    Why water does not flow through all my pipe?

    Cl So

      Hi I am new to flow simulation, can anyone please help me with this problem?

      I have tried many many simulations by applying different boundary conditions but still the water does not pass through all my pipes.

      I am really frustrated and I really wanted to know how to find the required pressure / flow rate so that water can pass through all my pipes.


      My only goal is to design a pipe system with nozzles output at least 10 L/min and 100 bar pressure.

      I just hope any simulation can help prove that the pipe system can fulfill this requirement.

      I have attached my SolidWork assembles and parts below. Please Help.

      The simulation results are too big that i could not upload.


      Below are some of my simulation trails, I have tried Internal Flow simulation with different inlet volume flow rate and also external flow sim.

      1st Trial:  Internal Flow simulation

      Inlet Volume Flow Rate = 180 L/min          (since there are 18 output)

      Output Pressure = 100 bar                          (in each nozzle)




      2nd Trial:  Internal Flow simulation

      Inlet Volume Flow Rate = 500 L/min

      Output Pressure = 100 bar



      3rd Trail: External Flow simulation

      Inlet Pressure = 110 bar

      Outlet Volume Flow Rate = 180 L/min (in Total)

      Thank you!
