Heat Transfer To Liquid Metals In A Thermal Entrance Region, William B. Harrison

Doctoral Dissertations

The purpose of the present work is to explore analytically and experimentally the heat transfer to liquid metals in turbulent flow within the thermal entrance region of circular tubes having uniform wall temperature. Since liquid metals are characterized by high thermal conductivity, emphasis has been placed on analytical conduction solutions which neglect the contribution to heat transfer that is made by the eddy motion of a fluid in turbulent flow. Three solutions, which differ only in the postulated velocity distribution of the fluid, have been selected for comparison. The postulated velocity distributions are: (l) uniform, (2) parabolic and, (3) velocity …

Experimental Investigation Of Secondary Stresses In Gusset Plates, Wallace Samuel Prescott

Masters Theses

Purpose:

Since it is definitely known that all trussed structures with riveted joints are subjected to secondary stresses, it seemed desirable to investigate the effects of such stress in gusset plates. As previously stated, the term "secondary stresses" as used herein mean those stresses resulting from flexural moments produced in the plane of the truss by the resistance of the joints to free rotation. Therefore, the purpose of this investigation is to study the magnitude and distribution of secondary stresses in gusset plates. Specifically, the purpose is to:

a. Determine the general secondary stress distribution in gusset plates,

b. Determine …
