Compared to the long and expansive history of computational fluid dynamics (CFD) influence in the aerospace and automotive industries, bioengineering only recently has begun to reap potential benefits from CFD technology. This technology lag was mainly due to a slow migration of experienced CFD researchers into the biomedical field and the sundry physiologic complexities associated with biofluid problems. While CFD offers the potential for gaining tremendous insight into biomedical fluid dynamics, there remains a disconcerting general over-estimation of current CFD capabilities for biomedical applications, particularly in the areas of predictive blood damage modeling and device design optimization. Drawing from over 10 years of experience in CFD analysis and design of rotary blood pumps, this work provides a broad critique of available CFD technologies as applied to biofluid simulation. The topics covered include: quality standards for biofluid simulation; current state of numerical models of blood damage; latest developments in fluid-structure interaction and CFD-based design optimization; a cross-section of sample results for both academic and industrial devices; and the outlook for future promising directions of CFD technology.
