The invention discloses a method for calculating the condensation rate of steam containing non-condensable gas on the inner wall surface of a containment under unknown steam flow. The method comprises the following steps: 1, inputting adjustable parameters: condensing wall surface numbers, steam latent heat and steam inlet mass flow fine adjustment parameters; 2, searching a first layer of grids of the condensation wall surface; 3, reading various parameters of the grid; and 4, judging whether the grid is condensed or not and calculating a quality source item of the grid. And 5, calculating a grid momentum source item and an energy source item. 6, judging whether all grids of the wall surface corresponding to the condensation wall surface number are cyclically finished or not, and if so, carrying out calculation in the next step; and if not, retrieving the next grid, and returning to the step 3. And 7, calculating the condensation rate of the current time step length. And 8, adjusting the mass flow of a steam
