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.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

2. Introduction
• JavaScript is a front-end scripting language
developed by Netscape for dynamic content
– Lightweight, but with limited capabilities
– Can be used as object-oriented language
• Client-side technology
– Embedded in your HTML page
– Interpreted by the Web browser
• Simple and flexible
02/02/19 2
3. • HTML to define the content of web pages
• CSS to specify the layout of web pages
• JavaScript to program the dynamic behavior
of web pages
02/02/19 3
4. Using JavaScript Code
• The JavaScript code can be placed in:
– <script> tag in the head </script>
– <script> tag in the body </script>
– External files, linked via <script> tag in the head
• Files usually have .js extension
4
<script src="scripts.js" type="text/javscript"><script src="scripts.js" type="text/javscript">
</script></script>
7. <html><html>

9. <script type = "text/JavaScript" language="JavaScript">
var a = "These sentence";
var italics_a = a.italics();
var b = "will continue over";
var upper_b = b.toUpperCase();
var c = "three variables";
var red_c = c.fontcolor("red");
var sentence = a+b+c;
var sentence_change = italics_a+upper_b+red_c;
document.write(sentence);
document.write("<br>");
document.write(sentence_change);
</script>
10. Standard Popup Boxes
• Alert box with text and [OK] button
– Just a message shown in a dialog box:
• Confirmation box
– Contains text, [OK] button and [Cancel] button:
• Prompt box
– Contains text, input field with default value:
10
alert("Some text here");alert("Some text here");
confirm("Are you sure?");confirm("Are you sure?");
prompt ("enter amount", 10);prompt ("enter amount", 10);
11. Alert Dialog Box
<html> <head>
<script type="text/javascript">
function Warn() {
alert ("This is a warning message!");
document.write ("This is a warning message!");
}
</script>
</head>
<body>
<p>Click the following button to see the result: </p>
<form> <input type="button" value="Click Me" onclick="Warn();" />
</form>
</body></html>

<body>
<p>Click the following button to see the result: </p>
<form>
<input type="button" value="Click Me" onclick="getValue();" />
</form>
</body></html>
14. JavaScript Syntax
• The JavaScript syntax is similar to Java
– Operators (+, *, =, !=, &&, ++, …)
– Variables (typeless)
– Conditional statements (if, else)
– Loops (for, while)
– Arrays (my_array[]) and associative arrays
(my_array['abc'])
– Functions (can return value)
14
15. Data Types
• JavaScript data types:
– Numbers (integer, floating-point)
– Boolean (true / false)
• String type – string of characters
• Arrays
• Associative arrays (hash tables)
15
var myName = "You can use both single or doublevar myName = "You can use both single or double
quotes for strings";quotes for strings";
var my_array = [1, 5.3, "aaa"];var my_array = [1, 5.3, "aaa"];
var my_hash = {a:2, b:3, c:"text"};var my_hash = {a:2, b:3, c:"text"};
16. Everything is Object• Every variable can be considered as object
– For example strings and arrays have member
functions:
16
var test = "some string";var test = "some string";
alert(test[7]); // shows letter 'r'alert(test[7]); // shows letter 'r'
alert(test.charAt(5)); // shows letter 's'alert(test.charAt(5)); // shows letter 's'
alert("test".charAt(1)); //shows letter 'e'alert("test".charAt(1)); //shows letter 'e'
alert("test".substring(1,3)); //shows 'esalert("test".substring(1,3)); //shows 'es''
var arr = [1,3,4];var arr = [1,3,4];
alert (arr.length); // shows 3alert (arr.length); // shows 3
arr.push(7); // appends 7 to end of arrayarr.push(7); // appends 7 to end of array
alert (arr[3]); // shows 7alert (arr[3]); // shows 7
