Numerical Analysis of Seepage in Steady and Transient Flow State by the Radial Basis Function Method [PDF]

open access: yesNumerical Methods in Civil Engineering, 2023
Here, the meshless method with the finite difference method has been used to discretize the governing equations of the seepage phenomenon from under the dam in the steady and transient flow.

Contaminant transport analysis under non-linear sorption in a heterogeneous groundwater system

open access: yesApplied Mathematics in Science and Engineering, 2022
In this study, a one-dimensional non-linear advection–dispersion equation subject to spatial–temporal dependent advection and dispersion coefficients is solved for a heterogeneous groundwater system.

Applying Simultaneously Monte Carlo Method and Dimension Reduction in Calculating the Reliability of Water Column Separation Phenomenon [PDF]

open access: yesمجله مدل سازی در مهندسی
Network reliability is one of the main effective indicators for designing and managing water distribution networks in normal or critical operating conditions. Occurrence of transient flow and sometimes the water column separation phenomenon is one of the

Caracterización y mitigación del flujo intermitente en sistemas de recolección multifásicos bajo condiciones dinámicas

open access: yesRevista Fuentes El Reventón Energético, 2015
Challenges associated to multiphasic fl ow are as old as the petroleum industry itself. in many oil and gas fields with multiphasic fl ow lines, production instability due to severe slugging is their main fl ow assurance issue.

Numerical simulation of a supersonic ejector for vacuum generation with explicit and implicit solver in openfoam [PDF]

open access: yes, 2019
Supersonic ejectors are used extensively in all kind of applications: compression of refrigerants in cooling systems, pumping of volatile fluids or in vacuum generation. In vacuum generation, also known as zero-secondary flow, the ejector has a transient

Termite-inspired metamaterials for flow-active building envelopes

open access: yesFrontiers in Materials, 2023
In this article we investigate the performative potential of reticulated tunnel networks to act as drivers for selective airflows in building envelopes and thereby facilitate semi-passive climate regulation.

Application of Spatial Time Domain Reflectometry for Investigating Moisture Content Dynamics in Unsaturated Loamy Sand for Gravitational Drainage

open access: yesApplied Sciences, 2021
The strength of unsaturated soil is defined by the soil water retention behavior and soil suction acting inside the soil matrix. In order to obtain the suction and moisture profile in the vadose zone, specific measuring techniques are needed. Time domain
