Computational Fluid Dynamics

The world of Computational Fluid Dynamics (CFD) is sometimes seen as a black art, associated with rocket scientists and wind tunnels. But in reality, CFD is a vital part of many mechanical engineering projects. At its core, CFD is the process of simulating the flow of a gas or fluid in a system. CFD makes it possible to avoid the complex equations needed in traditional fluid dynamics. Its flexibility lies in the ability to model an infinite range of flow systems.

Optimization equals reduced costs

The use of CFD analysis in your designs directly translates into reduced prototyping costs and shorter lead times, for much of the analysis can be done without manufacturing expensive prototypes. From the flow of oxygen in a car engine to the modeling of global ocean currents, CFD plays a key role in how today's new technology is engineered.

Case Study: PediaFlowTM VAD

LaunchPoint engineers are currently designing the PediaFlowTM ventricular assist device in conjunction with the University of Pittsburgh. Because we place much value in System Engineering and efficient design, our CFD expertise plays a central role in the design of the PediaFlowTM. In order to minimize energy requirements and maximize the reliability of the device, it is necessary for us to analyze and optimize the blood flow in and around the centrifugal heart pump. Some issues we are overcoming with the help of CFD include:

  • Optimizing the flow of blood in and around the pump
  • Preventing cavitation in the blood
  • Electronic cooling of the implanted pump
  • The design of a ventricular cannula

All CFD research is led by Dr. Jingchun Wu. His expertise as a CFD consultant is available to any of LaunchPoint's clients and partners. For more information or to request a quote, please contact us today!
