Electric Heating Biogas Digester Experimental Research and Numerical Simulation of Fluent

Abstract:

In order to verify the correspondence of numerical simulation and experimental results in the electric heating biogas digester system, an electric heating biogas digester experimentdevice was established, and according to the experimental conditions, software Fluent was used to simulate the process of the heat transfer in the system. Before simulation, analyze theexperimental data through the calculation of heat balance and modify it, then use the modifiedexperimental data, compile UDF to characterize the dynamic boundary conditions, choosestandard turbulence model through the Raleigh number, numerical solving the process. Numericalsimulation results show: simulation process basically reflects the experiment, the simulation dataand experimental data are good agreement, and error within 1%. It is concluded that thenumerical simulation analysis is accurate, method is reliable.
