Research Activities
 

A one-dimensional kinetic computer model of the subsonic Chemical Oxygen-Iodine Laser (COIL) was developed. A set of equations describing the kinetic processes was solved, taking into account the effects of gas temperature and new simplified mixing model of oxygen and iodine molecules.

The temperature rise resulting from deactivation reactions was calculated along the flow for each computation step, using the temperature dependence of the rate constants and of the heat capacitance of laser gas components.

The model of mixing I2 molecules into the oxygen stream is based on the idea that a part of the molecules mixed to the molecular level (and thus accessible to chemical reactions) increases in the flow direction by the exponential law. The remaining (unmixed) I2 molecules are not available for the reactions. The results are compared with the experimental data measured on the COIL device in the Institute of Physics, Prague.
