This article employed numerical methods to investigate the aerodynamic, thermal, and infrared characteristics of last-stage turbine swirl on a two-dimensional convergent divergent (2D-CD) exhaust system with an afterburner under varying bypass ratios. The research results indicate that diminishes thrust coefficient flow 2D-CD afterburner. At ratio 0.2, decrease by 0.65% 1.07%, respectively. When is relatively small, leads in temperature heat shield. Conversely, when large, opposite occurs....
Abstract This paper describes further development and testing of the Renormalization Nonuniform Coarsening (RNC) scale up algorithm, which was recently introduced in Ref. 13. RNC combines nonuniform coarsening with upscaling absolute relative permeabilities to provide coarsened descriptions two-phase immiscible flow. We diagnose a known bias algorithm used RNC. An unbiased alternative is incorporated into up. The modified tested on displacements through two dimensional cross sections...
A subgrid turbulence model for the lattice Boltzmann method is proposed high Reynolds number fluid flow applications. The method, based on standard Smagorinsky and a single-time relaxation incorporates advantages of handling arbitrary boundaries easily implemented parallel machines. applied to two-dimensional driven cavity studying dynamics dependence structures. substitution other models, such as dynamic model, in framework LB discussed.
