The existing literature data permit only qualitatively to trace the behavior of gas bubble, fixed on the solid surface, with the narrow range of Bond numbers (β). For investigation of the profiles, common surface energy of gas bubbles and equilibrium of forces, which retain bubbles on the solid surface in the fluid, the computer model of numerical calculation of the profile, surface square, volume of the gas bubble, fixed on the solid surface, and the forces, acting on a bubble in the fluid for different gas bubbles with the wide range of Bond numbers, corresponding with great precision to real gas bubbles is very important task for application in various fields of science and technology. The paper presents the developed computer model of numerical calculation of gas bubbles with the wide range of Bond numbers, corresponding with great precision to real gas bubbles, fixed on the solid surface in the fluid. The results of model work permitted to use the model for computer modeling of the behavior of real gas bubbles, fixed on the solid surface in the fluid, under gravity change and weightlessness conditions, and under surface tension and contact wetting angle changes both in Earth and weightlessness conditions.
