For this purpose the cell containing the red solution of dye in ethanol is placed in the interferometer setup. Then, the convection heat flow is induced in the sample by 532nm Gaussian laser beam. The profile of the flow velocity is investigated based on the Fourier analysis of the interferogram and hydrodynamic model for the convection current. M3 ER -
