ShareSpray evaporation heat transfer of R134a on plain tubes.
Author(s) : MOEYKENS S. A., PATE M. B.
Summary
A test facility for performing spray evaporation tests was constructed and results are reported for R134a with horizontal, plain-surface, copper alloy tubes. Pool boiling experiments were also performed and a comparison was made with spray evaporation results under similar conditions. Average heat transfer coefficients were calculated by measuring the average surface temperature with wall-mounted thermocouples and the vapour space temperature with thermocouple probes. For the range of liquid feed rates evaluated, the heat transfer performance for spray evaporation was greater than the pool boiling performance at low heat fluxes and less at the higher heat fluxes.
