Discussion: “Flow Regimes in Curved Subsonic Diffusers” (Fox, R. W., and Kline, S. J., , ASME J. Basic Eng., 84, pp. –)Author: C. J. Sagi, N. Turgeon, J. P. Johnston. Flow characteristics in a large area ratio curved diffuser (AR = , Δβ = 90°, AS = ) have been experimentally evaluated with splitter vanes installed at different angles to the flow at the inlet of the diffuser. The splitter vanes deflect the flow towards the convex wall and simultaneously increase the turbulence intensity. A marked improvement in flow distribution inside the Cited by: An extension and refinement of the work of Moore and Kline (NACA TN ) is presented for the flow regimes found in straight-walled diffusers. A systematic map of flow regimes in curved diffusing. Flow Regimes in Curved Subsonic Diffusers. A systematic map of flow regimes in curved diffusing passages is presented, in steps of ten degrees, for a range of flow turning angles from 0 to
The first systematic studies on 2-D curved subsonic diffusers were carried out by Fox & Kline . The centerline of the diffuser was taken as circular with a linearly varying area distribution normal to the centerline. They established a complete map of flow over a . Abstract. The effect of the turning angle on the flow and performance characteristics of long S-shaped circular diffusers (length-inlet diameter ratio, L/D i = ) having an area ratio of and centre-line length of mm has been established. The experiments are carried out for three S-shaped circular diffusers having angles of turn of 15°/15°, °/° and 30°/30°.

In the present investigation the distribution of mean velocity, static pressure and total pressure are experimentally studied on an annular curved diffuser of ° angle of turn with an area ratio of and centerline length was chosen as three times of inlet diameter. The experimental results then were numerically validated with the help of Fluent and then a series of parametric. Diverging subsonic flow: ∂A s > 0 and M flow, or ∂A s > 0. If the flow is subsonic, M 0. That is, the pressure must increase in the direction of a subsonic diverging flow. Fox RW, Kline SJ () Flow regimes in curved subsonic diffusers.
