Shell and Helical coils are eminent coiled tubes which have been used in diversity of solicitations e.g. heat recovery,
air-conditioning and preservation schemes, chemical reactors and dairy practices. Shell and Helical coil heat exchanger is the
recent improvement of heat exchangers, to accomplish the industrial demand. A shell and helical coil are necessary for various
heat exchangers, nuclear reactors and in chemical engineering, for of large quantity of heat is conveying in a slight space with
high heat transmission rates and slight habitation time distributions even it suffers through a disadvantage of larger pressure
drop.
