Optimization of Orifice Geometry for Cross-Flow Mixing in. For a given geometry an ultimate upstream penetration depth of the counter flow jet has been estimated to be approximately diameter of the cylindrical duct. This study was motivated by a goal to understand the mixing and emissions in the rich-burn/quick-mix/lean-burn combustor scheme that has been proposed to minimize the formation of oxides of nitrogen (N O x) in gas turbine combustors. The study reported in this paper was a reacting jet-in-crossflow experiment at atmospheric pressure in a cylindrical duct. a duct or a system fitting such as a valve. Gas flow conductance is thus analogous to electrical conductance, with pressure difference being the analogue of voltage differ­ ence and Q the analogue of current. The reciprocal of conductance (resistance or impedance, Z = 1/C) could equally wel1 be used; however, conductance has come into.

Optimization of circular orifice jets mixing into a heated cross flow in a cylindrical duct To examine the mixing characteristics of circular jets in an axisymmetric can geometry, temperature measurements were obtained downstream of a row of cold jet injected into a heated cross stream. The objective was to obtain uniform mixing within one duct radius downstream of the leading edge of the jet.
