Water Flow Models
I am looking to optimize the flow in my tank by the strategic placement of the returns and the pumps. I was wondering if there’s a downloadable program available what could/would model the tank and show the movement of water. Some sort of water flow model is available for groundwater movement but I’m having trouble finding one for water tanks?

The problem with doing that for a tank is that every tank will be different. Different rock arrangements, different corals and coral growth etc. will make that very variable. Best thing to do is the feed something like cyclopeze, brine shrimp nauplii, or similar and watch how the food blows around

I asked my professor the very same thing because I had hoped during our fluid mechanics class he would touch on this subject.
His answer was that to model something like dynamic fluid motion in a 3D program would take a lot of computing power and some very LARGE and complex equations. I am sure such a program exists for windtunnel applications, because air and water can be regarded in the same way most of the time, but such a program isn't readily available like Google Sketch. Try NASA AMES or MIT

Smooth and mostly generic geometric shapes are not that hard. Now flow in a tank is another story just think of all the different textures on the surface of the rock and corals all those greatly affect how water is going to flow and modeling anything close to a piece of live rock would take tons of time!

Several 3d modeling programs could do that(Maya, 3d max). Of course you's have to learn to use the programs first

Fluid flow in an empty tank will be nothing like the flow in an aquascaped tank... you really have nothing to gain for the trouble.

Because its fun?
I used Sketchup to model a 3D violin for the hell of it why not it will look pritty and keep me out of trouble! |

2 programs i know of would do what you are looking for.
1 is FLUENT though learning to program is quite an undertaking. Plus you have to have a mesh made up in a second program first. 2 is Solid Works They have a few fluid analysis tools though they take a beast of a computer or a good chunk of time. SW is a lot more user friendly and if you have an experience with 3d drawing programs you won't have much trouble. Only real drawback is the price. Licensed versions of both are expensive. But in this hobby what isn't. PM me if you have any questions, Id be glad to help. |
