Equations for Bilateral Heat Transfer to Fluids Flowing in Concentric Annuli (open access)

Equations for Bilateral Heat Transfer to Fluids Flowing in Concentric Annuli

Abstract: "Theoretical equations have been derived for calculating heat transfer coefficients for fluids flowing through concentric annuli for the following two cases: (A) constant and equal heat fluxes from both walls, and (B) constant, but unequal, heat fluxes from the walls, with equal wall temperatures at a given axial position along annular channel. In the derivations, the conditions of fully-established flow, and independence of physical properties with temperature variation across the flow channel, were assumed. The only geometrical parameter in this general case is the radius ratio r2/r1, and in the study it was varied from 1.0 to 10.0."

Magnetic Properties of Some Intra-Rare Earth Alloys (open access)

Magnetic Properties of Some Intra-Rare Earth Alloys

Technical report. From Abstract : "Paramagnetic susceptibilities of samarium structure alloys in the systems La-Gd, Nd-Y, Nd-Tm, and Ce-Y were measured from 4.2 - 300°K to determine what effect the formation of this structure has on the magnetic properties of the alloys. Susceptibility maxima were observed in the Nd-Y and Nd-Tm alloys, at 34.5 and 28.5°K, respectively. Slope changes were observed in the curve of 1/x versus T for the La-Gd alloy at 155 and 130°K, and the susceptibility of this alloy remained temperature-independent from 130-7°K. A rather poorly defined region of constant susceptibility was also observed or the Ce-Y alloy, from 26-37°K. Above these transition temperatures, the alloys obeyed the Curie-Weiss law, the susceptibilities of the La-Gd and Ce-Y samples indicating the possibility of electron transfer occurring in these cases."

Cation Exchange in Acetone-Water-Hydrochloric Acid (open access)

Cation Exchange in Acetone-Water-Hydrochloric Acid

Abstract: Distribution coefficients have been measured for the partition of metal ions between cation exchange resin and acetone-water-hydrochloric acid solutions. the differences in distribution coefficients of metal ions are greater in acetone-water media than in aqueous media of the same hydrochloric acid concentration. Using distribution coefficient data, conditions for column separations of mixtures can be selected. Column separations of metal ion mixtures can be effected by eluting with acetone-water-hydrochloric acid solutions of different compositions. Successful separations of a number of mixtures are reported.
