Advantages Of A "Special Nozzles" Cooling Tunnel

Enrico Freri, OMAV SpA


ABSTRACT --- This paper describes the application of special nozzles in a spray
cooling system. These nozzles are engineered to optimize the atomization process
and, therefore, the cooling process. The main advantages of this application are:

  • Reduced consumption of water and air, because the water flow rate may be
    varied according to needs, and the atomization air is at low pressure
  • Optimum regulation of the cooling capacity over a wide range; This happens
    because it is possible to vary the fluid supply from 0 to 100 percent for each
    nozzle by adjusting only the water supply and keeping the air supply constant
  • Excellent flexibility in cooling due to the wide possibility of regulation and the
    nozzles’ positioning which allow the maximum effectiveness on difficult sections

From the software point of view the interface between man and operator has been
simplified, so that setting up the parameters and set points is easier for the
operators.The paper will specify the tunnel characteristics and the results on the
profile, supplying data obtained from tests proves made on practical applications.
