Uncertainty Analysis of Quasi-Two-Dimensional Flow Simulation in Compound Channels with Overbank Flows

Scaling of near-wall flows in quasi-two-dimensional turbulent channels.

The law of the wall and the log law rule the near-wall mean velocity profile of three-dimensional turbulent flows. These well-known laws, which are validated by legions of experiments and simulations, may be universal. Here, using a soap-film channel, we report the first experimental test of these laws in quasi-two-dimensional turbulent channel flows under two disparate turbulent spectra. We fi...

mean flow and turbulence in compound channels with vegetated floodplains

the study of flow in compound channels with vegetated floodplains is essential to assessing the development of the stage-discharge relationship and sediment and pollutant transport. the present study experimentally investigated mean flow and turbulence characteristics in a prismatic compound channel. the experimental program consisted of vegetated and non-vegetated floodplains with different re...

critical discourse analysis of two political speeches in light of bakhtins dialogism

چکیده گفتگوگری باختین نظریه ای است که به تفاوت ها احترام گذاشته و گفتگو را ارج می نهد. رشته های مختلف علوم انسانی همواره از این نظریه بهره جسته اند. با وجود این تنها مطالعات اندکی در زمینه تجزیه و تحلیل نقادانه کلام به نظریه گفتگوگری پرداخته اند. پنداشت تحقیق حاضر بر آن است که احترام به حقوق دیگران از طریق فراهم آوردن شرایط یکسان برای بیان نظریات مختلف یکی از مهمترین مشترکات تحلیل انتقادی گفتم...

Numerical Simulation and Optimization of Heat Transfer in Reciprocating Flows in Two - Dimensional Channels

Hydrodynamic interactions in ribbon channels: from quasi-one-dimensional to quasi-two-dimensional behavior.

We present a study of the dynamics of confined suspensions whose dimensionality is intermediate between quasi-one-dimensional and quasi-two-dimensional (q2D) using microfluidic channels of various widths. The crossover between the two limiting behaviors is found to occur to different extent for different dynamic correlations between a pair of particles. In particular, the transverse coupling di...
