Abstract

The aim of the work was to determine the rate and uniformity of temperature distribution in the amount of biogas plant constructed by UrFU, \“Avanguard” PLC and \“Gildia-M” Ltd on the stage of warming and achieving the rated work conditions corresponding to the mesophilic fermentation process. A computer model of the biogas reactor, considering the main unit features, was created. The installation heating was carried out by uniform thermal energy supply through the outer surface of the vessel full of substrate. Numerical solution was achieved by the finite volume method which has the following features. The calculation results in the form of temperature fields and the substrate particle trajectories for several time moments are given in this paper. The results analysis shows the possibility to use the model for the thermohydraulic computation of various operation modes of the bioreactor. Keywords: mesophilic fermentation process, biogas, simulation, transient mode.
