Purpose The purpose of this study is to numerically examine the time-dependent energy transport during the natural convection of a heat-generating fluid with temperature-dependent viscosity in a vertical cooling cylinder. Design/methodology/approach The thermo-gravitational convection has been assumed to be laminar and two-dimensional, and governed by a set of dimensionless equations based on the Boussinesq approach with non-primitive functions, including vorticity and stream function. The viscosity of the fluid has been defined as a temperature function with the exponential law. The inner volumetric heat generation is a constant. The cylinder surface is cooled with constant temperature. The analysis has been conducted numerically using the finite difference method of the second order of accuracy on a uniform grid. The in-house computational code has been developed and comprehensively verified using numerical data of other authors and mesh sensitivity analysis. Findings As a result of the computations, the time profiles of the average Nusselt number at the walls of the cavity have been obtained for Rayleigh numbers varying from 103 to 106, whereas the Prandtl number is equal to 7.0
