Abstract: This paper presents the second part of experimental results for the mass transfer coefficients in the radial direction from the stagnation point of a multi-jet flow. Two more regions are identified on the target surface, beside the stagnation point/impingement region. One is the region in which the coefficients fall rapidly and the other is the region in which the fall in the coefficients is gradual and smooth as the impinging jet-flow is fully transformed into wall-jet flow. In view of the smooth transition of this fall from the transition region to the wall-jet region, these 2 regions are treated as a single region in the radial direction from the stagnation point. The mass transfer coefficients in this region showed similar trends of stagnation point with variation in nozzle hole and disc distributor, cell size, and height of the disc distributor from the target surface. Correlations of the mass transfer coefficient with a typical flow Reynolds number are also proposed for the region in the radial direction from the stagnation point.
