STUDY ON FLOW OF POWER-LAW FLUID THROUGH AN INFINITE ARRAY OF CIRCULAR CYLINDERS WITH IMMERSED BOUNDARY-LATTICE BOLTZMANN METHOD

ABSTRACT
A direct forcing method for the simulation of particulate flows based on immersed boundary-lattice Boltzmann method is used to study the flow of power-law fluid through an infinite array of circular cylinders with cylinder separations of 20a (a is the cylinder radius) with laminar shedding behind cylinders. Time averaged drag coefficient, maximum of lift coefficient and Strouhal number are given out with the power-law index in the range of 0.4 ≤ n ≤ 1.8 and Re in the range of 50 ≤ Re ≤ 140.
