CFD Simulation - Liquid/Air Mix - 3 Tank System

I need a programmer to develop a 3D graphic simulation program of a 3-tank system that will allow me to change the amount of air entering the system with a fixed amount of liquid in the system being pumped at a variable rate through the system. The liquid drains from each of the 3 tanks to a common drain line which travels to the pump which pumps the fluid up through an adjustable manifold and back into the top of each of the 3 tanks at a right angle inside the tank to generate a vortex. The air enters at the bottom of tank 1? allowing variable pressure, bubbles up through the liquid allowing me to adjust the hole size of the sparger screen at the bottom of the tank and is then captured at the top of each tank, re-pressurized (allow variable pressure) and sent to the bottom of the next tank in the series.? The end tank is vented at the top however I would like the ability to apply variable? restricted? venting at the top of the last tank. I need an animated simulation so I can make the adjustments and watch what effect it has on both the air and liquid flow. The programmer will need to have their own CFD software and the finished product needs to run on Windows. ## Deliverables The 3 tanks are obviously vertical cylinders. Also need the ability to vary the diameter and height of each tank.
