Using the rational relationship, established by the authors in a previous study that links the properties of critical flow and normal flows, the present investigation is related to the critical state of the flow in a rectangular-shaped channel. The main o... see more

The functional y(yc;m;S0;e;n) = 0 relationship has been well defined and theoretically established for the triangular-shaped channel, where ycis the critical depth, m is the side slope, S0 is the channel bottom slope, e is the absolute roughness, and n is... see more

The objective of this work is to propose a new approach to the calculation of the linear dimension of a rectangular channel at critical flow, whose internal walls are characterized by the relative roughness . The calculation takes into account the effect ... see more

Proper sizing of a channel, whatever its shape depends on the knowledge and mastering of the varied flow that occurs in it. This is, in particular, the case of the triangular channel on which the present study is focused. In the field of gradually varying... see more

Long Hauler Covid-19 is a condition that describes a person who has recovered from Covid-19 and is declared with a negative PCR smear 2 times but still feels signs and symptoms for a longer period of time, even severe and critical symptoms. Most cases com... see more

This study constitutes the second part of a first study devoted to the critical flow in a smooth circular conduit. The first study published on this subject showed that two critical states occur in a circular conduit for a given diameter D and slope S0. T... see more

The present work numerically investigates the flow field in a cubical cavity driven by a lid rotating about an axis passing through its geometric center. Behaviour of core flow and secondary vortical structures are presented. Grid-free critical Reynolds n... see more

In a circular conduit of diameter D and of a given slope S0, two critical states of the flow may occur for two different discharges. The first one is observed at shallow depths while the second one settles down at greater depths. This statement is the res... see more
