Abstract

"As the demand for power supply is increasing, the power from nuclear fission is assuming an important role in the field of power production. The enormous quantity of heat generated during the fission process can be utilized for the generation of power. To get maximum advantage out of the fission process, the fission material must be fabricated into a unit of proper shape to permit the control of the process and safe removal of heat generated. This unit, composed of fuel elements is known as the reactor core and is one of the major concerns in nuclear power development.

The shape of the fuel element has considerable effect on the amount of heat transferred from the fuel elements. Since the amount of heat generated in the fuel element is in the order 5 x 105 B/hr. ft2, it is necessary that the fuel elements are designed to give maximum possible heat transfer coefficients.

The achievement of higher heat transfer coefficients is not a problem solely associated with reactor cores. This is the aim of any designer of a heat exchange apparatus.

Higher heat transfer coefficients can be achieved by increasing turbulence over the heat transfer surface. The turbulence can be promoted by an increase in the coolant velocity or by interrupting the flow by shaped objects in the path of flow. Higher heat transfer coefficients can be achieved for interrupted surfaces with low coolant flow rates with a reasonable increase in the pumping power.

The use of twisted plates as interrupters will create a swirling motion in the fluid. The swirling motion is expected to promote higher heat transfer rates.

This investigation is aimed at; 1) the design and construction of an apparatus for the determination of heat transfer coefficients by using an induction heater to generate heat in the test section, 2) the comparison of the results with data available and 3) the evaluation of the effect of a twisted plate on the heat transfer coefficients"--Introduction, pages 7-8.
