means of Response Surface Modeling

In this study, a well-known store separation test case, EGLIN test case, is simulated by using CFD-based RSMs. For this purpose, the Grid Method which is used in wind tunnel tests and design of experiment methodology are applied. Design points are first determined for design of experiment and the results obtained at these points are used for generating RSMs in modeFRONTIER.

Design Optimization of a Supersonic Nozzle

This thesis was written with the aim of designing a high performance supersonic nozzle as an important aid to rocket propulsion and the space industry. The optimization goals are realized through calculations derived from optimization software modeFRONTIER and various computation fluid dynamics (CFD) multi-platform programs. 

Design of Modern Ferries with Optimized Performance in a variety of sea conditions

A multi-objective, single stage optimization process was implemented in order to improve the hydrodynamic performance of a fast displacement ferry. In this performance optimization of a ship, objectives were improving its calm and rough water sailing efficiency by minimizing its resistance and improving its seakeeping qualities. Model tests and CFD calculations are used. A custom parametric design of an existing conventional hull form was developed using CAESES.

CAE tools are improving at an ever increasing rate, yet the challenge lies in efficient management of CAE processes to ensure traceability.

Study to Develop Optimum Shape for Compressor Entrance Guide Vane

An inlet guide vane is designed for an Ecotorq EU6 engine in this study at Ford Otosan, Turkey. The optimization of this component is performed with a workflow built by modeFRONTIER software with focus on two main output parameters for the study, swirl ratio and pressure drop. The workflow incorporates CATIA, StarCCM+ and combines two operating systems (Windows and Linux).

Robust Design Optimization of a Free-Fall-Life-Boat (FFLB) Using Fluid-Structure Interaction and Kinematics Analysis

A free fall lifeboat, or FFLB, is the focus in this optimization methodology run in modeFRONTIER, coupling ANSA, Meta and the FSI solver. A Kinematic solver calculates the initial conditions of the FSI analysis for different initial positions of the vessel, provided by the DoE tool. The results lead to useful conclusions for the lifeboat's robust trajectory.
