Analysis of the Lattice-Boltzmann-Based Code PowerFLOW: Flow Through a Parallel Confined Jet

PDF Version Also Available for Download.

Description

Recent advances in the development and practical implementation of the Lattice-Boltzmann (LB) method as applied to computational fluid dynamics (CFD) have spurred much interest. A simple literature search of this area yielded well over 200 articles published in the open literature since 1997. The key advantage of the LB method is the time-accurate simulation of complex flow phenomena that are intractable with traditional methods. Analysis of flow in a parallel confined jet (PCJ) has been performed using the commercial LB-based CFD code PowerFLOW (Exa Corporation, Lexington, MA, USA). Results are compared to both experimental data and numerical results given in ... continued below

Description

Recent advances in the development and practical implementation of the Lattice-Boltzmann (LB) method as applied to computational fluid dynamics (CFD) have spurred much interest. A simple literature search of this area yielded well over 200 articles published in the open literature since 1997. The key advantage of the LB method is the time-accurate simulation of complex flow phenomena that are intractable with traditional methods. Analysis of flow in a parallel confined jet (PCJ) has been performed using the commercial LB-based CFD code PowerFLOW (Exa Corporation, Lexington, MA, USA). Results are compared to both experimental data and numerical results given in the literature, and it was observed that PowerFLOW does very well in accurately emulating the PJC experimental data as compared to Reynolds-Averaged Navier-Stokes schemes. In addition, the inherently transient nature of the LB method allowed the analysis of time-dependent aspects of jet flows (e.g., flapping).
