This method, though comparatively simple, is attended by several disadvantages there is a 

It is better to employ some method by which the change of receiver may be effected without, admitting air at all, and there are two forms of apparatus in general use by means of which this may be done. 

Bredt s Apparatus.—To the end of the delivery tube from the still-head is attached a round-bottomed flask with a long neck to which are sealed three narrow tubes a, b, and c, approximately at right angles to it (Fig. 11), and a fourth 0 2

Quiben and Thome (2007a,b) presented an experimental and analytical investigation of two-phase pressure drops during evaporation in horizontal tubes. Experiments were performed under diabatic conditions in tubes of d = S and 13 mm in the range of vapor quality x = 0—1, mass velocity G = 70—700kg/m s, heat flux q = 6.0—57.5 kW/m. The test fluids were R-134a, R-22 and R-410A. The results... 

A theoretical model for the prediction of the critical heat flux of refrigerants flowing in heated, round micro-channels has been developed by Revellin and Thome (2008). The model is based on the two-phase conservation equations and includes the effect of the height of the interfacial waves of the annular film. Validation has been carried out by comparing the model with experimental results presented by Wojtan et al. (2006), Qu and Mudawar (2004), Bowers and Mudawar (1994), Lazareck and Black (1982). More than 96% of the data for water and R-113, R-134a, R-245fa were predicted within 20%.
