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.

3. 1. Concept of inheritance:
Inheritance is one of the feature of Object Oriented Programming
System(OOPs), it allows the child class to acquire the properties (the data
members) and functionality (the member functions) of parent class.
Inheritance is a process in which one object acquires all the properties and
behaviors of its parent object automatically.
The technique of deriving a new class from an old one is called inheritance.
Inheritance is a mechanism in which one class acquires the property of
another class.
For example, a child inherits the traits of his/her parents.
It allows user to create a new class (derived class, subclass, child class) from
an existing class(base class, super class, parent class).
The derived class inherits all the features from the base class and can have additional
features of its own.
Dr.Mirza Waseem Hussain 3
4. 2. Advantages of inheritance:
a) Reusability
When child class inherits the properties and functionality of parent class, we need not to
write the same code again in child class.
b) Readability
It’s easier to reuse the code, makes us write the less code and the code becomes much
more readable.
3. General Syntax of inheritance:
class base_class1{ //Member functions of base class };
class base_classN{ //Member functions of base class };
derived_class:: visibility_mode base_class1, visibility_mode base_class2, ….,
visibility_mode base_classN { ……. //Member functions of derived
class.
};
Dr.Mirza Waseem Hussain 4
Note: A class that inherits another class is known
as child class, it is also known as derived class or
subclass.
Note: The class that is being inherited by other
class is known as parent class, super class or base
class.
5. 4. Inheritance Access specifier/ Visibilty modes:
Access Specifiers defines the visibility of the Property /Fields/ Variable/ Methods of a
class.
Access modifiers (or access specifiers) are keywords in object-oriented languages that
set the accessibility of classes, methods, and other members.
There are three types of Access specifiers in C++ to define the visibility modes of
inheritance.
• Private.
• Public .
• Protected.
A. Public mode:
If we derive a sub class from a public base class. Then the public member of the base
class will become public in the derived class and protected members of the base class
will become protected in derived class.
syntax:
class derive_class::public base_class{ … //Member functions of derived class
};
Dr.Mirza Waseem Hussain 5
6. B. Protected:
If we derive a sub class from a Protected base class. Then both public member
and protected members of the base class will become protected in derived class.
syntax:
class derive_class::protected base_class{ … //Member functions of derived class
};
C. Private:
If we derive a sub class from a Private base class. Then both public member and
protected members of the base class will become Private in derived class.
syntax:
class derive_class::private base_class{ … //Member functions of derived class
};
Dr.Mirza Waseem Hussain 6
Note:The private members in the base class cannot be directly accessed in the derived class, while
public and protected members can be directly accessed.
7. Table 1 summarizes the visibility modes of inheritance.
