The effects of nozzle height and orifice size on spray evaporation heat transfer performance for a low-finned, triangular-pitch tube bundle with R134a.

Author(s) : MOEYKENS S. A., PATE M. B.

Summary

Shell-side heat transfer coefficients were measured through various heat flux. Both circular and rectangular spray patterns were evaluated at different nozzle heights over the tube bundle. It was found that several nozzle configurations yielded shell-side heat transfer coefficients higher than those found in the pool-boiling test. Bundle heat transfer performance showed dependence on the nozzle orifice size and wall heat flux, with only a weak dependence on the type of spray pattern and the nozzle height over the top row. It was determined with collector tests that orifice size directly affected the amount of refrigerant contacting the tube bundle.
