Water pump design: Geometry optimization for a shrouded impeller

For CFD-driven shape optimization of water pumps with shrouded impellers, it’s essential to have an efficient variable-geometry model defined by a set of relevant parameters (design variables). This case-study example focuses on geometry modeling of a typical water pump, with the goal of attaining maximum flexibility in shape variation and fine-tuning.

To begin, the geometry was set up in CAESES (CAE System Empowering Simulation), the software platform from FRIENDSHIP SYSTEMS that helps engineers design optimal flow-exposed products. CAESES provides simulation-ready parametric CAD for complex free-form surfaces, and targets CFD-driven design processes. Its specialized geometry models are ideally suited to automated design exploration and shape optimization. Continue reading

Hull form optimization of a mega-boxer

MSC Danit. Source: DSME

With a capacity of 14,000 TEUs, an overall length of 365.5 meters and a deadweight of 165,517 metric tons, the MSC Danit became the world’s largest container vessel when finished by Korean shipyard Daewoo Shipbuilding & Marine Engineering (DSME). A New Panamax design, the ship offers excellent performance despite its record size. DSME used FRIENDSHIP SYSTEMSCAESES / FRIENDSHIP-Framework (FFW) for variation and optimization of proven parent ships to arrive at a design with maximum performance and efficiency. The final hull displayed less than 50% of the wave resistance of the baseline design, and the hydrodynamic optimization in CAESES/FFW had a favorable effect on propulsion performance.

Design exploration vs. design optimization

Automating the search for solutions to engineering problems can take either of two broad approaches: design exploration or design optimization. Practitioners making technology choices need to understand which tools do one, which do the other, and which approach best fits their needs. A global roster of commercially available design exploration and optimization software appears at the end of this post. Continue reading
