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.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

insulation space.
• Air pockets should not remain against the building board,
the air or moisture insulation or the timber studs.
• The structures must be made air tight.

tapes and are tightened with battens.
• The joints of sheathing boards are fitted against the frame
structures and, if needed, strengthened with exterior
battens.

16. Insulation and structure of a ventilated
'crawling space' in a low energy house 1/2
1. The sheathing in the 'crawling space' should always be
very moisture resistant. The sheathing materials should
not be sensitive to mould. The heat resistance of the
sheathing should be always at least 0.4 m2 K/W.
2. The moisture transfer between dry ashlar walling and heat
insulation or sheathing board should be prevented.
3. Heat insulation covering the entire ground raises the
temperature of the ‘crawling space’ which reduces the
relative humidity and the favourable conditions for mould
development. Organic building materials or waste should
not be left on the ground.
4. Heat insulation on the underside of the bearing structures
reduces the moisture movements of structures and
protects the timber structures from mould forming.
5. Also ventilation of the base floor significantly affects the
conditions. The recommended ventilation rate is 0.5-1 1/h.
6. The need for inner frost protection increases because the
heat loss through the base floor decreases.
7. The order of work should be planned beforehand so the
structures can be sealed properly. The base floor must be
made totally airtight.

17. Insulation and structures in the roof
space of low energy houses
1. The heavy load of heat insulation and the
need for bearing must be considered. The
bearing can be improved by making the
battening denser or supporting the heat
insulation with sheets.
2. The temperature in the roof space will
decrease and the relative humidity will
increase. Proper conditions for the
development of mould will increase.
3. The heat insulating underlay raises the
temperature in the roof space and reduces
the development of mould.
4. It is recommended to install the heat
insulating sheathing board to the exterior
surface of the timber frame. Heat resistance
of the board min 0,4 m²K/W.
5. As the length of eaves increases so the bend
due to snow load increases. This must be
considered especially with brick facing.

18. Consider: What are the most important
effects on moisture control when the
insulation thickness is increased?
• Heat loss decreases so structures cool down.
• Cooling down slows the drying of the building
envelope.
• The risk of moisture damage increases.
• Tightness of the vapour barrier, air tightness and
ventilation will become paramount.
• Weather condition protection will become more
important.
19. Remember
• Thermal insulation should be installed tightly against the frame
• Soft thermal insulation under light pressure.
• Hard thermal insulation is foamed approx. 5-10 cm; the gap for foam
should be min 10 mm.
• Tongue and groove joints are installed in the foamed butt joint.
• Vapour-proof foil should not break and is installed to allow
movement of the frame.
• The joints of vapour-proof foil should be made as pressure joints if
possible.
• In the joints of wind shield board, battening is recommended
(at least in the corners).
• The structures should be tight for decades.
• Taping alone is not enough because tapes perish and do not
withstand the movements resulting from heat, moisture and snow
load.
20. The good practices and principles required for the energy efficient building have been
included in the teaching material. The writers are not responsible for their suitability to
individual building projects as such. The individual building projects have to be made
according to the building design of the targets in question.
