The Phenomenon of Flow as Experienced by Classroom Teachers: Implications for Leadership Practice
The purposes of this qualitative study were to investigate the phenomenon of flow as experienced by classroom teachers and to determine the implications of the understanding of flow for leadership practice. The phenomenon of flow, as described by Mihalyi Csikszentmihalyi, is reported to be …

Theoretical and Experimental Studies of Structure Formation in Polymer Solutions Under Flow
A series of studies have been carried out with the goal of quantifying via molecular modeling the phenomenon of flow-induced structure formation in polymer solutions. Flow-induced stresses cause changes in the free energy of the polymer solutions and can eventually lead to phase separation. The …

Structure Formation and Crystallization in Two-Phase Polymer Blend Flows (Fibers, Polyethylene, Polypropylene)
Flow induced crystallization of high density polyethylene and polypropylene has been studied in a two-phase flow system using linear low density polyethylene as the carrier phase. Extensional stresses were generated under slow flow conditions by either of two methods: one involving flow past a …

Optimal design of municipal and irrigation water distribution systems
In two-dimensional flow, the point of flow separation from the surface coincides with the point at which the skin friction vanishes. However, in three-dimensional flow, the situation is much more complex and the flow separation is rarely associated with the vanishing of the wall shear stress except …

Characterisation and simulation of bidirectional multiphase flow in tubes
The bidirectional flow reversal phenomenon results in liquid accumulation, causes significant increase in pressure drop and therefore, the pumping power. In pipelines, this poses significant problem due to the presence of slug to churn, especially in producing gas wells. To understand the …

An experimental study of flow over a 6 to 1 prolate spheroid at incidence
In two-dimensional flow, the point of flow separation from the surface coincides with the point at which the skin friction vanishes. However, in three-dimensional flow, the situation is much more complex and the flow separation is rarely associated with the vanishing of the wall shear stress except …

Single polymer dynamics in semi-dilute solutions: linear and ring polymers
… Traditional characterization methods of polymeric materials rely on bulk level measurements that can provide useful information on material properties. However, these methods generally cannot access underlying molecular information, such as polymer conformation, distributions in …
