A method based on microjets is implemented to control the flow properties in a convergent-divergent nozzle undergoing sudden expansion. Three different variants of this active technique are explored numerically by means finite-volume for compressible fluid flow: with first one, at base, second wall, while third one may be regarded as combination other two variants. When jets over-expanded, not ...

FlowExpansion is a network design problem, in which the input consists of flow and set candidate edges, may be added to network. Adding incurs given costs. The goal determine cheapest edges that, if added, allow demands satisfied. variant Minimum-Cost Flow problem with non-linear edge

Simulations of three-dimensional laminar forced convection in a plane symmetric sudden expansion are presented for Reynolds numbers where the flow is steady and symmetric. A swirling ‘‘jetlike’’ flow develops near the sidewalls in the separating shear layer, and its impingement on the stepped wall is responsible for the maximum that develops in the Nusselt number adjacent to the sidewalls and f...

This paper aims to assess the control mechanism's efficiency and flow pattern in pipe. The was investigated for Mach numbers M = 1.25, 1.3, 1.48, 1.6, 1.8, 2.0, 2.5, 3.0 a step height of 3 mm.
