| Abstract: | In this paper,
the effect of the central jet width in the flow field created due to the
interaction of two turbulent jets at impingement angles of a equal to 30° and 45° and a central jet is described. The investigation is carried out
for velocity ratios (UC/UO)
of 1.0, 2.0 and 3.0, where UC
and UO are the velocities
in the central and the outer jets respectively. It is seen from the static
pressure analysis that the extents of various recirculation zones are altered
significantly when the velocity ratio UC/UO changes from 1.0 to 2.0 and when
the central jet width ratio increase from w/2B=0.064 to 0.127 in both the cases ( =30° and 45°). From the analysis of mean velocity, it is found that the flow
structure is significantly different when the width ratio changes from 0.064 to
0.127. |
