Electrical & Power ANSYS Fluent Training Package, 10 Practical Exercises for INTERMEDIATE Users

Power Engineering is one of the primary areas that has expanded within Electrical Engineering. It deals with the generation, transmission, and distribution of electric power. Power engineers also work on a diversity of power devices and on power conversion (the process of transforming power from one form into another, as in electromechanical or electrochemical processes).

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

Battery Thermal Management

Practical exercise number 1 simulates the cooling process of a battery (battery cooling) and thermal management by applying phase change material (PCM). Modeling is related to a lithium battery used in electrical vehicles. The battery is the main source of electricity and the essential part of the car’s electrical system. Problem number 7 simulates the thermal management of the battery using a Two-Phase Nanofluid.  This simulation is related to a Dual-Potential MSMD (multiscale multidomain) battery model. Generally, a battery can store electrical energy in chemical energy.

Air Conditioning of Transformer Room

Problem number 2 simulates the air conditioning inside a room where the transformers are located. Transformers are basically devices that can transfer electrical energy between two or more windings through electromagnetic induction, and as a result, a variable current in the primary winding of the transformer generates a variable magnetic field, which leads to voltage production in the secondary winding. These transformers are placed in a room due to safety issues, in which an optimal air conditioning system should be used where the transformers are stored.

MHD & EHD (Electrical & Power)

In project number 3, nanofluid flow in a three-dimensional solid aluminum channel in presence of an applied magnetic field is simulated to investigate the heat transfer. Fluid flow is steady and is simulated as one single-phase flow, however, the thermophysical properties of nanofluid are calculated using formulas. The surface average of the nanofluid’s temperature is equal to 293.2K and 304.175K at the inlet and outlet, respectively. Problem number 4 simulates a 2-D magnetic field’s effect on a nanofluid in a two-dimensional channel. Channel’s inner space is made of nanofluid, and its outer layer is made of aluminum. The nanofluid defined in the model is made of iron oxide called Fe3O4 and contains 2% nanoparticles. Issue number 9 concerns the simulation of airflow around a NACA 0015 airfoil applying magnetic force (MHD). This airfoil is a symmetrical airfoil that does not produce a lift force at zero attack angle, and we investigate the lift coefficient of this airfoil at different attack angles with and without magnetic (MHD) force. In this problem, we study the separation and the maximum angle of attack where the separation does not occur.

In project number 5, nanofluid flows in a bumpy channel in presence of an applied electrical field EHD(electrical potential). Fluid flow is steady and is simulated as one single-phase flow, however, the thermophysical properties of nanofluid are modified. The electrical characteristics of nanofluid alter the fluid mechanics’ behavior of flow which results in heat transfer increase.

Wind Turbine (Wind Farm)

Problem number 6 simulates wind turbines (HAWT) with the series arrangement in a wind farm. In this project, four wind turbines are designed in a row in a specific computational domain of ​​a large field called a wind farm (turbine farm). A wind turbine is a piece of equipment in the category of turbomachines that uses wind kinetic energy to generate electricity; In this way, a strong wind flow at high altitudes causes the turbine blades to rotate, and by rotating the central shaft of the turbine, an electric current is generated in the generator connected to the turbine body.

Fuel Cell

Practical exercise number 8 is going to simulate a fuel cell. The fuel cell used in this simulation is a type of polymer electrolyte membrane fuel cell (PEMFC). The model consists of two main cathode and anode segments, each of which has four layers, including a flow collector, a flow channel, a gas distribution area, and a catalytic section, and the space between the anode and cathode layers are filled by the polymer membrane.

Electrical Motor Impeller

Finally, in project number 10, the airflow passing over an electrical motor impeller is investigated. The airflow enters the computational domain at 80m/s, and the impeller rotates at 1000rpm. It should be noted that the MRF (frame motion) method has been activated to model the rotation of the impeller.
