Choking and High-speed Flow
Tuesday December 17th, 2pm MST
When flow velocities get big, things gets interesting. Above Mach=0.1, the bulk fluid "sees" a wall that is warmer than the structural temperature due to deceleration within the boundary layer. Above Mach=0.3, kinetic energy changes cease to be negligible. And of course, nothing moves faster than Mach=1.0 for internal flow. When you also add in changes in flow area, or changes in phase ... well, let's just say that doesn't simplify anything.
This webinar will introduce you to the phenomena involved, with a focus on the FloCAD modeling parameters available and their associated correlations and assumptions.

Turbomachinery and Rotating Passages (Secondary Flows)
Thursday December 19th, 2pm MST
Are turbomachines a component in your system, and you'd like to treat them as a "black box"?
Or are they the focus of your work, and the cycle is just a boundary condition to you?
Either way, this webinar will have something to offer you. Each type of turbomachine will be covered: pumps and fans, positive and variable displacement compressors, and turbines (whether gas or hydraulic). Methods for modeling systems like turbochargers and turbopumps will be introduced. Tools for handling spinning flow passages and rotating cavities will be presented.
