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.
Optical technique for the study of convective diffusion from falling drops.
A recently developed deflection mapping technique has been exploited for measurement of rate of mass transfer from a liquid drop falling freely in another liquid medium. Results have been found to be in good agreement with theory. Simultaneously, measurement of the diffusion coefficient is also reported.
Prediction of net pressure on pressure equalized cavities
Abstract A numerical model has been developed for prediction of net pressure on pressure equalized cavities. The results based on this model show good agreement with those obtained from mock-up tests. Parametric studies verify that reductions in cladding load are possible, with proper design of curtain walls.
