Title Both LES and k-e turbulence-treatment in CFD-approaches for creation of the database on flare-stacks flame-behaviour
Date 2009
Description There is an emerging importance to understand and to "map" the reacting complex-flows of the (larges-cale) flare-fires. In this study, the influence of the atmospheric events onto the flame-behaviour, has a start-up in investigation, by watching the development of the temperature-, velocity- and irradiance-fields as combustion-consequence of flared hydro-carbons. Heat radiation of the flame and the gaseous products of such non-premixed combustion (NPC) depend both on wind-condition as well as on the geometrical characteristics of the "torch". In this very study, we focused so far our interest by observing the top (with three pilots) of the API-537-standard-flare. Particularly in this report, we relied on the accuracy of the CFD-investigation tool (proven in earlier numerical experiments) while choosing the best of benefits of the both k-emodel (for treatment of turbulence in case of a steady-state investigation) and LES-approach in case of time-dependent numerical observations. So gained data on influence of the atmospheric changes onto the characteristic of the flare-fires is serving our aim: to have a "closer look" at such large-scale fires being under "disturbing" factors; and - by creating possible data-base - setting so further mosaic stone in a map of the crosstalk between the large-scale (reacting) complex flows, the flare-geometry and atmospheric circumstances where they occur.
