A parametric sensitivity analysis of numerically modelled piston-type filling and emptying of an inclined pipeline with an air valve
(BHR Group Limited, 2018)
Filling and emptying operations should be planned by engineers in operational stages to prevent a system failure depending on reaching extreme low pressure values. In this sense, a compression of an air pocket produces ...
Hydraulic modeling during filling and emptying processes in pressurized pipelines: a literature review
(Taylor and Francis Ltd., 2019)
Filling and emptying processes are common maneuvers while operating, controlling and managing water pipeline systems. Currently, these operations are executed following recommendations from technical manuals and pipe ...
Computational fluid dynamics for sub-atmospheric pressure analysis in pipe drainage
(Taylor and Francis Ltd., 2019)
The occurrence of sub-atmospheric pressure in the drainage of pipelines containing an air pocket has been known as a major cause of several serious problems. Accordingly, some system malfunction and pipe buckling events ...
Transient phenomena during the emptying process of a single pipe with water–air interaction
(Taylor and Francis Ltd., 2019)
Emptying pipelines can be critical in many water distribution networks because subatmospheric pressure troughs could cause considerable damage to the system due to the expansion of entrapped air. Researchers have given ...
Subatmospheric pressure in a water draining pipeline with an air pocket
(Taylor and Francis Ltd., 2018)
An air pocket’s behaviour inside of a pipeline during transient conditions is of great importance due to its effect on the safety of the hydraulic system and the complexity of modeling its behaviour. The emptying process ...
Backflow air and pressure analysis in emptying a pipeline containing an entrapped air pocket
(Taylor and Francis Ltd., 2018)
The prediction of the pressure inside the air pocket in water pipelines has been the topic for a lot of research works. Several aspects in this field have been discussed, such as the filling and the emptying procedures. ...
Rigid water column model for simulating the emptying process in a pipeline using pressurized air
(American Society of Civil Engineers (ASCE), 2018)
This paper presents a mathematical model for analyzing the emptying process in a pipeline using pressurized air. The rigid water column model (RWCM) is used to analyze the transient phenomena that occur during the emptying ...
CFD and 1D simulation of transient flow effect on air vessel
(BHR Group Limited, 2018)
The estimation of unsteady parameters in two-phase condition is crucial for the safety and reliability of the hydraulic systems. There are plenty of one-dimensional (1D) simulation tools for unsteady flow estimation being ...
