An autonomous underwater vehicle (AUV) is a robot which travels underwater without requiring input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications AUVs are more often referred to simply as unmanned undersea vehicles (UUVs).

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.

2. What is SUBMARINE
A submarine is a watercraft capable of independent operation underwater,
usually built for warfare and armed with torpedoes or guided missiles. The
term most commonly refers to a large, crewed vessel
Unlike a ship, a submarine can control its buoyancy, thus allowing it to sink
and surface at will.
4. Pressure hull
Has inner and outer hulls
Ballast tanks are in between two hulls
Withstand high pressure
Shock loads
Longitudinal compressive stresses
Made from tough steel or titanium
5. Ballast tanks
There control buoyancy
When Diving they are filled with water and air in it is
vented
When submerging Compressed air is filled into tank and
air is flooded out
To keep the submarine at any desired depth Equal
proportions of water and air is maintained in the tank
7. Diving
As the submarine dives, the ballast tanks
are flooded with water and the air in the
ballast tanks is vented from the submarine
until its overall density is greater than the
surrounding water and the submarine
begins to sink (negative buoyancy).
In addition, the submarine has movable
sets of short "wings" called hydroplanes on
the stern (back) that help to control the
angle of the dive.
8. Surfacing
When the submarine is on the surface, the ballast tanks
are filled with air and the submarine's overall density is
less than that of the surrounding water (positive
buoyancy)
A supply of compressed air is maintained aboard the
submarine in air flasks for life support and for use with
the ballast tanks.
To keep the submarine level at any set depth, the
submarine maintains a balance of air and water in the
trim tanks so that its overall density is equal to the
surrounding water (neutral buoyancy).
9. Steering
The submarine can steer in the water by using the tail rudder to turn
starboard (right) or port (left) and the hydroplanes to control the fore-
aft angle of the submarine.
In addition, some submarines are equipped with a retractable
secondary propulsion motor that can swivel 360 degrees.
11. Diesel – electric engines
The diesel engine operates normally when the sub is near the surface but it doesn't drive the
sub's propellers directly. Instead, it powers an electricity generator that charges up huge
batteries.
These drive an electric motor that, in turn, powers the propellers. Once the diesel engine has
fully charged the batteries, the sub can switch off its engine and go underwater, where it
relies entirely on battery power.
Early military submarines used breathing tubes called snorkels to feed air to their engines
from the air above the sea, but that meant they had to operate very near the surface where
they were vulnerable to attack from airplanes.
12. Nuclear engines
Most large military submarines are now nuclear-powered.
Like nuclear power plants, they have small nuclear reactors and, since they need no air to
operate.
they can generate power to drive the electric motors and propellers whether they are on the
surface or deep underwater.
14. Life Support systems
Maintaining the air quality
Maintaining a fresh water supply
Maintaining temperature
15. Maintaining the Air Quality
The air we breathe is made up of four gases: nitrogen, oxygen, argon,
and carbon dioxide.
Oxygen is produced by electrolysis.
Machines called scrubbers use soda lime to trap carbon dioxide.
Dehumidifiers remove the moisture from exhaled air.
16. Most ships have special equipment that can remove the salts from seawater to turn
it into fresh drinking water. This process is called Distillation.
Some submarines can produce up to 40,000 gallons of fresh water per day.
It is used for everything from cooling electronic equipment to cooking and
showering
MANTAINING OF FRESH WATER SUPPLY
17. Maintaining Temperature
The metal of the submarine conducts internal heat to the surrounding water.
So, submarines must be Electrically heated to maintain a comfortable
temperature for the crew.
The electrical power for the heaters comes from the nuclear reactor, diesel
engine, or batteries (emergency).
18. Navigation
Submarines are equipped with navigational charts and sophisticated
navigational equipment.
When on the surface, a sophisticated global positioning system (GPS)
accurately determines latitude and longitude, but this system cannot work
when the submarine is submerged.
Underwater, the submarine uses inertial guidance systems (electric,
mechanical) that keep track of the ship's motion from a fixed starting point
by using gyroscopes.
19. Periscope
Seeing tubes that can be pushed up through the Tower.
Useful when the submarine is near the surface or on the surface.
Useless under water.
20. Sonar
To locate a target, a submarine uses active and passive SONAR (Sound
Navigation And Ranging).
Two types
Active sonar
Passive sonar
21. Torpedo
The modern torpedo is a self-propelled weapon with
an explosive warhead, launched above or below the
water surface, propelled underwater towards a target,
and designed to detonate either on contact with its
target or in proximity to it.
