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.

Laundry management system project report.pdfKamal Acharya
Laundry firms currently use a manual system for the management and maintenance of critical information. The current system requires numerous paper forms, with data stores spread throughout the laundry management infrastructure. Often information is incomplete or does not follow management standards. Records are often lost in transit during computation requiring a comprehensive auditing process to ensure that no vital information is lost. Multiple copies of the same information exist in the laundry firm data and may lead to inconsistencies in data in various data stores.
A significant part of the operation of any laundry firm involves the acquisition, management and timely retrieval of great volumes of information. This information typically involves; customer personal information and clothing records history, user information, price of delivery and received date, users scheduling as regards customers details and dealings in service rendered, also our products package waiting list. All of this information must be managed in an efficient and cost wise fashion so that the organization resources may be effectively utilized.
We present the design and implementation of a laundry database management system (LBMS) used in a laundry establishment. Laundry firms are usually faced with difficulties in keeping detailed records of customers clothing; this little problem as seen to most laundry firms is highly discouraging as customers are filled with disappointments, arising from issues such as customer clothes mix-ups and untimely retrieval of clothes. The aim of this application is to determine the number of clothes collected, in relation to their owners, as this also helps the users fix a date for the collection of their clothes. Also customer’s information is secured, as a specific id is allocated per registration to avoid contrasting information.

3. What is MCDM process?
Multiple-criteria decision-making (MCDM) or multiple-criteria decision analysis (MCDA) is a sub-
discipline of operations research that explicitly evaluates multiple conflicting criteria in decision making
(both in daily life and in settings such as business, government and medicine). Conflicting criteria are typical
in evaluating options: cost or price is usually one of the main criteria, and some measure of quality is
typically another criterion, easily in conflict with the cost.
In recent years various MCDM techniques have been suggested to do optimization. Among many multi-
criteria techniques AHP, TOPSIS, SAW, PROMETHEE, AHP-FUZZY are the most commonly used
methods.
4. Applicable Areas of MCDM Methods
Manufacturing industry-Selection of Lathe, Best manufacturing process for a given product, best process planning,
Project Selection etc.
Shipping Industry - Crane Selection, Best transportation selection etc.
Electronics Industry- Selection of best refrigerator, Washing Machine, Mobile etc.
Telecommunications Industry–Selection of best network, Selection of best location for mounting tower.
Automobile industry- Four- wheeler and Two- Wheeler Selection, Selection for Two-Stroke Petrol Engines etc.
Economic Sector – Rural development decision making selection, Resource Planning selection etc.
Strategic decision making sector - Risk management decision making selection, Maintenance strategy selection etc.
5. What is AHP-FUZZY?
• Fuzzy set theory is an extension of classical set theory that “allows solving a lot of problems related to dealing
the imprecise and uncertain data”. Fuzzy set theory was first introduced by Zadeh in 1965.
• FAHP is an extension of conventional AHP process and is introduced when the decision maker has to take
decisions in uncertainty circumstances.
• FUZZY-AHP geometric mean method is proposed by Buckley in 1985 and extent analysis method is proposed
by Chang in 1996.
Difference Between Classical Approach and Fuzzy Logic
Classical or Crisp Logic
Considering the speed of a car: 10km/hr→Very Slow 20km/hr→Slow 40km/hr→Medium 60km/hr→High 80km/hr→Very High
Fuzzy Logic
≤ 10km/hr→Very Slow 11-20km/hr→Slow 21-40km/hr→Medium 41-60km/hr→High 61-80km/hr→Very High > 80km/hr →Extreme Speed
In crisp logic either a statement is true (1) or it is not (0), meanwhile fuzzy logic captures the degree to which something is true.
Consider the statement: “Ben agreed to met at 12 o’clock but ben was not puntual”
• Crisp logic: If Ben showed up precisely at 12, he is puntual, otherwise he is too early or too late.
• Fuzzy logic: The degree, to which ben was puntual, can be identified by on how much earlier or later he showed up (e.g. 0, if he showed up 11:45 or
12:15, 1 at 12:00)

15. Conclusions
• The present analysis to find out the acceptable ranking of available laptop computers by using different
hybrid methodology based on market survey that helps the prospective customers to take proper decision in
selecting laptop model and also survey as a guide to the laptop manufacturing companies to frame their
future market strategy.
• From this present analysis it can be concluded that Model 5 is the best laptop model among these 6 available
models in the market based on the opinion of the common laptop users and the ranking of the laptop models
from best to worst is proposed.
• The outcome results and ranking are perfectly same for all the process.
• From this present research work it can also be concluded that the above mentioned diversified MCDM
methodologies is giving the same output results and ranking, moreover the validation is also same for all the
MCDM techniques adopted for this analysis.
Scope for Future Work : Here in this work few important criteria and sub-criteria have considered which
influence the selection of the laptop model. Other criteria and sub-criteria of laptop model can also be
considered in addition to it for this analysis. The scope of work can be extended by applying different MCDM
methods on some more problems and applications of other MCDM tool like MAXMIN, MAXMAX,
ELECTRA, VIKOR, SMART etc. can also be applied to get the possible ranking order and it can be applied
after AHP for getting more probabilistic results considering real-life industrial and domestic problems. The
same decision-making tools can also be applied to other field of applications based on strategic selection e.g.
supplier selection, personnel selection, vendor selection, selection of cranes etc.
