Simulating turbulators in fire tubes | SOLIDWORKS Forums

I have recently begun using Flow Simulation to analyze fire-tube boiler designs. For those not familiar, a fire-tube boiler is basically a shell-and-tube heat exchanger that uses hot combustion gasses in the tubes to heat water in the shell. The tubes are simple straight pipes, but they also have Brock turbulators (wavy strips of metal) in them.

How Boilers Keep the Plants and Refineries Running Smoothly

Fire Tube Boilers - Fire tube boilers utilize a system of tubes through which the heat source, or "fire", passes. The tubes are surrounded by water and the water is heated as the tubes also rise in temperature. Eventually steam is released for use.
