Stirling Engine

A Stirling engine, which is a heat engine of external combustion piston engine type whose heat exchange process allows for the near ideal efficiency in the conversion of the heat into the mechanical movement by the following Carnot cycle as closely as is practically possible with the given materials.

Stirling engine’s invention is credited to Scottish clergyman Rev. Robert Stirling in 1816 who made significant improvements to the earlier designs and took out the first patent on it. Robert Stirling was later assisted in its development by his engineer brother named James Stirling.

The inventors sought to create a safer alternative to steam engines of the time, whose boilers will often exploded due to the high pressure of steam and the inadequate materials. It will convert any temperature difference directly into the movement.

The Stirling engine will works by repeated heating and cooling of usually sealed amount of working gas, usually air or other gases such as hydrogen or helium. This is accomplished by moving the gas between hot & cold heat exchangers, the hot heat exchanger being a chamber in thermal contact with an external heat source, for e.g. a fuel burner, and the cold heat exchanger being a chamber in the thermal contact with an external heat sink, for e.g. air fins.

The gas will follow the behavior described by gas laws which describe how a gas pressure, temperature and the volume are related. When the gas will be heated, because it is in sealed chamber, the pressure rises and this

Self Compacting Concrete

This Civil Engineering Topics is discussing with the Self Compacting Concrete. Concrete is one of the most used construction material in the world and if correctly composed, it can be vary durable and thus save considerable society resources in the maintenance cost. Self compacting concrete is one of the subjects of concrete technology. The various investigations have been carried out and hence the concrete has been used in practical structures. Here we are providing a brief introduction to self compacting concrete which is also known as SCC is given. The definition and motivation for the development of Self compacting concrete have been discussed. The Self compacting concrete has some advantages over the normal concrete and also some disadvantages over the normal concrete. An approach has been made to study the various aspects of the Self compacting concrete, such as types of Self compacting concrete, materials used and testing methods, in detail. This Civil Engineering paper also touches the economical considerations, applications and future development of the Self compacting concrete. A concrete that places itself - 'SCC’ A well-proportioned Self compacting concrete can flow under it’s own weight through and around congested reinforcement filling forms completely and producing a void free mass with no vibration and without segregation problems. When large quantity of heavy reinforcement is to be placed in RC member it is difficult to ensure that the form works get completely filled with concrete that is fully compacted without

Smart Materials

While talking about the Smart Materials, its a very interesting Engineering Seminar Topic in the field of Civil Engineering. A new generation of materials called smart materials is changing the way a structural system is going to be designed, built & monitored. Advances in the composite materials, instrumentation and the sensing technology in the combination with the new generation of the actuator systems based on the Piezoelectric ceramics and shape Memory Alloys have made this into possible.

The Shape memory alloys have found applications in a variety of the high performance products. It is ranging from the aircraft hydraulic coupling and electrical connectors to surgical suture anchors. Since the material can be generate high actuation forces in the response to temperature changes, shape memory alloys have the potential to serve as an alternative to the solenoids, which is special significance in the area of the smart

Advanced Construction Materials

A research on the advanced construction materials has given a push by many factors. In late eighty's, the aerospace industry has seen a steady decline; alternative use of new materials develop for aerospace industry is made possible to construction sector. Exotic materials such as advance polymers & high performance carbon fibre sheeting are researched upon to develop their potential use in the construction of the corrosion free buildings.
The advanced materials are looking on as next generation materials for high techbuildings. Materials that has been researched not only enhances the durability of buildings, but they also have ability to reduce the manpower usage, reduce or eliminating corrosion, and enhancing strength of the structural members. One of new materials which is being rapidly developed & applied is the use of continuous fibres in the construction. Continuous fibres are widely used in the retrofitting and strengthening type of works. Fibres could be impregnat in the resin at factory to produce stiff fibre reinforce polymer plate or they could be soaked in a resin just prior to application at site. Fibre Reinforce Polymer (FRP) utilises the high performance fibres such as the carbon aramid, kevlar and the other glass fibres encapsulated in the resin matrix. This technology has been developed to an alternative to the conventional steel reinforcement for using in the concrete structure primarily
