Gas and Petrochemical CFD Training Package for Beginners, 10 Practical Exercises

Description

Gas and Petrochemical ANSYS Fluent Training Package, 10 Practical Exercises for BEGINNER Users

A petrochemical engineer’s main duty is to expand roads to break down oil and petroleum, then use the foundation components to extend everyday products like plastic, rubber, and synthetic fibers. Petroleum and Gas Engineering is a field of engineering interested in the works related to the exploration, extraction, production, and processing of hydrocarbon, which can be either crude oil or natural gas. Instances of petrochemical fuels are liquefied petroleum gas (LPG), kerosene, diesel, gasoline, and jet fuels. Attend that a refinery produces other valuable products such as waxes, asphalts, plastic materials, lubricants, and greases.

There are lots of Gas and Petrochemical engineering projects that are simulated by ANSYS Fluent software using CFD methods. This CFD training package includes 10 practical exercises related to the Gas & Petrochemical Engineering field and industrial devices at the BEGINNER level.

The 1st Practical Exercise simulates the effects of the oil tank detonation process in an urban area and the pollutant emission by ANSYS Fluent software. In fact, in areas where there are oil reservoirs, one of the potential dangers is an explosion. The explosion of these oil tanks can lead to the release of many pollutants such as carbon dioxide into the environment.

One of the most widely used multiphase analyses is the Discrete Phase Model (DPM) analysis, which is widely used to investigate the effect of fine matter mixtures in the main fluid flow on its conditions. Considering the various cases of fluid streams with particles that are seen in the industry as well as nature, the study and analysis of such flows can be a great help in understanding such issues. In the 2nd Practical Exercise, the airflow containing micro-particles inside an elbow is simulated by ANSYS Fluent software.

The 3rd Practical Exercise simulates the water discharge of a rectangular tank under the influence of gravity by Ansys Fluent software. The VOF model has been used to simulate and solve the two-phase flow field equations. The computational domain consists of three tanks that are connected by pipes.

In the 4th Practical Exercise, numerical simulation of Oil Jet Impact on the Water Tank has been done using Ansys Fluent software. the system consists of three different fluids, including air as the primary fluid and one secondary fluid is liquid water, and the last is oil. The Eulerian multiphase model has been used.

The 5th Practical Exercise stimulates the Tank Filling (2-Phase) by Ansys Fluent software. In this project, we simulate Tank charge/filling (2-phase) between two reservoirs with fluid air and water and the same height of tanks. The goal of many operations in the Petrochemical industry is to separate the components of a solution or mixture from each other or to obtain a pure substance from a combination of two or more components.

The 6th Practical Exercise stimulates the Tank Filling (3-Phase) by Ansys Fluent software. In this Tank Filling simulation, using the VOF (volume of fluid) method, the interaction of three phases, including water, alcohol, and air was investigated. For this purpose, the effect of shear forces on the boundary between the phases was applied by applying surface stresses between the two phases.

In the 7th Practical Exercise, a two-phase flow of vapor and liquid ammonia in a two-phase Ejector has been simulated by ANSYS Fluent software. The realizable k-epsilon model is used for flow analysis. The VOF multiphase model for two phases of liquid ammonia and vapor ammonia has been used to investigate the phase interactions.

In the 8th Practical Exercise, steady airflow mixing with fuel is investigated by ANSYS Fluent in a 3-outlet Manifold where only one outlet is effective and the other 2 outlets are blocked. There are two inlets that provide air and fuel flow into the domain. Air and fuel flow rates are equal to 0.2335 and 0.0374 kg/s.

EROSION in Pipelines

Fluid impurity is not a problem in a straight-ahead pipeline. But when the fluid redirects, these impurities cannot redirect with the fluid. The 9th Practical Exercise stimulates the Erosion in a 90-degree knee by Ansys Fluent software. The 10th Practical Exercise simulation is modeling Erosion in the bent pipe by a Two-way DPM Erosion Model to see the erosion rate in the pipe using ANSYS Fluent software. The working fluid is water liquid, and sand particles are DPM injections. Particles are inert and with no initial velocity.
