Droplet Departure Characteristics and - Heat transfer

Dropwise condensation has received significant attention due to its great potential to enhance heat transfer by the rapid droplet removal. In this work, droplet departure characteristics on a vertical surface, especially the droplet departure retention at low steam pressure and its effect on the heat transfer performance are investigated experimentally.

Heat Transfer Surface Fouling in Boilers

Fouling in boilers is dependent on the type of boiler design and the fuel being fired. The main factor that leads to fouling in a coal fired boiler is the increase in percentage of the low melting constituents. Fouling in boiler heat transfer area is different from slagging. Even though both effects heat transfer, fouling happens in the convection heat transfer surface in the boiler and

SUPERCRITICAL HEAT TRANSFER - thermopedia.com

The effect of pressure on nucleate boiling is well established: as the pressure is raised towards the critical pressure the heat transfer coefficient increases, and the limiting heat flux for transition from nucleate to film boiling first increases, reaches a maximum at a value of p/pc of about 0.35, and then decreases.
