Aero Optimization of Volvo S60 WTCC Race Car

The Volvo S60 is the racing car used by Cyan racing in the World Touring Car Championships. Optimization software modeFRONTIER was chosen for the aero optimization process of the vehicle, due to the complexity of the format of the championship, limited time and limited prior experience. 

Optimization of Active Grille Shutters Operation for Increased Fuel Economy

This presentations shows the optimization of active grill shutters in order to improve fuel economy and reduce drag penalty of a motor vehicle. The integration of softwares modeFRONTIER and Exa PowerFLOW facilitate the optimization process bringing valid results for the design of a more fuel-efficient vehicle.

Engineering success in the America's Cup

This presentation demonstrates new optimization solutions for Land Rover Bar yacht racing team and America's Cup races. The optimization examples use NX tools and software modeFRONTIER to find the optimal solution for improved efficiency in design.

3D shape synthesis of Vertical Axis Wind Turbine blades for specified wind distribution and tip speed ratio

The increasing demand for renewable energy resources have resulted in a preference for the vertical axis wind turbine, or VAWT. The aim of this paper is to develop a workflow that can develop an optimal blade shape in the VAWT. The methodology was based on the input wind speed distribution and TSR limits.

Optimization of a single-stage double-suction centrifugal pump using different Response Surface methods

The optimization of a double-suction centrifugal pump is explored in this study by the ACCUSIM project. Using optimizer modeFRONTIER and its MOGA II, focus was on optimizing the impeller geometry of the pump in order to increase efficiency. This study compares different response surface methods as an economical alternative to 3D CAE models.

Design of contracted and tip loaded propellers by using boundary element methods and optimization algorithms

This goal of this project is the optimization of a CLT propeller for increased efficiency. The design approach is based on a parametric description of the propeller blade and an in-house developed Panel Method/Boundary Element Method aimed to evaluate the performance of the propellers selected by a genetic optimization algorithm in the software modeFRONTIER.

Heat transfer enhancement and optimization of flat-tube multilouvered fin compact heat exchangers with delta-winglet vortex generators

This paper presents heat transfer enhancement of multilouvered fin compact heat exchangers with delta winglets vortex generators by using surrogate-based optimization. The optimization procedure is a combination of Artificial Neural Networks with Non-Dominated Sorting Genetic Algorithm (NSGA-II) in modeFRONTIER. Two Reynolds numbers and two different geometries were investigated..

Aerodynamic optimization of a sail-plan of a boat

This thesis presents the results of an optimization study of the geometry and layout of the sail-plan (genoa and mainsail) of a 12 meter prototype boat called Mefistofele. The goal is to maximize the ratio between boat speed and sail-plan surface, considering different upwind sailing conditions.

Three-dimensional numerical analysis of diesel combustion under cold ambient conditions

The purpose of this study was to clarify the relationship between the air–fuel mixture distribution and various multiple injection patterns based on both experiments and 3D computational fluid dynamics (CFD) simulations. Special attention was paid to the region near the glow plug under low-temperature conditions. The test engine was a four-cylinder direct injection diesel engine with a compression ratio of 15.0:1. The constants of the shell model were optimized using a genetic algorithm in modeFRONTIER.

Flutter Based Aeroelastic Optimization of an Aircraft Wing with Analytical Approach

This paper presents a flutter prediction methodology for three dimensional wing and wing/store configurations by using the well-known Goland and AGARD 445.6 aeroelastic wing models. Flutter analysis of the AGARD 445.6 wing is performed with an in-house flutter solution code coupled with the optimization software, modeFRONTIER.
