Electrical & Power ANSYS Fluent Training Package, 10 Practical Exercises for BEGINNER 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 BEGINNER level.

Heat Sink & Heat Source

The 1st Practical exercise deals with the simulation of heat sink cooling. In the present model, a surface as a heat source with a heat flux equivalent to 600,000 W.m-2 is located at the bottom of the model, which is responsible for continuous heat generation. On this surface, a solid object with several rows of parallel grooves is located to perform the cooling process of high-temperature surfaces. In the 2nd practical exercise, the cooling of an IGBT heat sink is simulated by ANSYS Fluent software. The heat sink is in contact with a heat source (with a heat flux of 14583 W/m²) on one side and the air flows on the other side with a mass flow of 0.25Kg/s. The airflow is responsible for cooling the heat sink.

In the 3rd practical exercise, fluid flows in a Microchannel Heat Source which is surrounded by a copper solid channel, having a heat flux wall is simulated by ANSYS Fluent software. Electronic devices which have millimeter dimensions are in constant need of cooling due to their high heat generation rate. Macro heat exchangers and radiators are not efficient enough to cool down these devices which generate heat at megawatts per meter square. The 4th practical exercise simulates the heat transfer of water flow inside a microchannel heat sink using ANSYS Fluent software. One of the serious problems in designing electronic equipment due to its small structure is eliminating the generated heat. This simulation investigates the thermal performance of a cylindrical microchannel heat sink for electronic equipment cooling.

So in the 5th practical exercise, the fluid flow and heat transfer inside a heat sink with the porous medium is simulated by ANSYS Fluent software. This porous medium is in contact with a heat source and the whole setup acts as a heat sink. The energy model is activated and the RNG  k-epsilon model with the use of standard wall function is exploited for fluid flow analysis.

Generator, Heller, and Solar Chimney

In the 6th practical exercise, the airflow inside a dry cooling tower (HELLER) is simulated and analyzed by ANSYS Fluent. A dry cooling tower is used as a means of indirect heat transfer between the working fluid (water) and the coolant (air). In a thermal plant, the working fluid (water) exits the condensers and then is pumped into a ring of heat exchangers. In the 7th practical exercise, the Transient simulation of the Heller cooling tower is investigated by ANSYS Fluent software. Heller cooling tower is an indirect heat exchanging mechanism in which airflow over the water stream and heat exchange process density decreases, and an upward flow is generated. In the present work, an ideal gas model is used for air density modeling.

In the 8th practical exercise, a Solar Chimney is simulated by ANSYS Fluent software. One way to utilize solar energy is the solar chimney. The basis for a solar chimney is the difference in density and pressure difference due to the increase in temperature inside the solar collectors, which acts as a force. Solar energy is one of the cleanest and most accessible sources of electricity on earth, especially in areas with high annual solar radiation applied in power plants. There is a transparent roof that is capable of absorbing solar radiation energy. On the other hand, the air entering the system from the sides of this roof collects in the space between the roof and the ground.

As the last training for the INTERMEDIATE users, The 9th practical exercise simulates the airflow around several Generators and the effect of a set of fans on the HAVC system, using ANSYS Fluent software. Generators are generally mechanical devices that can convert mechanical energy into AC or DC electrical energy. This process of generating electricity is done by changing the magnetic field of a conductor.

MHD (Electrical)

The 10th practical exercise simulates a fluid flow with electrical conductivity properties in a simple square chamber by ANSYS Fluent software. The MHD model was used to model this project. Magnetohydrodynamics (MHD) is a science that studies the magnetic properties of electrically conductive fluids. In fact, the MHD deals with the interaction between magnetic particles within a fluid stream and the magnetic field.
