# Study of Georgian Natural Waters Thermodynamic Parameters Behavior by Means of Original Fluids Bubble Boiling Method

## Main Article Content

## Abstract

Some years ago the authors suggested new fluids bubble boiling method (BBM) for modeling vertical convection processes having place in the geospheres. Then they were developed in our recent articles for artificial solutions and analyzed by means of T (t), ΔS (T), and T (ρ) experimental curves for definition of admixture of the mass content density of any solution or natural waters. In suggested article, luckily, were obtained optimal values of the liquid volume, the heating intensity, and temperature measurement frequency at any solution concentration allowed us, without waste of time and any trouble, to work out the original method BBM for modeling of above mentioned geophysical convective motions in the laboratory conditions and provide at that stage the planned experiments. Thus, it was investigated: the regimes of heating, the first smallest air-vapour micro-bubbles (d ≈ 10^{-2} cm), then macro-bubbles (d ≈ 2 ∙ 10^{-1} cm) boiling before the end of experiments (T = T_{max }= T_{ } ≥ 100 ^{0}C). The experimental curves showed clearly the succession of the regimes: (1) thermal (T_{0} = 10 ^{0}С < T < T_{1} = 40 ^{0}С); (2) microscale bubbles (T ≤ T_{1} = 40 ^{0}C); (3) macroscale bubbles (T ≤ T_{2} = 80 ^{0}C); (4) intensive, in the form of some winding vertical bubble-chains (80 ^{0}C < T ≤ T_{3} = 100 ^{0}C); (5) bubble-projectile (T ≥ T_{3} = 100 ^{0}C ). To the end of experiments, mean value of loss of liquid mass was equal to about 10 % of the whole mass. At last, it was constructed universal experimental curves, connecting the values of parameters of the liquids at the points of the boiling regimes, changed and obtained three linear curves T (t), ΔS (T), and T (ρ), and sinusoidal ΔT (Δt) one for natural waters of Georgia and artificial chemical matter solutions of any density at the points of the regime break.
