A Study on Reduction of Heat Loss by Optimizing Combustion Chamber Shape

A method to improve fuel consumption in diesel engines is to enhance their theoretical thermal efficiency by increasing their compression ratio. In this case, reducing heat loss to the chamber wall is important to effectively benefit from a high compression ratio. To meet this challenge the combustion chamber shape was optimized using CONVERGE and modeFRONTIER. 

A New Automated Underhood Thermal Management CFD DoE Workflow with ModeFRONTIER

Ford engineers are challenged to find a cost efficient cooling system concept for the underhood thermal management that suits different powertrains and environments, respecting standards (NACA duct) and without compromising the vehicle’s aerodynamic performance. From a thermodynamics perspective, the problem to address regards the high temperatures deriving from the friction inside the PTU (Power Take-off Unit) and surrounding parts which can cause the oil to overheat.

ECS System Simulation - Architecture and Performance Optimization from the Early Phases of the System Design

This case study from Alenia Aermacchi’s Environmental Control System (ECS) department shows how the different design disciplines involved are handled effectively through process integration and automation, enabling the optimization of the overall performance from the early stages of system design.

CFD-Based Optimization Methods Applied to Polymer Die Design

Researchers explored the potential of CFD associated to RSM and optimization techniques in the design processes of the chemical industry. Two polymer die design examples were explored using different slot die geometries, different CFD codes, and different optimization packages and methods.

Front Shape and Slipstream for Wide Body Trains at Higher Speeds

Study the slipstream air speeds of wide body Bombardier trains at high speeds so that designers can meet the various requirements for front end shapes and develop a prediction methodology. An efficient optimization methodology implemented in modeFRONTIER helped optimize the performance and take all constraints into account early in the design cycle saving time and cost.

Design by Optimization of a Controllable Pitch Marine Propeller

Cavitation, or boiling, is a result of low pressure and flow speed rather than high temperature in water. The higher the speed of a propeller, the lower the pressure in water and therefore the higher levels of cavitation. Researches wish to design a propeller that delivers the same thrust (both at the design and at the reduced pitch working points) in order to reduce the cavitation phenomena and, consequently, the resultant radiated noise. 

modeFRONTIER helps Cummins Improve Engine Performance

Cummins Engine, a leader in the manufacturing of diesel and natural gas-powered engines for a wide range of transportation and equipment purposes, has created a new power module ready to take on the stringent US - EPA regulations. It is significantly more compact and cost-effective than medium-speed engines at the same horsepower. It took 150 engineers to design it, and modeFRONTIER helped the High Horsepower group find the optimal valve timing, hence reducing fuel consumption.

Driving Product Development with CAE and System Design at Whirlpool Corporation | UM14

Whirpool aims to cultivate advanced engineering knowledge in dynamics, structures, fluids, thermodynamics and controls, and embed it in the design process. In doing so, they strive to shorten the design cycle, minimize the reliance on build-and-test methods and leverage the global talent within the company.

Optimisation in Development Phase of Vehicles Related to Total Cost of Ownership

The AeroEfficient technology approach adopted by Bombardier and the multi-disciplinary optimization capabilities in modeFRONTIER takes into account constraints deriving from crash safety, structure, industrial design and ergonomic limits of the cabin to reduce aerodynamic drag. However, the most drag-efficient engineering concept presents weight concerns and high maintenance costs.

Aerodynamic Optimization of AC External Fuel Tanks at Airbus Defence and Space

Design a large external aircraft fuel tank ensuring the maximum range and endurance while minimizing the costs within a given time frame. Furthermore, due to the strict aircraft design standards, the flight conditions, static strength and other requirements should still be satisfied while meeting objectives and respecting the geometric constraints.
