Finite difference analysis of transient flow through a staggered bundle of cylinders L. Rorris, J. Rasoul, P. Anagnostopoulos, J. Ganoulis Department of Civil Engineering, University of Thessaloniki, Thessaloniki 54006, Macedonia, Greece ABSTRACT The finite difference method was used for the solution of laminar incompressible flow through a staggered bundle of five cylinders in the streamwise direction. The two-dimensional Navier-Stokes equations were solved, in the formulation where the two components of the fluid velocity and the pressure are the field variables. The pitch to diameter ratio was 1.5, corresponding to equilateral triangular arrangement. The Reynolds numbers considered, based on the inflow velocity and the cylinder diameter, ranged between 50 and 200. Velocity profiles, streamline patterns, vocticity and pressure distributions and shear stress and pressure coefficients around the cylinders are presented.
