On the effect of the refinement of the roughness description in a 2D approach for a mountain river: A case study
(2021)
The prediction of water levels in rivers is important to prevent economical as well as human losses caused by flooding.
Hydraulic models are commonly used to predict those water levels and take actions to mitigate flooding ...
Análise de coeficientes em fórmulas empíricas de perda de carga contínua em tubos de PVC
(Universidade Federal de Santa MariaBrasilEngenharia AgrícolaUFSMPrograma de Pós-Graduação em Engenharia AgrícolaCentro de Ciências Rurais, 2021-12-03)
The continuous pressure drop in the pressurized irrigation system is an extremely
important factor that must be taken into account when designing hydraulics. For your
estimation to be performed correctly, you need precise ...
Differences Between Effective and Physical Roughness Parameter- A Headwater Mountain River Experiment
(IEEE, 2021)
One-dimensional hydrodynamic models (HM) are widely used in the hydraulic modeling of rivers and channels. The result obtained with this type of model depends largely on correct estimation the roughness parameter. The value ...
Failure analysis as a tool to optimize the design of a ring on disc tribotest investigating the role of surface roughness
(ElsevierOxford, 2015)
The influence of the surface roughness of pearlitic grey cast iron discs on the formation of tribofilms and the evolution of the friction coefficient during a ring on disc tribotest with the addition of magnetite and ...
Desenvolvimento de método para a análise quantitativa da rugosidade de substratos cerâmicos argilosos
(Universidade do Vale do Rio dos Sinos, 2021-08-26)
The diversification of materials used as substrates in Civil Construction hinders the standardization of building systems, increasing the probability of pathological manifestations. An example of this is the detachment of ...
