CFD Simulation Exercises

(Updated: July, 2017)

Continuing my CFD simulation studies, this time, I focused on compressible fluids.

The flue gas is drawn by the gas blower from the combustor to the stack.

I found that compressible fluids, which have changing fluid density, take significantly longer for the model to converge compared to incompressible fluids, which have constant fluid density.

Next, I plan to tackle non-Newtonian fluids, such as slurry. Setting up the model for these fluids is challenging because their viscosity depends on the fluid's velocity. Unlike Newtonian fluids, the relationship between the stress applied to non-Newtonian fluids and the rate of strain is not proportional. This means that their flow behavior cannot be described by a single constant viscosity value. Stay tuned for updates on this exciting and complex endeavor!
