Influence of microjets on flow development at supersonic mach numbers with sudden expansion
This paper presents the control of suddenly expanded flow using four microjets at the base recirculation zone for a diameter ratio of 1.8. Eight Mach numbers are considered for investigations from 1.25 to 3. The NPRs for which the tests were conducted were from 3 to 11. The duct length considered w...

description |
This paper presents the control of suddenly expanded flow using four microjets at the base recirculation zone for a diameter ratio of 1.8. Eight Mach numbers are considered for
investigations from 1.25 to 3. The NPRs for which the tests were conducted were from 3 to 11. The duct length considered was L = 10D to 1D. This article has shown only selected results when there is significant variation in the duct's flow field; only those cases are considered. For most of the cases, the flow remains identical with and without control. For Mach M = 1.25 to 2.5, the control results in a decline in the duct's pressure when the flow is within the
reattachment length. Later there is a progressive rise in the duct pressure. However, the trend is reversed at Mach M 3.0. The least duct stretches necessary intended for the stream to continue to relate to the pipe are L = 1D, 2D, and 3D for the study's Mach number. |
