Engineering research for self-reliance-modeling and simulation perspective
(2009) Oluwole, O. O.
"Engineering research is a sine-qua-non for development of new products, new production processes, hence production lines in the quest for self reliance in any economy. Modeling and simulation is a veritable tool for such research and development. This paper presents the multifaceted use of modeling and simulation as decision tools for engineering facet of an economy drawing examples from two different engineering disciplines- Metallurgical and Civil.

Simulation of riser size from musty zone of unrisered Alsi7mg alloy
(INSInet Publication, 2007) Oluwole, O. O.; Olorunniwo, O. E.; Atanda, P. O.
Solidification simulation packages incorporate risers in their Finite Element meshing programs. The placement of the risers is normally juggled in different positions until the best positions are obtained. Also riser sizes are also determined based on riser size calculations. This work has narrowed down position options by first simulating unrisered castings of an AlSi7Mg alloy. Using the location of the mushy zone and the size of the zone, appropriate size and locations were determined for the riser thus limiting the number of trial and error simulation runs. Using the size and locations of mushy zone it has been discovered that risers of equivalent lineal size should be placed in the locations of these mushy-zones. Simulations were done using a rectangular block and a gas burner.
