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 oundary-lattice Boltzmann method is used to study the flow of powerlaw luid through an infinite array of circular cylinders with cylinder separations f 20a (a is the cylinder radius) with laminar shedding behind cylinders. Time veraged drag coefficient, maximum of lift coefficient and Strouhal number are iven out with the power-law index in the range of 0.4 ≤ n ≤ 1.8 and Re in the ange of 50 ≤ Re ≤ 140.
