Single Phase – Laminar Flow Systems

hiTRAN Matrix Elements provide consistent performance along the tube length, unlike plain bore tubes where heat transfer deteriorates as tube length increases (laminar boundary layer effect).

Design uncertainty of plain tube heat transfer rates in the transition region is also removed, as tube-side heat transfer performance with hiTRAN Elements remains proportional to the flow rate over the whole Reynolds range.

As the tube-side heat transfer rate is increased by the Elements, the temperature of the wall and tube-side fluid film will approach that of the bulk tube-side fluid. Lowering temperature differences between the wall and fluid film will reduce the rate of fouling when temperature-sensitive fluids are being heated or cooled.

With increased film mixing particle deposition rates will also be reduced, keeping tubes cleaner and the heat exchanger in service longer.
