✦ Synopsis

Finite element simulation of transient laminar ¯ow past an in-line tube bank is carried out using a velocity correction procedure. The two-dimensional unsteady Navier±Stokes and energy equations are solved using an explicit and a semi-implicit algorithm for a Reynolds number of 100, a Prandtl number of 0.7, and pitch-to-diameter ratios (PDR) of 1.5 and 2.0. The Galerkin weighted residual formulation is used for the discretization in space. Numerical ¯ow visuals are drawn, showing the time evolution of streamlines. Local and average Nusselt numbers, pressure, and shear stress distributions around the cylinders have also been determined. The results compare well with existing numerical simulations.
