The Effects of Scales on Modeling of Flow Patterns Over Spillway [PDF]

open access: yesمجلة جامعة النجاح للأبحاث العلوم الطبيعية
Climate changes leading to extreme events when the occurrence and intensity of severe phenomena have impeded the development and rehabilitation of hydraulic infrastructure, such as weirs and spillways according to these new conditions. The scale physical

Accuracy of boundary layer treatments at different Reynolds scales

open access: yesOpen Engineering, 2020
Resistive forces associated to boundary layers (‘friction’) are usually out of scale in physical models of hydraulic structures, especially in the case of hydraulically smooth walls, generating distortions in the model results known as scale effects ...
