Increasing run time as flow behavior index (n) decreases in Power Law fluids
I am simulating the Poiseulle flow of Power low fluids by DualSPHysics.
I am using HBP model to stimulate non-Newtonian behavior of Power low fluids by setting the appropriate value of m and n parameters in HBP model. When n ≠ 1 and m = 0 the HBP model reduces to a Power Law model.
I am observing an issue that with the same number of particles, with the same IDP by decreasing flow behavior index (n) the run time increases.
I will be appreciated if someone can explain to me what is the reason behind increasing run time with the same IDP.
Happy new year in advance
