摘要：

Pressure drop and forced convection heat transfer were studied in the boiling nitrogen flow in a horizontal square pipe with a side of 12 mm at inlet pressure between 0.1 and 0.15 MPa with a mass flux between 70 and 2000 kg/m(2)-s and with a heat flux of 5, 10 and 20 kW/m(2). Accordingly, the flow and heat transfer mechanisms specific to square pipe were elucidated, and the applicability to cryogenic fluids of pressure drop and heat transfer models originally proposed for room temperature fluids was clarified.
