Impact of Hydrodynamics on the First Stages of Biofilm Formation in Forward Osmosis with Spacers.

Initial deposition of bacteria is a critical stage during biofilm formation and biofouling development in membrane systems used in the water industry. However, the effects of hydrodynamic conditions on spatiotemporal deposition patterns of bacteria during the initial stages of biofilm formation remain unclear. Large field epifluorescence microscopy enabled and tracking of in a forward osmosis system with spacers during the first 4 h of biofilm formation.

Local data of heat flux, wall temperature and the void phase along the boiling curve during vertical subcooled flow boiling of refrigerant Novec 649 at a copper wall.

This data set contains local experimental data of heat flux, wall temperature and void data profiles for vertical subcooled flow boiling of refrigerant Novec 649 at a copper wall. This data article presents average boiling curves from single-phase convection to fully developed film boiling for six combinations of mass flux and subcooling. Void profiles are provided for void fraction, void detection frequency, void velocity and void ligament size for three characteristic states along each boiling curve.
