The effects of mangrove forests on the flow structure in estuaries have been studied in this paper. An existing two-dimensional depth-integrated mathematical model has been refined to include both the effects of drag force induced by mangrove trees and the blockage effects on the mass fluxes through mangrove forests. To investigate the influence of mangrove trees on the flow structure two ideal...

A trisonic wind tunnel has been modified to improve its flow quality when operating at transonic speeds through perforated walls and side suctions. The usefulness of such a perforated wall, already known, is reduction of the blockage effect as well as the shock elimination. Two types of perforated walls have been used in this investigation. The first wall had a porosity of about 22% and the hol...

Sir Humphry Davy witnessed the first chlorine hydrate crystallizing in 1811. Couple of century later his discovery, natural gas hydrates has begun to play an important role in energy business. From being a mere chemical curiosity, they have proven to be a nuisance for the natural gas industry. The problem of hydrate induced blockage in “wet gas” flow systems has been widely reported and became ...

A huge number of deaths in the world are the direct or indirect consequence of a disease which is called atherosclerosis. The disease could be due to an artery blockage by the interaction of an externally second phase with a particle which is entered to the bloodstream. The effect of some most important physical and geometrical affecting parameters on the blockage time of a microchannel due to ...

Modeling of systems, for example, communication systems, involves identification of their basic components and interrelationships. This paper proposes a model of ethical systems based on the notion of flow. The flow of ethical rules, for example, ought not lie, is conceptualized to trigger the flow/blockage of other flows such as information flow. In this scheme different types of mechanisms ca...

boundary layer growth and hence displacement thickness are the key factors in shock position over aerodynamical surfaces at transonic regimes. since boundary layer growth is a function of free stream reynolds number and also of the transition location, the free stream reynolds number and also the other parameters involved in the boundary layer growth and its transition location are determinant ...

Five new mathematical triple fouling models were developed to explore the flux decline behavior during the microfiltration. The first model was developed by the assumption of the successive effects of standard mechanism, intermediate pore blockage and cake formation by using the standard blocking flux expression in the model calculations. The second and third models also obtained by the success...

Taking hydraulic punching test of Zhaozhuang Mine as engineering background, by comparing the field application effects different processes, relationship between coal moisture content around borehole blockage and gas extraction effect was monitored analyzed. The following conclusions were drawn: occurrence result comprehensive action slag particle size discharge capacity return water. Blocking ...

Blockage of water intakes by underwater ice formation during supercooling events is a widespread and common problem in northern regions winter. In this context, means deposition frazil growth platelet ice. happens when forms on the structural components intakes, particularly intake trash racks, decreasing area available for flow. This article evaluates potential solutions preventing blockage. T...
