  1. Title of the talk: Engine Down-sizing
  2. Resource Person: Mr. Nandu S
  3. Date, Time & Venue : 01/03/2017, 3:20 PM to 3:40 PM – CLC 402

With a growing number of manufacturers choosing to install more compact and efficient engines into their machines, the benefits of engine downsizing are becoming more apparent. By integrating a smaller displacement engine, operators can benefit from a reduction in fuel burn and lower greenhouse gas emissions, while higher power density helps to improve the overall efficiency of smaller engines.Many manufacturers are reducing engine capacity and number of cylinders. By adding a boosting device (turbocharger or supercharger) and direct injection technology, they provide a powerful engine with similar performance to a much larger engine, but with much improved efficiency and reduced carbon emissions. A smaller engine is also often lighter, so the car can be lighter and therefore nimbler. Reducing the number of cylinders also reduces the amount of friction in the engine, increasing the efficiency.

The knowledge enhancement program discussed the relevance of engine downsizing and turbocharging in automobiles.


  1. Title of the talk: Technological advancements in LNG Operations
  2. Resource Person: Mr. Easwaran Nampoothiry K
  3. Date, Time & Venue : 26/10/2016, 9:10 AM to 9:40 PM – CLC 402

Natural gas is a mixture of gases containing primarily hydro­carbon gases. It is colorless and odorless in its pure form. It is the cleanest fossil fuel with the lowest carbon dioxide emissions. Natural gas is an important fuel source as well as a major feedstock for fertilizers and petrochemicals. Natural gas can be used either as compressed natural gas (CNG) or liquefied natural gas (LNG). The use of Natural Gas Vehicles (NGVs) also facilitates energy security and energy diversity.Liquefaction of natural gas andits chemical processing are energy-intensive facilities, such that any enhancement of their efficiency will result in abundant reduction of energy consumption and greenhouse gas emissions. Nitrogen expansion cycles are widely used for liquefaction process. The FOM and yield of the system can be improved significantly by precooling the feed gas using R-410, propane, CO2 refrigeration systems. The LNG is transported over large distances in ships having Cargo Containment Systems (CCS). The inner vessel/ primary barrier of CCS made up of stainless steel. Sometimes it may fail by impact loads due to LNG cavitation during operation, the stiffness and strengthof the primary barrier is increased much to endure the impact pressure of LNG, which increased thetransfer of impact load to foam insulation panels under the primary barrier. The increase of impact loadto the foam insulation panels will induce crack propagation into the insulation foam panels due to thelow toughness of insulation foams at cryogenic temperatures. An impact isolation system was developed using glass fiber composite mats to lower the impact load transmission into the foam insulation panels.


  1. Title of the talk: Micromachining - MicroEDM
  2. Resource Person: Mr. George John
  3. Date, Time & Venue : 21/10/2016, 1:30 PM to 2:00 PM – CLC 403

  1. Title of the talk: PSMA coating for property enhancement of PMCs
  2. Resource Person: Mr. Sreekumar C
  3. Date, Time & Venue : 26/08/2016, 9:20 AM to 9:50 AM – CLC 403

One of the most important factor for obtaining good reinforcement by fibre in a polymer matrix composite is the adequate adhesion between matrix and composite. Adhesion between the fibre and matrix depends on the structure and polarity of these materials which in turn can be improved by the various surface modifications and chemical treatment. The treatment causes the fibres to fibrillate into the ultimate and the roughening of the surface facilitate the mechanical bonding with the matrix material.

PS-M coating is one of the novel method of surface treatment which imparts a promising enhancement in the additive characteristics of the material. Here, treatment is carried out on the SCF fibre in the SCF-Glass fibre composite, in which Fibres of average length 10 mm were immersed in 5% NaOH solution for different time intervals at room temperature and at boiling temperature. Finally the fibres were repeatedly washed with water containing little acetic acid and then dried in an air oven at about 70°C for 24 hrs. The specimens were then analysed for various mechanical properties, including tensile, impact and flexural strength.  The coating of PS-MA on the fibre surface marginally enhanced the properties. This may be due to the compatible nature of the aromatic groups present in the coated fibre and the matrix.

Manufacturers focus on developing manufacturing systems that produce superior quality products with acceptable features of safety, quality and with on-time delivery at minimum cost. Turning is one of the common machining processes and is widely used in a variety of manufacturing industries and the performance is indicated by surface quality. The determination of optimum cutting parameters for achieving better surface finish is a matter of research for the past few years.

The presentation focused on the development of ANN models for prediction of surface finish with independent variables feed, cutting speed and depth of cut. Turning was conducted on AISI 4140 steel of diameter 38mm and 280 mm length. Surface roughness was measured with speed varying from 145 rpm to 598 rpm, feed varying  from 0.05mm/rev to 0.4mm/rev and depth of cut as 0.06mm to 0.26 mm.


  1. Title of the talk: Ergonomics
  2. Resource Person: Mr. Arun K Varghese
  3. Date, Time & Venue : 30/09/2016, 1:30 PM to 2:00 PM – CLC 403

Ergonomics in industries and office space mainly about the fatigue reduction of humans. Human factors and ergonomics (commonly referred to as HF&E), also known as comfort design, functional design, and systems, is the practice of designing products, systems, or processes to take proper account of the interaction between them and the people who use them. The field has seen contributions from numerous disciplines, such as psychology, engineering, biomechanics, industrial design, physiology, and anthropometry. In essence, it is the study of designing equipment, devices and processes that fit the human body and its cognitive abilities. The two terms "human factors" and "ergonomics" are essentially synonymous. Human factors and ergonomics are concerned with the "fit" between the user, equipment and their environments. It takes account of the user's capabilities and limitations in seeking to ensure that tasks, functions, information and the environment suit each user. The three main fields of research in ergonomics including Physical, cognitive and organisational ergonomics were dealt in detail.

  2. Resource Person: Mr. Jerin George
  3. Date, Time & Venue : 29/4/2016, 11:45 AM to 12:15 PM – CLC 403

Activities in any production industry can be categorised into Value-Adding and Non-Value Adding activities, based on whether the activity adds direct value to a product. Value Stream Analysis is a technique used in Lean Manufacturing Systems, where the focus is on eliminating or reducing the non-value adding activities.

Value Stream Mapping is a tool for visual representation of all activities in the production line, which is used to categorise the activities to analyse the Current State, and then improve the processes to design the Future State of the process. This presentation illustrated a case study done in an industry in which significant process improvements were done through Value Stream Analysis.
