Numerical simulation of detonation wave propagation and quenching process in in-line crimped-ribbon flame arrester

Numerical Simulation to Investigate the Effect of Obstacle on Detonation Wave Propagation in a Pulse Detonation Engine Combustor

Pulse detonation technology can be a revolutionary approach for propulsion system since it offers significant fuel efficiency, higher thrust to weight ratio and low cost. Although the design concept of a pulse detonation engine is comparatively simple, but the development and stabilization of sustainable detonation wave front is difficult. Consequently pulse detonation engine technology is stil...

Numerical simulation of flood wave propagation due to failure of dam watersheds in fluent model

By numerical simulation of the phenomenon of failure of dams and the flow of their flow, it is possible to design more precisely the structures and their location. The purpose of this study was to investigate the wave propagation phenomenon due to the failure of the rocky mortar-watering dam in the Marivan sub-basin of Zarivar in two-dimensional and three-dimensional models using the Fluent mod...

Numerical Simulation of Quenching Process in Coal Gasification

This Master’s Thesis compares two computational fluid dynamics solvers: the commercial solver ANSYS CFX and the open source code OpenFOAM. Simple benchmark cases with compressible and incompressible flows are tested and compared. Thereafter the more complex process of quenching in coal gasification is simulated. This thesis work describes the simulation of a part of the coal gasification proces...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
