Are current turbulence modeling practices addressing industry's needs for electronics thermal design?

摘要

Since the 1990's, computational fluid dynamics (CFD) has been widely adopted in the electronics industry for the thermal design of electronic products. Its advantages in terms of product improvements and enhanced productivity of design analysis, are undisputed. However, the industry has also experienced that incorrect product design decisions can be taken as a result of inaccurate CFD predictions, with consequences ranging from reduced product performance and reliability, to catastrophic field failure. Consequently, understanding and minimizing CFD prediction errors is a major concern to ensure a return on capital, software and human resource investments in the thermal design process.
