We have introduced evolutionary game dynamics to a one-dimensional cellular-automaton to investigate evolution and maintenance of cooperative avoiding behavior of self-driven particles in bidirectional flow. In our model, there are two kinds of particles, which are right-going particles and left-going particles. They often face opponent particles, so that they swerve to the right or left stocha...

Controlling the flame shape and its liftoff height is one of main issues for oxy-flames to limit heat transfer solid components injector. An extensive experimental study carried out analyze effects co- counter-swirl on flow patterns non-premixed stabilized above a coaxial injector when both inner fuel annular oxidizer streams are swirled. A swirl level greater than 0.6 in stream shown yield com...

Isosurfacing, by itself, is a common visualization technique for investigating 3D vector fields. Applying texturebased flow visualization techniques to isosurfaces provides engineers with even more insight into the characteristics of 3D vector fields. We apply a method for producing dense, texture-based representations of flow on isosurfaces. It combines two well know scientific visualization t...

Abstract Boundary layer ingestion (BLI) offers potential reductions in fuel burn and emissions. The propulsive fuselage concept features an aft fan that ingests the 360 deg boundary layer. A critical condition for this configuration occurs when a sideslip angle arises between aircraft longitudinal axis freestream velocity. flow combination with airframe generates inlet distortion depends on dir...

The vortex/swirl flowmeters are meant to measure the flowrate based on the measurement of the flow frequency. Due to the frequency-dependent computation of the flowrate, noflow pulsation causes a false positive, i.e., it indicates certain amount of flowrate when actually there is no flow. This happens when for example, the valves of the flow pipe are closed causing no flow, but some pumps are w...

The interaction of a droplet with swirling airstream is investigated experimentally using shadowgraphy and particle image velocimetry techniques. In swirl flow, the experiences oppose-flow, cross-flow co-flow conditions depending on its ejection location, velocity strength, which results in distinct morphologies as compared straight airflow situation. We observe new breakup phenomenon, termed ‘...

This study focuses on the development of an internal potential flow solution in context a hemispherically bounded cyclonic chamber. The analysis proceeds from Bragg–Hawthorne equation, which is quite effective treatment steady, inviscid, and axisymmetric flows when expressed terms streamfunction. Once streamfunction obtained, other properties are readily deduced; these include principal velocit...

In this paper a detailed model of a VVER1000 reactor pressure vessel (RPV) with the extension of simplified primary loops is presented (Loop model). The primary loop components like steam generators and pumps are modelled by the outer shapes and additional source terms for energy and momentum exchange. The RPV model part is tested without primary loops and compared with former results obtained ...
