CFD Black Liquor Pipe Simulations

I have an Inventor-built 3 D model of a pipe run that feeds black liquor past a sensor cavity. I need between four and ten CFD runs, each on a slightly modified version of that assembly, to see which geometry delivers the most even and steady flow through—and then out of—the sensor cavity...
