Abstract

A set of polynomials is derived to represent surface deformations and experimentally observed Ronchigrams for the Surface Tension Driven Convection Experiment-2 (STDCE-2). The observed deformations are steady state and oscillatory. Steady state deformations are described by radially symmetric polynomials. Oscillatory deformations are described by a modified cylindrical Fourier series. Both satisfy specific experimental boundary conditions.
