Studies Of Bistable Fluid Devices For Particle Flow Control, Gerald H. Hogland
Studies Of Bistable Fluid Devices For Particle Flow Control, Gerald H. Hogland
Dissertations and Theses
This study was directed toward the development of a bistable wall attachment Flip-Flop device which was capable of directionally controlling particle flow. The particles were transported by a fluid stream which under the influence of wall attachment. The dominant criteria in the development of the device was the achievement of the highest recovery of particles at the active output, without destroying the wall attachment of the fluid stream The experiment was conducted in several distinct stages; each of which was concerned with at least one aspect of wa1l attachment or particle flow. Results derived from one test were used to …
Comparative Study Of Lightweight And Normal Weight Concrete In Flexure, Mohammad Zareh
Comparative Study Of Lightweight And Normal Weight Concrete In Flexure, Mohammad Zareh
Dissertations and Theses
This investigation represents a comparative study of the flexural behavior of lightweight and normal weight concrete. Both theoretical and experimental moment-curvature characteristics of the tested specimens were used to study the flexural behavior.
A generalized computer program to determine the moment-curvature relationships of a singly reinforced rectangular concrete beam was developed.
For this limited study it was observed that lightweight concrete beams when compared to normal concrete beams achieve comparable moment capacity (about 92% of normal weight concrete) but exhibit higher deflections (about 40% more than normal weight concrete).
