Jet in cross flow is an important issue in engineering practice, for example, it is used to improve turbine efficiency in film cooling. In this study, the large eddy simulation and the spectrum analysis are employed to analyze the vortices in a jet i

In the modeling of vegetated flows an efficient approach is to solve the Double Averaged Navier Stokes (DANS) equations, which are obtained from the spatial and temporal averaging of the Navier Stokes equations. The resistance effects of vegetation a

In this work we investigate experimentally and numerically the flow structure around foliaged plants deployed in a channel with gravels on the bed under submerged and barely submerged conditions. Velocity and Reynolds stress were measured by using a

The drag induced by flow through vegetation is affected by the velocity, shape of vegetation stems and wake interference among stems. To account for the interference effects, previous works generally related the bulk drag coefficient of vegetation to

Free-surface flows over patchy vegetation are common in aquatic environments. In this study, the hydrodynamics of free-surface flow in a rectangular channel with a bed of rigid vegetation-like cylinders occupying half of the channel bed was investiga

A novel Double Averaged Navier-Stokes equation model has been developed to simulate flows in vegetated open channels. Turbulence is modelled by the Spalart-Allmaras closure with a modified length scale, which is dependent on a zero-plane displacement

The hydraulic interception efficiency of a gully grating decreases with the steepness of the road on which it is installed. This can lead to a higher potential for flooding at the downstream area of a steep road. In this study, the hydraulic inceptio
