Better thermal design means better efficiency
The strategic use of computational fluid dynamics can speed the development of high-tech products. BORIS MAROVIC, JOHN PARRY MENTOR GRAPHICS CORP. TRADITIONALLY, analysis using computational fluid dynamics (CFD) took place late in the design process once changes to part geometries had pretty much stopped. But CFD is starting to be applied at earlier stages of […]
