Abstract
This work presents experimental results for the onset of boiling of forced flow of nitrogen in channels. Experimental data corresponds to the following conditions: pressure р = (0.9–18.1) × 105 Pa, velocity of circulation w0 = 0.1–1.32 m/s. Circular straight channels with inner diameters of d = 3.87–18.9 mm made of stainless steel (Cr 18%, Ni 10%, Mn 1.5%) were used as test specimens. The influence of pressure and velocity of circulation on temperature difference on wall ΔТob = (Тw–Тsat) corresponding to onset of boiling of liquid was investigated. Simple correlation of calculating for ΔТob was suggested for forced flow of cryogenic liquid in heated channel.
