It is established that the critical heat flux density in boiling nanofluids depends on the size and material of nanoparticles and on the heater diameter. The critical heat flux density grows with increasing size of nanoparticles and drops with increasing diameter of the heater....
In the experimental conditions, the concept of "first critical heatflux density" becomes meaningless, and may evidently be replaced by the concept of "limiting heat-flux density." In the latter case, the heat-transfer coefficients reach a maximum value for the given coating and decrease either ...

摘要: Katto (1970) developed a series of dimensionless correlations for the critical heat flux, qcr", in uniformly heated round tubes. For low void, or DNB-type, critical heat flux conditions, Katto was able to correlate the available data...
The Zuber model is modified by combining three factors to propose a critical heat flux model suitable for mixed wetting surfaces. With the increase of heat flux, the bubble detachment frequency decreases, the bubble detachment diameter increases and the nucleation site density basically shows ...
Normal operation of the thermosyphon cannot be obtained at any liquid of water, R113, and R22 for a small tube diameter of less than 2 mm within a wide range of L/D-4.8 to 960 and density ratio of ρι/ρG=6.17 to 1602. 展开 关键词: Phase change Critical heat flux Open-...
