Experience List



Basin Electric Power Company Flow through a gas pipeline with a check value. Several
Company configurations were modeled with and without guide
vanes.
a Manufacturing company Langranian (dispersed phase, particle tracking) models of
particles undergoing volitiles release and size change.
Several chemical species were also tracked.
Duramax Marine Models of special configuration heat exchangers, to
predict heat transfer coefficients and altP. Comparisons were made with
lab studies and empirically derived design guides. 81
different models were run for the client.
a US chemical plant Model of incinerator including natural convection air flow
inside space between shell and rain shield.
a Texas Chemical plant Chemical reactor design including time dependent kinetic
reactions and gas-liquid mass transfer. Custom CFD programs
and real time reactor models were written.
a non US burner company Sulfur furnace modeling
M&H Industries Gas processing plant: airflow around buildings and
affecting the discharge of 3 “cooling towers” were included.
Flow, temperature with natural convection effects, and
radiation was modeled. Simulation compared very well with
“smoke bomb” field tests of air flow patterns.
