Abstract

Two FORTRAN 77 finite element analysis source codes, by 1.N. Reddy, were input into a PC, debugged, executed, and tested successfully. These programs are available to students interested in implementing a good finite element analysis source code on a PC or on a workstation in one or two dimensions. The programs can solve problems relating to heat transfer, stresses, beam analysis, frames, trusses, plane elasticity, plate bending, and laminar viscous incompressible fluids with various node and element combinations.

The two-dimensional program was used to obtain the velocity distributions in a 90 degree duct bend with incoming and exiting fully developed flows so that particle deposition analysis could be studied varying the inertia parameter, S. It was found that at values of S below 1.0, the maximum particle deposition occurred at the point where the 90 degree duct bend met the exit vertical section; for S=1.0, deposition was even throughout the duct; finally, for S greater than 1.0, maximum particle deposition occurred at the center of the 90 degree turn of the duct. All particles were deposited on the upper wall of the duct. Extra anti-corrosive agents should be placed in the area of maximum particle deposition when the particulate matter is harmful to the duct material.
