✦ Synopsis

Direct numerical simulations of the ¯ow ®eld of an element of banks of impinging axial and radial slot jets for different Reynolds number are presented. Simulations have been obtained from the solution of the Navier±Stokes equations. Results show for the chosen geometry a transition from steady to periodic to chaotic ¯ow with increasing Reynolds number. The transition Reynolds number is nearly 50% smaller for the radial jet than for the axial jet. Period doubling has been observed for both cases, but only the radial jet shows periodic windows of chaos.

The three-dimensional turbulent impinging square twin-jet flow with no-crossflow is analyzed by employing the computational fluid dynamics (CFD) code PHOENICS. The SIMPLEST algorithm and the Jones-Launder k-m two-equation turbulence model are used to simulate the strong turbulence of the three-dimen
