    Heat transfer in a pipe flow

    Prabhu Prakash

      Dear all,

      kindly help me with the following problem.

      Pipe ID = 300 mm

      Pipe OD = 320 mm

      Pipe Length = 15 m

       

      Fluid = steam

      Pipe material AISI 1330 (density = 7870 Kg/m^3 | Sp. heat = 472 J/Kg K | Th. conductivity = 51.9 W/m K)

       

      Available Boundary Conditions at Inlet are:

      Mass flow = 90 tons/hr

      Velocity = 17m/s

      Pressure = 64 Bar

      Temperature = 480 Celsius

       

      Assumed film co-efficient = 14.5 W/m^2 K

       

      I have solved the problem, but the outputs are not as expected. Also the flow trajectories are not reaching the exit point.

      What kind of settings to be followed throughout.

      Can you kindly help me in solving the problem.
