Convective heat transfer of laminar droplet flow is analyzed for a low pressure system, where latent heat of evaporation and ratio of liquid density to vapor density is high (for example, water at l atm). The droplet size is considered to be approximately constant but the vapor velocity is considered increasing along the tube. The heat transfer effect of droplets in the vapor stream is treated as distributed heat sink. Results are presented in non‐dimensional form for circular tubes, with constant wall heat flux or constant wall temperature boundary conditions. Distinct heat transfer behavior of droplet flow is revealed.
