The model presented in the paper simulates the changes of the heating surface temperature under 80 nucleate sites. Process of bubble generation has been modelled by changing of boundary condition on the heating surface. Results of simulation show that when the rate of heat flux absorbed by vapour bubble exceeds a critical rate the phenomenon of spatiotemporal chaos is observed. Calculations of largest Lyapunov exponent show that changes of heating surface temperature have deterministic chaos character. Calculations of correlation dimension show that an atractor created by subsequent values of heating surface temperature has correlation dimension equal to D₂≈3,5.
