Complex Pressure-Related Flow Phenomena in CFD

Complex Pressure-Related Flow Phenomena in CFD

Complex Pressure-Related Flow Phenomena in CFD

CFD enables the visualization and understanding of complicated flow phenomena that occur in a wide range of complex flow problems. Many of these phenomena are related to the occurrence of abrupt or unfavourable pressure field changes in these flows. Flow separation, shock, wake, and cavitation are examples of these pressure-related complex phenomena.

Through a simple and moderately technical approach, this course discusses the underlying causes of these phenomena and the care that must be taken to address them in CFD simulations.

This course is perfect for analysts and managers who may have limited exposure to fluid dynamics or need a fluid dynamics refresher as it relates to CFD.
