Subcooled flow boiling of water has been investigated for a heating surface of 50mm in length and 20mm in width placed on the bottom of horizontal rectangular channel under lower pressure of TOkPa.abs and higher pressure of 150kPa.abs in the boiling fluid loop. The mass flow rate of liquid is fixed at 500kg/m^2s (0.5m/s). The critical heat fluxes are well coincident with the existence theories modified with pressure. Microbubble emission boiling (MEB) occurs easily at lower liquid subcooling, 20K for an example, and the heat flux obtained is higher than CHF. The pressure gives strongly effect on MEB generation in subcooled flow boiling.
