When two-fuid models are applied for gas-fluidized beds , it is observed the numerical stability of the model is so sensitive to the value of the coefficient of normal restitution. why and how can handle it?
Thanks
Vitalii, thank you so much!
You also need to consider the interfacial pressure difference and you need to do a characteristic analysis to make sure the combination is well-posed.
Thank you for your comment, but if we use compressible TFM, we still need to consider the interfacial pressure difference?
It's up to you, but the ill-posed condition is an incompressible problem.
