MEASUREMENTS OF FRICTION, HEAT-TRANSFER, AND MASS-TRANSFER IN A SEVERELY OUTGASSING TUBE BANK

The influence of outgassing on the transport coefficients for flow thr ough a staggered row tube bank was measured. Friction factors and heat and mass transfer coefficients were measured for 8000 < Re < 16 000 a nd blowing rates up to nu(0)/U-infinity = 5 x 10(-3). Because of outga ssing, heat and mass transfer coefficients reduced by as much as 70%. New blowing factors and correction functions were obtained that quanti fy the effect of outgassing on the transport coefficients. (C) 1998 El sevier Science Ltd. All rights reserved.
