Investigation of Undular Hydraulic Jump over Smooth Beds
Undular hydraulic jumps are illustrated by a smooth rise of the free surface followed by a train of stationary waves. They are sometimes experienced in natural waterways and rivers. The characteristics of undular hydraulic jumps are studied here. The height, amplitude and the main characteristics of undular jump is depended on the upstream Froude number and aspect ratio. The experiments were do...
متن کاملhydraulic jump properties in irrigation canals with corrugated bed
abstract one of the most frequently encountered cases of rapid varied flow is the hydraulic jump. it occurs when a supercritical open channel flow changes into sub critical flow. in the present research, the experimental study of the hydraulic jump on seven sinusoidal corrugated beds with different wave steepness. the wave steepness of sinusoidal corrugated beds is in the range of 0.1667 to 0.7...
متن کاملAnn Model for Prediction of Length of Hydraulic Jump on Rough Beds
Hydraulic jumps have immense practical utility in hydraulic engineering and allied fields, such as energy dissipater to dissipate the excess energy of flowing water downstream of hydraulic structures (spillways and sluice gates), efficient operation of flow measurement flumes, chlorinating of wastewater, aeration of streams which are polluted by biodegradable wastes and many other cases. The le...
متن کاملNumerical simulation of a turbulent hydraulic jump: Characterization of the free interface and large bubble structure
Bubble generation is a ubiquitous and complex phenomenon occurring as a result of non-linear behavior of the free surfaces. Plunging breakers, spilling breakers and plunging jets are just a few scenarios where bubble generation occurs. Due to its complexity and our lack of complete understanding of this phenomenon, the models developed in the literature are far from being predictive (Moraga et ...
متن کاملCharacteristics of Hydraulic Jump
The effect of an abruptly expanding channel on the main characteristics of hydraulic jump is considered experimentally. The present study was made for supercritical flow of Froude number varying between 2 to 9 and approach to expanded channel width ratios 0.4, 0.5, 0.6 and 0.8. Physical explanations of the variation of these characteristics under varying flow conditions are discussed based on t...
متن کاملNumerical simulation of effect of non-spherical particle shape and bed size on hydrodynamics of packed beds
Fluid flow has a fundamental role in the performance of packed bed reactors. Some related issues, such as pressure drop, are strongly affected by porosity, so non-spherical particles are used in industry for enhancement or creation of the desired porosity. In this study, the effects of particle shape, size, and porosity of the bed on the hydrodynamics of packed beds are investigated with three ...
