Jets

Project number 1 investigates the jet’s impact on resident water. The system consists of two different fluids, including water as the primary fluid and one secondary fluid as Air. The Eulerian multiphase model has been used. The jet air is entering the domain with a speed of 24 m/s with gravity considered as -9.81 m/s-2 on the y-axis.

Project number 2 simulates colliding of two water jets. The system consists of two different fluids, including Air as the primary fluid and one secondary fluid liquid water. The Eulerian multiphase model has been used. The water is entering the domain with a speed of 15m/s with gravity considered as -9.81 m/s-2 on the y-axis.

Project number 3 simulates the firehose. The system consists of two different fluids, including Air as the primary fluid and one secondary fluid water. The Eulerian multiphase model has been used. The water is entering the domain with a speed of 9 m/s with gravity considered as -9.81 m/s-2 on the y-axis.

In project number 4, a numerical simulation of the Oil Jet Impact on the Water Tank has been done. The system consists of three different fluids, including Air as the primary fluid and one secondary fluid liquid water, and the last is oil. The Eulerian multiphase model has been used. The oil is entering the domain with a speed of 8m/s with gravity considered as -9.81 m/s-2 on the y-axis.

Slug Flow

The goal of project number 5 is to simulate slug flow in a pipe. There is a multiphase-flow regime in tubes in which most of the lighter fluid is contained in large bubbles dispersed within and pushing along the heavier fluid. There are tiny bubbles within the liquid, but many merge to form large bubbles until they span much of the pipe. In gas-liquid mixtures, slug flow is similar to plug flow, but the bubbles are generally more giant and faster.

Catalytic Reactor (EULERIAN Multi-phase Model)

Project number 6 simulates the flow inside a catalytic reactor. In the internal structure of this reactor, compressed Air is mixed with the fuel spray into the reactor and the catalyst material to cause the reaction to occur. For this multi-phase flow, three materials are defined; Air with a density of 1.225 kg.m-3 is introduced as the primary phase, fuel with a density of 10 kg.m-3, and catalytic material with a density of 700 kg.m-3 is introduced as secondary phases.

Vortex Separator

Project number 7 simulates a two-phase flow inside a hydrodynamic vortex separator. These hydrodynamic vortex separators (HDVS), can separate soluble particles in a fluid from the base fluid. In the present simulation, water flow is defined as a base fluid with a density of 1000 kg.m-3 and a viscosity of 0.001 kg.m-1.s-.

Borehole

Project number 8 simulates borehole water flow. These boreholes can be drilled vertically, horizontally, or sloping and have an essential role in sampling soil materials, checking surface layers, sending equipment and tools, studying the soil condition of the area, etc.  Since this project simulates a mixture of water flow and soil grains, a multi-phase flow must be defined. Therefore, the Eulerian multi-phase model determines the liquid-solid two-phase flow.

Non-Newtonian Fluid (EULERIAN Multi-phase Model)

Non-Newtonian fluid is a fluid that does not follow Newton’s law of viscosity, i.e., constant viscosity independent of stress. In non-Newtonian fluids, viscosity can change when under force to either more liquid or more solid. In project number 9, the two-phase flow of a non-Newtonian fluid consisting of materials of Drilling and CMC between two eccentric cylinders has been simulated. The Eulerian multiphase model for two phases of Drilling and CMC has been used to investigate the phase interactions of the non-Newtonian fluid.

Cascade

The goal of project number 10 is to simulate a cascade with an interrupted water inlet. The Eulerian multiphase model has been used. The water is entering the domain with the speed of 0.3 m/s with gravity considered as -9.81 m/s-2 on the y-axis.
