Pattern longitudinal

The minimum number of the tube rows recommended to establish a proper air flow pattern is 4, although 3 rows can be used. The typical unit has 4-6 rows of tubes, but more can be used. Although more heat can be transferred by increasing the number of tubes, the required fan horsepower will be increased however, this balance must be optimized for an effective economical design. Tubes are laid out on transverse or longitudinal patterns however, the transverse is usually used due to the improved performance related to pressure drop and heat transfer. The tube pitch is quite important for best air-side performance. A typical representative tube arrangement for design optimization is for hare-tube O.D., tinned-tube O.D., and tube pitch ...

Marani et al., 1986). These results were confirmed with several antibodies against SSEA-1. In dissociated rabbit cerebellum the only cell type that was found to express this antigen was the granule cell (Marani and Tetteroo, 1983, Marani et al., 1983, 1986). These results demonstrate the presence of a longitudinal pattern in an intrinsic mitotic...
