The client is building one of the largest Thermal Power Generation plant, powered by the supercritical coal-fired power, which is set to be complete by 2020. Currently, at full swing, the plant is producing over 1200 MW energy.

The major hurdles for the client are:

• Greenfield implementation and experience: The need is to build a RCM strategy. Since the project is a greenfield implementation, there is no past data as a reference. The asset strategy has to be developed with prior domain knowledge considering un-interrupted power generation requirement and asset criticality.
• Scalability and Cost: The project implementation is scheduled to be complete within six months, and there was a need for the highest skill levels in . Amongst the various options, the client chose to sign up with �ۿ۴�ý having domain experts available on-demand. While compared to hire resources on contract, train, and then relieve them is otherwise expensive.

Under the terms of the contract, �ۿ۴�ý will identify and analyze each system comprised of multiple equipment. The scope of engagement includes the strategy and implementation of RCM by performing these activities:

• Develop a maintenance strategy for each equipment which includes function, functional failure, failure part, failure mode, failure cause and criticality.
• Formulate a control strategy (maintenance action)to define equipment servicing frequency and on-going condition monitoring along with work instruction, which results in maximizing Overall Equipment Effectiveness (OEE).
• Develop a system level maintenance manual and define limits and maintenance recommendation for all its associated equipment.
• Generate recommendations on spare part requirement, based on the maintenance action. Design a spare part stock holding manual that covers spare parts level characteristics such as OEM / part number details, reorder level, max holding level, similar spare parts quantity, frequency of spares requirement.

“�ۿ۴�ý’s commitment to modernize asset management practices and expertise in asset reliability, condition monitoring, and sustainable maintenance strategy, has helped asset intensive global organizations,” said Kiran Sivadas, EVP, �ۿ۴�ý Engineering. “We are honoured to work with one of the largest producers of Thermal Power and enhance their asset optimization strategy by delivering ROI based maintenance plan.

�ۿ۴�ý brings to its work for the asset-intensive organization experience with sustainable asset management, including an array of services such as condition monitoring, plant maintenance, and spare parts strategy implementation to date.

Heat dissipation is important requirement for all electronic products and should be considered early in the product development phase.  During the design phase, performing thermal analysis using advanced CFD techniques helps to avoid product dysfunctionality by controlling overheating of the product. Most importantly the software also helps to predict temperature and air flow in and around the system, specifying fan details, amount of air to flow across the heat sink and the maximum temperature a component and withstand.

These predictions also enable resource efficient design modifications and virtual model creation on the basis of various tests. Appropriate selection of fan, position and sizes of air vents on the enclosure can also be estimated during the design phase.

There are tremendous short run to long run advantages of using thermal analysis during the design phase. Some of these have been listed below:

• Thermal analysis can provide the results for both natural and forced convection.
• Thermal analysis helps to show the flow curves of the air that pass through the systems and hence it helps to optimize the design.
• The software help in automating the thermal flow within the system with respect to the parameters provided and avoids the physicals prototypes to be made. Hence this in turn reduces the cost.
• It can generate reports such as Air velocity, Air temperature inside and outside the system. It also provides the temperature details of the heat source such as heat sink and the PCB components temperature in the system.
• The thermal analysis will help us to optimize design at a very early concept stage using the same CAD data file and can continue to reshape the design at the proto stage. Hence doing this analysis at an early stage prevents redesign at a later stage and also warranty repairs related to thermal.

Applications: The CFD software can be used in several area’s for example in HVAC (Heat, Ventilation and Cooling), Consumer products, Medical equipment’s, Electronics systems, and Power systems and so on.

CFD Tools:  Ansys ICE PACK with Fluent solver, Autodesk Simulation CFD and Mentor Graphics FloTherm.

Advances in design software, such as high-speed PCB design tools, have made these things possible. But as components become ever more tightly packed and miniaturized, and key process parameters ever more numerous, negative forces come into play – such as increased power consumption, enhanced parameter variability, and heat generation – the last being a particular threat.

The increased number of key process parameters in modern CMOS (Complementary metal-oxide semiconductor) VLSI designs causes dramatic on-chip substrate and metal line temperature rises, which impact on reliability, causing timing failure and performance degradation through electromigration and other effects.

It is estimated that up to 50% of all integrated circuit failures are heat-related. Accurate thermal analysis is therefore essential to system hardware design. It is essential to analyze and reduce on-chip temperature variations and identify and eradicate hotspots before a VLSI design enters commercial production.

A lot of research has gone into CPU power consumption and heat dissipation, with the development of high-performance, low power VLSI and FPGA designs. A number of high-speed incorporate thermal analysis software, often with 3D modelling simulations. However, the data can be difficult to interpret, if thermal physics is not your first language.

The capabilities of printed circuit boards – memory capacity, processing speed, etc, are linked to this, and similarly are increasing exponentially. Moore’s Law is the scientific explanation of what many refer to as the technology explosion; it defines the history of technological change.

When you pack thousands of transistors onto a single chip, the array is described as a Very Large Scale Integrated, or . One example is the microprocessor – except that today we speak in terms of billions, rather than thousands of transistors. And this has come at some cost. VLSI designs are in danger of becoming the victim of their own success.

Microprocessor circuits are now more complex, more tightly packed than ever before. But with this comes higher power consumption, and with it the problem of heat dissipation. Threshold voltages and CPU power dissipation (PD) – the way in which microprocessors consume and dissipate energy, some of which is lost as heat – have not kept pace with advancing technology. Scaling designs down is no good unless logic complexity is maintained. This has been achieved – but only by increasing CPU PD.

Nonetheless, VLSI designs are being improved, mainly through the use of thermal analysis and CFD software. We at �ۿ۴�ý Technologies offer state-of-the-art VLSI design solutions to help maintain your edge in the competitive, fast-moving world of digital technology.
