Measurement of gradient index profiles by Babinet fringe analysis.
A theory for determining one-dimensional ray deflections with the help of distorted Babinet fringes has been developed. An approach for investigating two-dimensional ray deflections has been presented. Applications of the techniques for the study of gradient index glass have been described.
Studies on Deflection Mapping with a Babinet Compensator
Following a recent communication, deflection mapping studies have been made on a heated wire grid, the wake of a reacting drop, and a bat's wing flame. The compensator fringes have been used either as virtual inclined slits or for tracing back the deflected rays. The sensitiveness of the device has been discussed in either case and the corresponding utilities have been pointed out.
Heat and mass transfer in interaction of spherical drops and gas bubbles with a liquid flow
The paper presents a review of works on heat and mass transfer to a single spherical drop published after 1965. The data of the present are correlated. The limiting cases of mass transfer for the resistances present in the continuous and disperse phases only at 0 ⪡ Re ⪡ ⩽ 80 and the general case of comparable phase resistances were studied theoretically. The results of theoretical calculations are compared with the experimental data available.
