We present a theoretical model to numerically evaluate the dynamics of a coupled Bose field at finite temperature. This model is used to study a proposed table-top experiment using a two-species Bose-Einstein condensate (BEC) to simulate the inflationary universe. By applying the Bogoliubov method and the truncated Wigner method to include both the thermal fluctuations and the quantum fluctuations, we present a feasibility study and possible observations of the experiment at finite temperature condition.
