ANSYS Convergence Webinar Series 2013: Fluid Dynamics

Three companies’ design teams solved design challenges using ANSYS CFD simulation tools: Sub-Zero, 3M and Navistar.

Challenges in Designing Appliances with Luxury Features
Anderson Bortoletto, Sub-Zero
One challenge in designing Sub-Zero appliances is to incorporate luxury features while meeting strict energy consumption targets in a timely and cost-effective manner. The company applied a simulation-based design process to significantly reduce development costs for next-generation glass doors for wine coolers; reduce energy consumption of an ice dispensing solution; launch side-by-side refrigerators to market faster; and develop air flow grills for trouble-free product installation.

Computer-Aided Engineering of an Advanced LED Light Bulb
Karl Geisler, 3M
Solid-state light sources, such as LEDs, are the wave of the future. While unique characteristics will be exploited to produce new luminaire types and paradigms, the massive installed base of traditional fixtures demands adaptation. Since LED junction temperature directly impacts energy efficiency, output spectrum and device lifetime, thermal management is a key linkage in the interdependence of application requirements, design parameters and performance characteristics. Comprehensive system modeling is invaluable in the search for optimum designs. This session highlights the use of ANSYS Icepak in the design of an innovative new LED light bulb, the 3M LED Advanced Light.

Underhood Front-End Flow Analysis
Qin Yang, Navistar
The design and optimization of cooling modules in heaving ground vehicles are crucial to underhood thermal management — and ultimately engine performance and reliability. Optimization sometimes call for many design iterations, especially during early design phase, so quick turnaround is important. This can be achieved by rapid meshing and fast case setup. This presentation introduces best practices developed at Navistar for Underhood Front-End Flow Analysis using ANSYS Fluent for for meshing and solving steady-state flow.
