Computational algorithm was developed based on the well-known ANSYS Fluent  software package for studying unsteady wave outflow of a saturated liquid from high-pressure pipelines during emergency depressurization. The processes liquid, boiling as result depressurization vessels, have been investigated. system equations conservation mass, momentum, and energy in two-dimensional coord...

Application structural analy...

nowadays, tube bonding in vehicles structure is noticeably considered by many researches. in this paper, local tube compression process by a rubber ring has been studied. firstly, simulation of the process was performed by fem. then, experimental test has been carried out to validate the numerical results. numerical and experimental results were compared showing a good agreement. in the second ...

University Hospital of Clermont-Ferrand requested decision-making software in order to help the practitioners to choose a strategy and to make choices. First we have to understand and identify the system with accuracy and choose the best tools to develop this software. Therefore, we need to select a language (BPMN) and a methodology (ASDI) able to model the processes of the system following cho...

a linear low density polyethylene (lldpe) production process, including two- fuidized bed reactors in series (fbrs) and other process equipment, was completely simulated by aspen polymer plus software. fluidized bed reactors were considered as continuous stirred tank reactors (cstr consisted of polymer and gas phases). poly-srk and nrtl-rk equations of state were used to describe polymer and no...
