    On my new job i am required to look into new ways of thinking. Because of this i was wondering if it were possible if i used capillaries of a solid (if you know any substance fitting, please tell me) to measure the flow of a liquid, by viewing it by infrared.

    1) I wish to know what kind of materials pop up to mind that don't bend or break, don't melt easily, and that heat up quite well when water is run through it with some pressure.

    2) I also want to know if flow can be measured between these capillaries using the infrared camera.


    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..

    Since you are looking at different ways of thinking, perhaps you could change this system around a little?

    If you have a fine tube with a fluid flowing through it, and a gas or liquid at a different temperature flowing past it, say at right angles then there will be heat transfer from one to the other. At zero flow, the tube will be at the same temperature as the surrounding fluid. As the flow rate is increased, the temperature differential will increase. A suitably sensitive IR thermometer should be able to detect this.
    ( I think)

    The point of this, is to arrange a random number of capillaries, at a random angle of one another, and then see where most flow and pressure is going to be. The problem in fluid dynamics is measuring the flow in a capillary, and this could solve it if i can make some kind of calibration.

    Ah. I think perhaps that you have not set out the statement of your problem very clearly.
    In fact, I still can't understand it.
    Anyway, it seems that thermal methods along the lines of my suggestion are in existance already.

    I wasn't proposing something totally new and unreal. I just wanted to implement this method of reading pressure on every spot of an ultraflat, grooved layer of polymer, glass, or whartever works best in showing localised forming of heat.

    This all to be able to read pressure/flow, and derive flow from this by using computer models.

    This may seem silly at first, but how about a thermochromic material as in a "mood ring" that changes color with temperature? I also see similar materials in forehead thermometer strips. So, you'd have this material as one surface and glass as the other surface so you can view/record the color and their changes.

    I need to set up a Pay Pal account so you can pay me for my brilliant ideas.

    I have the same problem that Warron had. I can't figure out what you're trying to accomplish. Why is the fluid flowing through a capillary tube? Do you really expect it to heat up perceptibly as it flows through? Perhaps it would help to explain your overall purpose with this project.

    I am trying to create a model of flow/pressure on a small scale. It's a model of the soil where groundwater flows. I want to be able to predict the speed, the impact of viscosity, and the effect from the size of the capillaries.

    And no, i don't expect it to heat up. The problem is, there is no other way yet. I am looking for possibilities, would it be able to heat up, then how can i make it more local, more predictable, etc.
