  4. Abstract:
  5. In the present study, the fluid characteristics of triangular turbulent jet flow are considered experimentally and numericafly. The results of spatially developed three- dimensional jet, issued from an equilateral triangular nozzle are presented. The jet is discharged to both bounded and unbounded domains. Because of the wind tunnel set up restrictions, the experimental study has done just for the bounded domain. The hot-wire anemometry is used for experimental study. A numerical method employing control volume approach with collocated grid arrangement which couples the velocity and pressure fields with SIMPLEC algorithm is introduced to discrete the governing equations of fluid flow. The turbulent stresses are approximated using k- model. Both bounded and unbounded domains have been studied using a numerical code. The velocity field is presented using profi'es and contours. Comparison of numerical and experimental results for the bounded domain shows a good agreement. Copyright © 2008 by ASME
