Model and Numerical Simulation of Combusted Products and Unreleased Caloric of OTTO-II Fuel Adding FEFO

摘要

In this paper, the mathematical model and numerical simulation of the OTTO- II fuel adding double-formaldehyde (FEFO) in different proportion under different temperature and pressure is studied, and the software MATLAB is used to solve the model. The results of the calculation show that the quantities of the unburned components of the combusted products of the OTTO- II fuel can be reduced to some extent by adding FEFO, and the unreleased caloric of the unburned components can be decreased too. With the growing of the proportion of FEFO in the mixed fuel, the unburned components and unreleased caloric become less. However, the regulation that the unburned components and unreleased caloric vary with temperature and pressure is the same.
