Introduction

Electrical and Power Engineering is the discipline of engineering dealing with the practical uses of electricity in all of its forms, including electronics. Electronics engineering is a branch of electrical engineering concerned with using the electromagnetic spectrum and applying electronic devices such as integrated circuits and transistors. To accomplish specified functionality, electronic engineers develop and test circuits that leverage electrical components’ electromagnetic characteristics, including resistors, capacitors, inductors, diodes, and transistors.

Thermal management of electrical systems has been an essential topic of concentration in electronics research and development as electronic devices get smaller daily. Failure to provide adequate heat dissipation (cooling) in an electronic device, such as a computer or a smartphone, can result in a temporary or even permanent breakdown of the device due to the occurrence of extremely high temperatures in various parts, such as printed circuit boards (PCBs), central processing units (CPUs), or disk drives, which causes these components to malfunction. Thermal management must be given top importance in engineers’ electrical equipment design.

How to Improve Electrical and Power Engineering in CFD Simulations?

Electrical and electronic engineers frequently have to cope with possible overheating and thermal failure of the electronics or electrical equipment they develop. This can happen in severe locations, under strict conditions, or after long periods of continuous use in common ambient conditions. Fortunately, modern CFD technology permits electrical engineers to accurately predict the thermal performance of electronics and electrical equipment throughout the early design stages, giving engineers confidence that thermal failures in the field (and the associated warranty issues) are a thing of the past. Electronics CFD simulation tools will quickly and accurately account for all relevant physics, including the complexities of:

  • mixed convection effects (forced convection plus effects of natural convection)
  • buoyancy due to natural convection
  • conduction and heat dissipation within PCBs
  • boundary layer airflow and conjugate heat transfer on arbitrarily complex geometries and shapes
  • thermal radiation between all components and to the external environment. 

CFD on Increasing the Power of Vertical-Axis Turbines

Vertical-axis wind turbines (VAWTs) have recently attracted much attention for wind energy gathering offshore and in cities. This may be ascribed to its scalability, dependability, and minimal installation and maintenance costs for an offshore application. Their Omni-Directional capacity is their most significant benefit in areas with frequent changes in wind direction, such as urban surroundings. Computational Fluid Dynamics (CFD) has become a valuable and complementary tool to the designer and can be used for simulating, designing, and analyzing complex three-dimensional flows in turbomachinery. With the emergence and improvement of the commercial CFD software industry, computational modeling is being used much more by engineers with applications spanning an extensive engineering area.

Computational fluid dynamics are also used to load various actuators on the fins of various turbines to increase their efficiency with the lower input power that is pervasive nowadays.

 

 

 

 

 

CFD to Enhance IGBT Cooling

The IGBT is a solid-state switch that works by applying a voltage to a portion of a semiconductor to establish an electrical circuit. The IGBT is unusual because it eliminates the thyristor function, resulting in a more efficient device. Modern solar and wind turbine inverters, motor drives, and power systems use IGBTs.

Thermal control of IGBTs is a critical component of a well-designed power electronics system. Depending on its use case, switching state, and power input, IGBT modules can vary in temperature and create much heat. Even though IGBTs have aided us in making significant progress with renewable energy, inefficiencies related to heat loss and operating temperatures remain a design restriction.

CFD has achieved enormous popularity in modeling cooling efficacy within racks and aisles. Therefore it appears sensible to utilize it as a robust and dynamic tool to model data center settings. It performs a three-dimensional examination of hot and cold air circulation within the cold plate, identifying hot spots or regions that require further cooling or overly chilly parts. The customer may forecast the cooling power needed for his application using CFD.


Enhancement of Mining Farms Using CFD

Crypto farmers don’t have the budget, the margins, or the time to take the traditional route. They typically use whatever space is available a room in a house, a small office space, or an unused basement. Others utilize large warehouses where the hot air can dissipate quickly.

However, most of these spaces soon face challenges concerning overheating, rising electricity costs, and low efficiency.

The best way to solve these issues is through CFD simulation. It is possible to simulate room conditions to optimize the position of servers and determine how best to set up the airflow. As every crypto farm is unique, this has to be done individually. A simple simulation can rapidly determine the optimum amount of computing density for specific square footage. It calculates the facility’s temperature, air velocity, and hot and cold air interchange. A heat map highlights equipment hot spots that are likely to result in a server meltdown. This is accompanied by recommendations on modifying the room configuration to optimize crypto mining efficiency, performance, and cost.

 

 

This article covered a small number of CFD applications in improving Electrical and Power Engineering. The Power industry is full of applications for CFD, From battery cooling using PCM materials to the simulation of Electric Field Effect on Nanofluid Heat Transfer.

Fluid dynamics are fundamental to most facets of the Electrical sector. Although real prototypes are standard for later stages of development, design, and optimization during earlier stages can be significantly accelerated with CFD studies.

MR-CFD Services

The MR-CFD team conducted numerous outsourced simulation projects for industrial and research Electrical and Power Engineering applications. With several years of experience simulating various problems in various CFD fields using ANSYS Fluent software, the MR-CFD team is ready to offer extensive services of simulation configurations. For example, the simulation of Battery Cooling (Thermal Management) by PCM is freelanced and carried out to study the temperature control of a lithium battery used in vehicles.

The current challenge uses ANSYS Fluent software to model the cooling process (battery cooling) by employing phase change material (PCM). A lithium battery is used in cars, and modeling is connected. The battery is the car’s primary source of power and an important electrical system component. Chemical energy may be used to store electrical energy in the battery. When the battery is charged, the chemical energy is transferred to electrical power, and when the battery is discharged, the electrical energy is converted back to chemical energy. The automobile battery comprises six cells or components, each consisting of alternating plates between the cathode and anode plates.

CFD was used to design and equip an Electric Field Effect on Nanofluid Heat Transfer (EHD) in which the flow temperature is investigated. Nanofluid flows in a bumpy channel in the presence of an applied electrical potential applying ANSYS Fluent software.

As a result, a changing flow in the transformer’s primary winding produces an uneven magnetic field, which causes a voltage to be produced in the secondary winding. Due to safety concerns, these transformers are housed in a room where an adequate air conditioning system should be employed. These transformers are heat sources that influence the temperature of the surrounding air.

The ANSYS Fluent Software can simulate the ventilation of the transformer room. The following study is simulated Transformer Room Ventilation, and its results show the same air pressure, velocity, or temperature at each desired point.
