Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

2. ventilation
• The process of supply of fresh air and replenish
oxygen supply to occupied and unoccupied space
within building and other inhabited structures is called
ventilation.
3. Ventilation is necessary to:
1. Replenish the oxygen supply
2. Dilute carbon dioxide
3. Dilute odour, process emission
4. Provide air movement
5. Reduce humidity
6. Prevent the build up of potentially explosive vapour mixtures
Requirement of good ventilation:
1. It should admit sufficient quantity of fresh air and remove the requisite
contaminated air.
2. It should admit clean and humid air.
3. It should continuously change the air inside the room.
4. It should properly control the velocity &quantity of air inside the space.
5. The system should also control the temperature of the admitted air.
4. SYSTEM OF VENTILATION
1.Natural ventilation
2.Mechanical ventilation
1. Natural ventilation
It relies on the pressure of opening in the ventilated structure. In natural
ventilation the effect of two mechanisms that cause air exchange through
these opening based on temperature and pressure effects are very
important.
Change in the pressure over the surface of the building due to the effect
of the building and surrounding structures on the local air flow patterns,
leads to both driving and suction effects. The temperature difference
between the inside and outside of the building leads to density variations
and the stack effect.
Doors and window near the floor level, admits fresh air and ventilatiors
near the ceiling take out the vitiated air from a room. Fan lights of 30 cm
6. In case of sloped roof, ridge ventilations may be provided
to remove vitiated air from large hall as shown in fig.
7. 2. Mechanical ventilation (Artificial ventilation)
Mechanical ventilation technique is suitable for energy controlled
buildings, those where sealing the building become necessary
for other reasons, e.g. acoustic pollution and buildings
incorporating processes generating contaminants.
Mechanical ventilation may be classified as,
1. vaccume system
2. propulsion system
3. air conditioning system
1. vaccume system
in this system exhaust fans or blowers are installed near the
ceiling to extract used up air from inside and though it outside.
Due to exhausting of warm air from the room will reduce causing
flow of fresh air inside the room.
8. 2. Propulsion system
In this system fresh air is forced from outside by force fans and
vantiated air is thrown out by itself or by outlet exhaust fan. E.g.
air cooler at a window
3. air conditioning system
It is the process of controlling temperature, humidity and
distribution of air inside the building/room, with simultaneous
removal of dirt, bacteria and toxic matter from the inside air.
In polluted urban environment, natural ventilation and ordinary
mechanical ventilation system are not suitable. In such situations,
air- conditioning is the most suitable system.
9. AIR CONDITIONING SYSTEMS
A brode classification of the air conditioning system is given below.
1) Based on major function
- comfort air condition
- Industrial air condition
2) Based on season
- winter air condition
- summer air condition
- year round air condition
3) Based on equipment arrangement
- unitary system
- central system
10. Comfort air conditioning:- This system, aims at creating atmospheric
conditions conductive to human health, comfort and efficiency. Air
conditioning systems in homes, offices, store, restaurants, theatres,
hospitals and schools are of this type.
Industrial air conditioning:- The purpose of this system is to control
atmospheric conditions primarily for the proper conduct of research and
manufacturing operations. This system is used in laboratories, printing,
textile, steel manufacturing, pharamaceutical, photographic productions,
animal farms, etc.
Winter air Conditioning:- This system are designed and installed indoor
atmospheric conditions for winter comfort and involve heating of the air and
humidification. Heating is accomplished by furnaces or boilers fired with gas,
oil or coal.
The cycle of operation consists of:
1. air cleaning
2. air heating
11.
12. Summer air conditioning: this system are designed for
controlling atmospheric conditions for summer comfort and
involve coolling of the air and dehumidification.
The cycle of operation consists of:
1. Air cleaning
2. air cooling
3. dehumidification
4. air distribution/circulation
13.
14. Year round air conditioning: These systems comprise heating
and cooling equipment with automatic controls to produce
condition for all time of year.
Unitary system: All the components of the unitary air
conditioning system are assembled in the factory itself. These
assembled units are usually installed in or immediately adjacent
to a zone or space to be conditioned.
Advantage of unitary system
1.the installation and assembly labour charges are less.
2. Zoning or extensive duct work is eliminated.
3. failure of the unit puts off conditioning in only one room where
the failure of the central plant offsets all the rooms to be served
4. Individual room temperature control is a specific feature of this
system.
