Organic fuels, including lycopodium, have a high potential for energy release, however, in order to
increase the energy released in the combustion process of these fuels, it is suggested to use
additives such as metals. Therefore, in this research, the triple fuel of Lycopodium, iron and
aluminum has been studied. In this thesis, firstly, the modeling of the limit combustion of triple
fuel, lycopodium fuel, aluminum fuel and iron fuel is investigated. In this section, thermodynamic
balance and fuel mass fraction changes have been investigated. Then, the semi- limit combustion
modeling of triple fuel, lycopodium fuel, aluminum fuel and iron fuel is investigated. In this
modeling, the effect of heat recirculation on temperature, speed and flame front is studied. In the
next step, the effect of flame radiation is added to the semi-limit combustion modeling and its
effects on temperature, speed and flame front are investigated in the presence and absence of
radiation. Also, in order to investigate the movement of fuel particles and the parameters
affecting the thermophoretic force, the movement path of the particles is investigated using the
Lagrangian point of view. Finally, the fluctuating combustion of triple fuel is investigated in order
to investigate the effect of diameter, equivalence ratio and initial temperature on flame
temperature fluctuations. According to the results, by reducing the diameter from 30 to 10
micrometers, the flame speed increases from 0.051 to 0.153 m/s. Also, by increasing the diameter
from 500 to 700 nm, the flame front is moved to a place with a distance of 1.46 times farther. As
the ambient temperature increases from 300 to 700, the maximum range of temperature
fluctuations decreases by 1.33 times.
