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.

10. GRAVITY DAM
• Gravity Dams resist the horizontal thrust of water
entirely by their own weight
• Concrete Gravity Dams are typically used to
block streams through narrow gorges
• Concrete gravity dams tend to use a large
amount concrete which make these expensive
• Generally the base of a concrete gravity dam is
equal to 0.7 times the height of the dam
12. ARCH DAM
• An Arched Dam is a curved Dam, dependent
upon arch action for its strength
• Arch Dams are thinner and therefore require
less material than any other type of dam
• Arch dams are good for sites that are narrow
and have strong abutments
14. BUTTRESS DAM
• Buttress Dams are dams in which the face is
held up by a series of supports
• Buttress Dams can take many forms , the face
may be flat or curved
• Buttress Dams are made of concrete and may
be reinforced with steel bars. The buttress
may be hollow or solid

37. OBJECTIVES
Calculate seismic risk factor for different
project structures to be constructed.
Calculate the maximum credible
earthquake posing great hazard to dam.
Investigate the seismicity induced by
filling of Tarbela reservoir.
Gather data for exchange with different
international organizations.
Make an attempt for the prediction of
earthquake
38. RESERVOIR INDUCED SEISMICITY
Reorganization in Seismicity is generally
confined up to shallow depths i.e. 20 km.
and limited to a radial distance of about
50 km.
Increased seismic activity associated with
rapid filling/depleting is a direct effect of
loading/unloading through either shear
stress or increased pore pressure. These
induced events are mostly of low
magnitude. However, after quiescence in
Seismicity, felt events may occur with
magnitudes up to 5.5.

Earthquake felt around the Dams may be potentially damaging depending
on their intensity and duration of shaking. a tremor with intensities of vi
or higher on modified Mercalli (M.M) Intensity scale will cause visible
damage. therefore, emergency drill must be called for.
OBJECTIVES:
To take immediate actions to assess the damages.
To take necessary actions to lessen or prevent the consequences of
damages around the Dams and down stream areas.
To evaluate the remedial actions for restoring of functional adequacy of
damaged project features as soon as possible.
