This work is dedicated to exact numerical modeling of modal dispersion and thermal noise in arbitrary cylindrical symmetric WGM structure. We develop a method and compare the results with experimental data from literature. We show that the real form of the resonator makes small influence on the thermorefractive noise spectrum and old infinite-space formula is quite universal. The modelled Brownian noise is in a good agreement with the experiment.
