ABSTRACT

Vortex refrigeration is a highly sophisticated system that contains a vortex tube which due to centrifugal force expels the internal energy of the air while the air at the centre core is made cooler. In this type of system the effectiveness is too low but considering its small size this can t be ruled off. This is used as personal cooling system in suits that are designed to withstand heat.

Compound Vortex Controlled Combustion
CVCC is a trademark by the Honda Motor Company for a device used to reduce automotive emissions called Compound Vortex Controlled Combustion. This technology allowed Honda's cars to meet the 1970s US Emission requirements without a catalytic converter, and first appeared on the 1975 ED1 engine. It is a form of stratified charge engine.

Honda CVCC engines have normal inlet and exhaust valves, plus a small auxiliary inlet valve which provides a relatively rich air / fuel mixture to a ....etc

The vortex tube was discovered in 1930 by Georges Ranque, a French physics student, was experimenting with a vortex-type pump he had developed when he noticed warm air exhausting from one end, and cold air from the other. Ranque soon forgot about his pump and started a small firm to exploit the commercial potential for this strange device that produced hot and cold air with no moving parts. However, it soon failed and the vortex tube slipped into obscurity until 1945whenRudolphHilsch, a German physicist, published a widely read scientific paper ....etc

DESIGN AND FABRICATION OF PULSE TUBE REFRIGERATION SYSTEM

ABSTRACT
Cooling effect at one end of a hollow tube with a pulsating pressure in the inside gas, was first observed by Gifford and Longsworth in early sixties. This marks the inception of one of the most promising cryogenic refrigerators known as 'pulse tube refrigerator' (PTR). Cryogenics is the science of low temperature. Cryogenics refers to the entire phenomenon occurring below -150 C or 123K. Cryogenic engineering involves the design and development of system ....etc

ABSTRACT
VORTEX GENERATORS
This topic provides basic working principle of a vortex generator suitable for automobiles. Vortex generator has a vital role in increasing the fuel economy and aerodynamic stability. This enables them reduce the drag force acting on it.
There are several methods for positioning the vortex generators over the vehicles. The key results of a simple experiment conducted on Toyota prius exemplifying the advantages of vortex generators discussed here.
