Free Convection Boundary Layer Heat Transfer Analysis Of Isothermal Horizontal Square Plates, Konstantinos E. Tsouras

Theses

The theoretical study presented here examines free convective boundary layer flow and heat transfer over isothermal horizontal square plates.

The boundary layer equations subjected to the appropriate boundary conditions were solved by using Von Karman's approximate integral technique. The analysis was performed by considering an axisymmetric boundary layer because the analyzed phenomenon is three-dimensional in nature. Three-dimensional boundary layer analysis, however, is complicated and the work involved is rather tedious. Consequently, the axisymmetric boundary layer offers a useful alternative. Unfortunately, it was found that this type of analysis is applicable to the case of an upward-facing heated plate only; for …

Application Of Manufacturing Resources Planning To Repetitive Manufacturing Environments, Irma L. Yuen

Theses

Most of the methodology for Manufacturing Systems has been devoted to Job Shops. Frequently the assumption has been made that, because Job Shops are the most complicated their methodology should fit Repetitive Manufacturing as well.
