Petrobras Designs the P-55 platform using modeFRONTIER
In 2014 Petrobras, a state-owned publicly traded Brazilian multinational energy corporation headquartered in Rio de Janeiro, Brazil, launched their P-55 offshore platform, which was initially sized using modeFRONTIER. In order to tackle the complex problem of multiple variables, constraints and objectives, as well as a desire for a rational approach to the design process, Petrobras turned to modeFRONTIER to help them with the optimization study.
Optimization of a Turbo Charger Compressor at BorgWarner using AxCent and modeFRONTIER
This work presents a numerically optimized design approach to turbo charger radial compressor development for commercial diesel applications. The design optimization includes both aerodynamic and structural components, combined via a “loosely coupled” iterative procedure. The primary goal of the design is to maximize total to static efficiency at various operating conditions, while also preserving or expanding the overall operating range of the compressor, and doing so with a structurally sound geometry.
