    Whether Solidworks can simulate a syringe

      Hi everyone,

       

      I am currently working on a project to analyze a syringe. The outlet is the needle and there is no inlet.The plunger will move and the liquid in the barrel will flow out of the needle into "environment" with certain pressure. What we are intersted in is the force exerted on the plunger and the oulet pressure.

       

      Does Solidworks Flow simulation provide such boundary conditions and allow a plundge move and push the liquid?

       

      Thank you very much

          as soon as you use the word "move", it is likely outside the realm of what flow simulation can do. you need a moving mesh for those types of problems.

           

          the second thing is that you need 2 phase flow (fluid into water)

           

          are you sure this needs to be simulated? is there something unique about this problem that there are no closed form solutions?

              Good morning Jared,

               

              Thank you for your reply.

               

              1) Actually, I just need to simulate the liquid or water flow out of the needle into an "environment"( such as human body)  with certain pressure. How do we deal with such boundary conditions?

               

              2) I am required to simulate the syringe injecting and I don't see a way to simplify the problem. The flow domain will change anyway as the plunger move and push the liquid.
