Holdup function according to Duns & Ros Equation in 2.62 pg 43 Ovadia Shoham Equation 2.39, 2.310, 2.311, 2.312 in Brown pg 113
dunsros.holdup(vsl, liq.sg, if.tens, vsg, diam, liq.visc, pres)
| vsl | liquid superficial velocity ft/s |
|---|---|
| liq.sg | liquid specif gravity |
| if.tens | interfacial tension TODO: pass liq.dens instead of liq.sg TODO: move pres to start of params list |
| vsg | superficial velocity of gas ft/s |
| diam | diameter of tubing ft |
| liq.visc | liquid viscosity cp |
| pres | pressure psia |
