EFFECT OF WIRE WRAPS ON PRESSURE DROP FOR AXIAL TURBULENT FLOW THROUGH ROD BUNDLES
Technical Report
·
OSTI ID:4684072
Pressure drop was determined experimentally for adiabatic axial flow through rod bundle assemblies in a Reynold's number range from approximately 20,000 to 260,000. Bundles of seven and nineteen rods were used in round pipes. Using seven rod bundle assemblies, data were obtained to show pressure drop as a function of the pitch of wires wrapped spirally around each of the six outer rods. Wire wrap pitch was varied from 2 to 18 inches. Experimental data are correlated in terms of friction factors for nonwrapped bundles and drag coefficients for the wire wraps. Pressure drops calculated from these relations generally agree within plus or minus 10% of measured drops. Experimental friction factor values are compared with the Moody smooth tube values. (auth)
