RESEARCH, DEVELOPMENT & INNOVATION
Russula R & D collaborates with Industrial Mathematics
team on three important projects
Project 1 - Percentage of martensite for steel 1020 in a section
with small size corrugation. The blue areas represent a 0% level
of martensite and the red areas show where martensite has
formed.
Project 1 - Real metallographic analysis conducted on the
steel
Project 2 - A velocity map section in its x component for a cross
section of the combustion chamber. This simulation aims to identify
preferred channels with increased exhaust convection heat-
Project 1 - 3D modeling of rebar. Different cross sections
were taken to create the grid, previous to the FEM analysis.
Project 2 - Particle stream lines from a burner in the equalization
zone of a reheating furnace. The model shows the effect of each
burner in the heating of the whole combustion chamber.
Mathematics Workshop, proposing the topic Numerical
simulation of transient flows in a billet reheating furnace chamber.
Numerical modeling of billet reheating in a reheating furnace
clearly depends on an adequate description of convective
flows. Previous numerical simulations (stationary
character) have revealed the presence of complex
structures in the flow of gases from the furnace, which
help to understand the phenomena of heat transfer in
the furnace. Direct modeling of the escape gases by a
predictive tool can be integrated into the plant control
to substantially improve the results in the heat transfer
calculations due to convective effect.
Gas fluxes are strongly non-stationary (even when the
furnace charging is) because of the furnace´s design.
Thus we need to understand how the furnace behavior
affects the dynamic structures of gas flow. Including
this behavior within the logic of mathematical
model logic of the heating furnace (commercially
known as "Level 2C") may improve the calculation of
the bar temperature.
