The feasibility of using the Franz-Keldysh effect in practical
light intensity controlling devices was investigated.
Reverse-biased diodes made from CdS were implemented to obtain
high electric fields necessary for the effect. The three types of
diodes studies were: MIS, metal-semiconductor barrier, and p⁺-n
heterojunction. An expression for the change in...
An experimental investigation was conducted for natural convection
heat transfer in an array of uniformly heated vertical cylinders
in mercury. The test section consisted of seven electrically heated
cylinders of 1.365 inch diameter and 3.825 inch heated length
arranged in an equilateral triangular pattern. In order to preclude
side flow...
This thesis is concerned with the analysis of heat transfer in a tube with forced flow under conditions of an arbitrary variation of wall heat flux both axially and circumferentially. This total study is separated into two distinct problems which are presented separately. The first is the case of a...
In fuel pin fabrication, there is no assurance that a
fuel pellet will be loaded concentrically. Therefore,
azimuthal variations exist in the temperature field giving
rise to asymmetry in the neutron flux distribution and pin
stresses. Calculations must be made to determine the two
dimensional temperature profile which may then...
A study was conducted to determine the heat transfer characteristics
of pin finned heat sinks in natural convection. Three pin
diameters were studied: 0.238 cm, 0.318 cm and 0.396 cm. The pins
were attached to the base in two arrangements, triangular and
rectangular, forming a horizontal array. Pin spacing was...
