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.

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.

CONSTRUCTED LANDSCAPE [ARC30203]
Prerequisite: None
Lecturer: Shazreene Nurjanna Samsudin, Noorul Iffa Mohd Nayan
Project 3 (Final)
Residential Landscape Project
40% Individual
Submission: 31st July 2015, Friday (Week 16)
Introduction
Projects in landscape architecture progress through stages, from the very first contact with the client
and awareness of the site, through to the realization, construction and maturation of the finished design.
It is important to remember that the design process, unlike a timeline, is often completely non-linear.
The phrase “back to the drawing board” refers to the continual process of testing and retesting that is
characteristic of the architectures.
In the planning of a residence, there are not only the space is matters but also to integrate the natural
site component with its landscape environs. Since the area to be developed is small scale, the design
will take into account all positive qualities of the site – the ground forms, cover, exposures, views, and
all other natural or architectural features – and bring them into harmony.
“The earth is our home and the ways of nature our paths to understanding”.
[Simonds, J. O.]
Objectives of Project
The objectives of this project:
To acquire knowledge about design process, planning and development of project.
To proffer exposure of small scale landscape project to the students.
To familiarize students about the design stages and how to visualize their ideas onto
presentation boards.
Learning Outcomes of this Project
On successful completion of this subject, students will be able to demonstrate the following:
1. A design process involved in landscape project development and the representation of ideas
for every stage taken.
2. Understanding on landscape design components and how it works and have been applied into
the field.
2. 2
Tasks - Methodology
This is a continuous assignment of Project 2 and an individual project. From the same site that you
were doing for previous Project 2, you are required to design the landscape for the residence/house.
You have to imagine that you are going to present the landscape proposal to the client (who is the
house owner) by preparing ALL drawings needed for every development stages. The development
stages shall include as following;
A. PROJECT DESCRIPTION
A short paragraph of your design statement which explaining about the ideas, rationale of the
design and the concept of the design. The narration should briefly describe, constructive and
informative.
*note: It is advisable to complete at the end of the process
B. CONCEPTUAL DIAGRAM
From the site synthesis (refer to previous individual component of project 2), develop a bubble
diagram. Bubble diagram is used as a means to show what spaces and activities that you want
to propose at the site. Subsequently, you need to come out with a conceptual diagram.
Conceptual diagram is a breakdown (more detailed) of your synthesis (design solutions) and
bubble diagram which related to the site.
C. SCHEMATIC PLAN
From the conceptual plan, you need to develop a schematic plan. It is also known as
preliminary master plan. In schematic plan, you are to compose all of elements that you intend
to put into the design. It should have form composition, shape and pattern of the design
elements. You may provide sketches/illustrations (sections/elevations) to better represent your
ideas.
D. MASTER PLAN
After the schematic plan has been approved by your tutor, you should produce a master plan
set of drawings. The set of drawings include;
- Master Plan
- Elevation & Section
- Hardscape Palette
- Softscape Palette
E. COST ESTIMATION & MAINTENANCE PLAN
A brief cost estimation or budget allocation of the landscape project that you proposed.. The
cost estimation is regarded to be as preliminary bill of quantities (BQ). Additionally, you are
also to include a brief maintenance plan of the project.
(These two topics will be taught by guest lecturer (QS Lecturer) in Week 14).
**Note:
A self-independent study is required on graphic communication particularly on architectural lettering,
sketching,colouring & presentation layout. Do save images from internet or scan from books for ideas
collection and inspirations.
