Abstract The influence of mixture stratification on the development turbulent flames in a slot-jet configuration has been analysed using Direct Numerical Simulation data. Mixture was imposed at inlet by varying equivalence ratio between 0.6 and 1.0 with different alignments to reaction progress variable gradient: aligned gradients (back-supported), opposed (front-supported) misaligned gradients...

scoure is the removal of particle sediment which results variation of flow pattern. local scour is considered as one of the reasons of instability and ultimately failure of bridges.therefore, proposing some controlling methods to reduce this phenomenon is essential. in the study, effects of two types of squar and circular collar on a single cylindrical model have been investigated. in the next ...

Wormlike micellar surfactant solutions are encountered in a wide variety of important applications, including enhanced oil recovery and ink-jet printing, in which the fluids are subjected to high extensional strain rates. In this contribution we present an experimental investigation of the flow of a model wormlike micellar solution (cetyl pyridinium chloride and sodium salicylate in deionised w...
